-Fluorinate toluene with F2 (highly controlled) or FCl or F5Cl, or DAST or one of these other nice fluorinators - gives the trifluoride on the methyl carbon\n-Nitrate it with nitric acid/sulfuric acid - CF3 is withdrawing so nitro goes on the 3-position\n-Reduce the nitro with Sn/HCl or H2/Pd\n-Nitrate again - the amino protonates and directs to the 5-position\n-Titrate the water to basic pH and extract with solvent like ether.  Concentrate and purify - probably crystallizes nicely.

You don't need a chemical reaction.\nFrozen carbon dioxide, known as dry ice, can do the job.\nIt's in a thermos container, but as soon as it touches the air, it sublimates into gaz, producing the smoke. (To make more, put it in water instead.)  And it's heavier than air, so it stays close to the ground.  And it's not expensive!

Ultrasonic cleaners might be the best solution.\n\nHere is an excerpt from the source listed below: \n\nAlthough a range of possible alternative products is available today, experience has shown that substitution of TRI is not easy and even not feasible for a number of specific cases, either for technical or economical reasons. For all cases, substitution of TRI needs a thorough evaluation of all process aspects. For this reason we intend to work with the authorities in order to prevent a blanket implementation of forced substitution, and allow sustainable and continued safe use of TRI. \n\nThe alternatives you will probably consider first are the chlorinated solvents perchloroethylene (PER) and methylene chloride (MC). They match closest the technical features of TRI, such as non-flammability, high solvency power, a wide range of material compatibility and excellent drying and recycling properties.\n\nBeside PER and MC, you have probably also heard about other alternatives such as aqueous (water-based) alkaline systems, flammable solvents (e.g. hydrocarbons or modified alcohol based formulations), supercritical CO2 or hydrofluorocarbons (HFCs), etc.\n\nIt is impossible to say definitively which technology is best. That depends on your specific application, on what you are cleaning, which materials you want to remove, the cleanliness required, the variability of the parts cleaned, the throughput to be achieved, the cycle times, etc. \n\nFor example, for the cleaning of parts between two water-based manufacturing steps (e.g. galvanising), aqueous systems may be better, since parts are put into water phase again later and no energy-intensive drying step to remove the water is required. \n\nIf you need to have very clean and dry surfaces (for coating or surface hardening, for example) and if you have a variety of different metals or blind holes, narrow distances and very fine orifices or a lot of residual oil to clean, hydrocarbons or aqueous systems may not clean and dry well enough. In these cases, chlorinated solvents will offer most often the best solution as they are compatible with most materials, have a high cleaning power, are easy to dry, don't leave residual films and are easy to recycle with high quality by distillation. In addition, chlorinated solvents are today best suited to be used in modern closed systems with minimal losses. Their ecological performance has very much increased and, when used in well-operated metal cleaning systems, they outperform aqueous cleaning as long as drying is required. This has been shown by a Life Cycle Analysis carried out by Ecobilan. \n\nPER comes closest to TRI in technical performance and is often the first choice candidate as an alternative to TRI. However, it shows clear inherent technical differences, which need to be taken into consideration. On one side, PER offers a lower volatility and therefore is advantageous to minimise emissions in closed equipment. On the other side, PER has a lower solvency power and is therefore normally used at a higher cleaning temperature to achieve similar performance. This may raise concerns regarding the compatibility with specific metal working fluids and temperature-sensitive parts. \n\nMethylene chloride (MC) shows excellent cleaning properties already at low temperatures, favouring the cleaning of temperature sensitive parts. However, its high volatility makes emission control more difficult and requires special equipment.\n\nHydrofluorocarbons (HFC) and hydrofluorocarbon ethers (HFCE) are very expensive and show very limited solvency power. A thorough evaluation of the global warming potential is also required to choose the adequate product.

Simple, just follow this process respectively. Since its one whole of a solution. Begin with distillation. This will get rid of the oil, sand+dirt and the salty water. \n\nDirt+sand - you could add water and then sieve the dirt and water. as for the dirt distilation.\n\nSalty water - you just need to heat the solution and distill the vapour to have your water other wise the salt will form crystals and loose water to the atmosphere thus nice dry sodium cloride crystals. \n\nHope you got answered....

You could use hot KMn04, but what about using a chromium oxidizing agent, such as Cr03 or NaCr04 ... you might get a cleaner oxidation.

Take two plastic cups.  Perforate both cup bottoms and insert graphite rods.  Invert two glass jars over the cup bottoms so that the ends of the graphite rods are nearly sealed.  Then connect the ends of graphite on the open end of the cups with wires to a 6V battery (check that the batteries are fresh!).    Disconnect wire-battery connection till later.\n\nhen, prepare an electrolyte solution in a PLASTIC tub. Here, there are two options.  One is a solution of NaCl and the other is dilute H2SO4.  I tried NaCl before, but it gives a generally low yield.  Never tried H2SO4.  From what I heard, I recommend you use that- but use DILUTE H2SO4 (careful not to touch any).   Always make sure (either) solution is warm, so that electrolyte will be surely distributed.  \n\nFinally, lower the cups+jars in such a way that the water goes up 2/3 of the way up the jars (the graphite rods should be completely submerged).    Then, reconnect wire-battery and wait... until water levels drop dramatically (takes a long time).  Your anode (negative terminal) jar contains 02. while your cathode (positive terminal) jar contains H2.  Check presence of O2 by putting a smoldering splint into  the (still) inverted jar- it will reignite.  Check presence of H2 by bringing lit splint into the (still) inverted jar- it will go 'pop'.\n\nHope this works for you.

welld oint this can be tricky without proper sterile procedure... however it is not impossible...\n\n\nget a sleeve of plastic or glass petri dishes\n\nmix up a mixture of Malt Extract And Agar... and put it in a sealable vessle that can be pressure cooked or boiled at a high temperature...\n\nIn a clean environment after boiling or pressure cooking for about 15-25 minutes, \n\ntake the vessle and pour your agar plates...\n\ntake the dishes and let them cool in a very clean environment\n\nonce cool....\n\ntake a qtip and swab the inside of your mouth really well\n\nopen each plate and swab the surface with the qtip\n\nrepeat for each plate\n\nincubate the plates at room temperature for about 3 days or so\n\nyou should see some growth\n\nor you can do it this way\n\nhttp://www.science-projects.com/NAplates.htm\n\nwww . Science-Projects . com \n\n\n\n\n--------------------------------------------------------------------------------\n\nMaking Nutrient Agar ("NA") Plates\n \n| Site's Table of Contents | Site's Index |\n\n\n--------------------------------------------------------------------------------\n\nThere are several ways to make NA plates, all depending on what you have to start with. The well equipped person has clean and sterile empty petri plates, and a bottle of NA powder sitting on the shelf. That person needs only to follow the directions on the bottle. As it is the purpose of this website to assist those who, being mostly young students, have neither NA powder nor even petri plates. What are they to do? Here's what! \n\nPETRI PLATES FROM SCRATCH\n(click this to find ready-made plates) \n\nFirst, you must find something that simulates a petri plate. Rather shallow glass custard cups covered by a double thickness of aluminum foil works well. \n\nSecond, you must have the nutrient agar to put in them. What might you use as a alternative to the commercially available microbiological stuff? The answer is canned beef or chicken broth (supermarket) and agar (health foods store; sometimes called "agar agar"). \n\nThird, you must sterilize these things in appropriate combinations. Included in the following steps will be the way to use a pressure cooker. There is NO substitute for a pressure cooker or autoclave, which is an automated pressure cooker. Boiling is not a sterilizing condition. Boiling doesn't work! The only commonly employed sterilizing conditions are wet heat at 120°c (250°F) for 20 minutes (pressure cooker), or dry heat in excess of 190°c (375°F) or more for an hour or more (oven). \n\n\nMeasure and record the amount of water that half-fills a custard cup. \nDetermine the number of plates (custard cups) you will need to use, and from that the amount of medium you need to make to half-fill all the cups. \nEmpty a can of fatfree beef or chicken broth into a large measuring cup and dilute, if necessary, with water as per the instructions on the side of the can. Mix. Discard the excess beyond what you need for your cups. Pour this into a sauce pan. \nAdd 1 level teaspoon of agar per 2/3 cup of broth. Stir the required amount of agar into the COLD broth in the sauce pan. \nTurn on the heat, and with constant and continuous stirring and/or swirling bring just to a boil. Keep swirling, and then adding small amounts of heat, and do this until all the granules of agar are dissolved. Agar solutions burn very easily - just like making gravy (in which you have added another polysaccharide as a thickening agent). An alternative way to do it is to place the broth/agar mix into a glass bowl and place it in a microwave oven. But do this cautiously as the mix will suddenly foam up. So be ready to shut off the energy at any moment. Give the dissolving solution a swirl, and microwave a bit longer. Swirl and energize repeatedly until all the granules are dissolved.§ \nDistribute the hot medium among the cups you need. \nPlate pieces of double-thick aluminum foil over the cups so that at leas

I assume this question involves using common sugar (sucrose) are the fuel.\n\nThe answer would depend on how you are extracting the energy out of the sugar as well as just how large of a mass (rocket + ...) you want to move to the moon.\nYour question is far too vague (and meaningless) without A LOT more details.

How to make a simple Van de Graaff Generator\n\nITEMS:\nPlastic Tupperware (microwave oven safe)\nSome wires\nNail\nSmall DC motor \nPiece of PVC pipe (approx. 3.8 cm in diameter)\nBroad rubber band \nWooden skewer\nPlastic bag\nRoll of tape\nSoft drink can\nMineral water bottle\n2 3volt batteries\nBattery holder (optional)\n\nPutting it together:\n1) Cut a hole in the middle of the bottom of the plastic container.\n2) Glue/tape the motor to the lid, making sure the shaft is at the centre of the lid.\n3) Using a hot nail (can be heated at the stove), make two holes near each other for the wires of the motor\n4) Thread the wires through the two holes (the two wires will connect to the batteries)\n5) Cover the container with the lid. (Inverted container in this case)\n6)Make another hole, perpendicular the motor shaft\n7) Thread another wire through(this will be your ground wire) \n8) Make the appropriate measurements for cutting your PVC pipe length and grooves(where the stick will rest)\n9) To make the roller, just stick tape to your stick and go round and round and round.\n10) Place the PCV tube on the lid, perpendicular to the motor. \n11) Thread the stick thru the rubber band and place it in the grooves.\n12) Make sure both rollers are parallel to each other when you thread the bottom of the band to the other "roller"\n13) Cut the top of the soft drink can.\n14) Cut both ends of the mineral water bottle off, making sure that it isn’t shorter than the PVC pipe.\n15) Make a hole near the top of the bottle.\n16) Strip some wire, twist it, and poke it through the hole.\n17) Electrically connect the copper wire to the soft drink can.\n18) Tape everything in place.\n\nWhen you put everything together, you get a crude Van de Graaff generator. Make sure the combs (end of wires) are near the belt and rollers. Make sure that when you run it, the belt doesn't slip off. If it does, make sure both rollers are parallel to each other. Also, try to superglue the motor to the Tupperware lid.\n\nWhen you first run it try taping strips of tissue paper to the can. It should start to rise seconds after the batteries are connected. If this fails, put your finger near one of the tissue strips. The strip should be attracted to your finger.\n\nPlaces with high humidity can be a real problem for electrostatic experiments. Try working in an air conditioned room to help overcome the problem.\n\nThe last two links are the best ones and both include detailed step by step process with pictures.
