PART TWO: Can I turn water into methanol or ethanol, and how?

First, commercial production of methanol is accomplished by the catalytic reduction of CO according to the following equation:\n\nCO + 2H2 ---> CH3OH\n\nSo yes, it's very possible to add carbon to your hydrogen to make methanol. In fact, it's constantly being done on the industrial scale. Most catalysts are based on a mixture of Cu, ZnO and alumina, although the precise details of the best catalysts are something of a trade secret.\n\nThere are still a couple of things to keep in mind with your proposal. The first is that H2 is *very* expensive to make by electrolyzing water. If you use an applied potential of 2.5V it will take around around 7.4 kWh of electricity to electrolyze 1 liter of H2O (assuming I did my math right). That's a *lot* of expensive electricity to replace only a liter or so of conventional fuel. Unfortunately, until technology improves there is really isn't any practical way to generate that much electricity by solar or wind power.\n\nWhile I am a big proponent of alternative fuels, it's often not as simple as it seems to replace traditional fossil fuels. It's generally easy to convert energy from one form to another (for example electricity to hydrogen to methanol), but it doesn't solve the basic problem of getting the energy to begin with. Still, it's a problem we need to work on since almost all of our energy comes from non-renewable resources.

By itself, water is an unreactive substance by nature. So you cannot separate oxygen and hydrogen from the water molecules. However, there is only one ay in hich this canbe done: electrolysis.\n\nIt involves the passage of an electric current into a liquid, which naturally conducts electricity. Electrodes are used to pass the electric current. At both the electrodes, gases are evolved, depending upon the liquid.\n\nSome acid or alkali should be added to water for the evolution of gases, namely hydogen and oxygen at the electrodes.\n\n\n\nIt can be mass-produced, but the process is too costly. An application could be to use hydrogen in hydrogen powered cars to replace the more polluting petrol powered cars. \n\nMoreover, oxygen is also obtained by the fractional distillation of liquid air. It involves cooling air by decreasing the its pressure by placing them in special containers, capable of bearing atmospheric pressure. This process is more economical, compared to electrolysis. Liquid oxygen and hydrogen is used to power rockets in order to propel them into space. This process for the production of liquid oxygen and hydrogen is mass produced nowadays to power rocket and hydrogen powered cars. \n\nThanks

There are several possibilities.\n\nThe TEOS solubility in water is negligible.  It is not much better in methanol, but it does adhere to the ethyl group of ethanol to some degree.\n\nThe boil point of ethanol is 78.4 degrees C, which is higher than the boiling point of methanol (at 64.7 degrees).  This might be a factor.\n\nThe last has to do with the physical size and role of the alcohol as a catalyst.  Methanol is smaller and may not have the correct geometry.\n\nI totally agree with the suggestion to experiment, using the same molar quantities for methanol and ethanol.  You might also want to try n-propyl alcohol to give additional data.\n\nBy the way, chemistry being what it is, you might try searching for additional answers using an alternate name for the TEOS.  It is also called Tetraethoxysilane.

It would make water (H2O).

sugar in water forms a true solution, and the size of the particles is less than a nanometer\nit is nearly impossible for us to seperate sugar frm water using home made techniques\nhowever there r lab techniques thro which the sugar particles can be crystallised.evaporation will not help in getting the sugar back\n\nwhat is the purpose of doing all these to a super saturated solution????\nu can just evaporate the water frm a super saturated soln(no clips and nothin else)\nhowever in case u have little amt of sugar in water, what will u do?????

sugars + yeast + water = ethanol ;I wouldn't drink it though unless you know what you are doing. There is always the possibility of methanol contamination that's the reason for distillation. IF YOU DRINK IT YOU COULD GO BLIND!!!

KMnO4 is an oxidizing agent.\n\nit will turn ethanol into ethanal (or acetylaldehyde).  if there is a great excess of potassium permanganate, it will turn ethanal into ethanoic acid (or acetic acid).\n\nbasically, both steps involve decreasing the number of bonds from carbon to hydrogen and increasing the number of bonds from carbon to oxygen.

an easy example you can remember is H2O(water).\nif u want a more difficult one, u can use CH3COOH(acetic acid)!\n\nALL DE BEST!

This is an interesting question.  Since water is a byproduct of all combustion using anything with oxygen and hydrogen such as fossil fuels or wood or just about anything you can think of that burns it itself does not burn.  If you add alcohol to it the alcohol it self will burn but not the water it will evaporate.  It is not possible to burn water unless you get it back to its original components.  You can do this with electrolosys.  So what you could do is design a car that runs on oxygen and hydrogen.  Take some water home stick 2 electrodes in it and it would turn into oxygen and hydrogen, then you would take those tanks to your car and power it that way.  It would be a very efficient method since the ammount of energy you use to make the gas is the same ammount of energy that you would get from burning the gas.  And Electricity is cheap.  Fossil fuel isn't.  Also you lose potential energy when you burn fossil fuels since they are not atomized.  Gas is.  You could add carbide to the water.....That would give you acetelene gas, and you could fuel your car that way but carbide is expensive as well.

How about a friggin car you can run on food waste?  I'm tired of paying rich bastards who play price fixing games making money off me.  Ethanol or Methanol sound like a better alternative if we can all start making our own fuel without blowing up a few city blocks.\n\nSaw a news bit about a water-fueled motor the other day...\n\nJust read that answer above.  170 miles on a cell?!?  Are you freakin' kidding me?!?  My 113hp/69ft. lb motorcycle with a 4.5 gal tank does over 200 miles!  AND, it does wheelies!

If you remove a molecule of water (H2O) from C2H5OH (ethanol) you are going to end up with C2H4  (Ethene).

You'd need 4 L of dehydrated alcohol and 1 L of water in order to get a 80% solution. Getting a dry solution of ethanol would be a challenge, though, so I would expect it to be closer to 75-77% in actuality (but theoretically 80)

Water does autodisassociate, but methanol does not. Methanol's proton is only removed with a very strong base, like sodium hydride or lithium diisopropyl amine. The species created is an alkoxide and they are quite reactive.\n\nSome substances can dissolve in methanol if they are polar (e.g. have a dipole moment caused by the inequality of electron charge distribution)

You could rig a "Dean-Stark Trap" on the side of your condensor. That will eliminate water from your esterification (assuming its similar to the Fisher esterification) and force the production of more water and product, until one of the reagents is used up or an equilibrium is achieved.\n\nAnother method would be TLC, comparing the starting reaction mixture to the final product.\n\nSpectroscopy (NMR, IR) could be used.\n\nFinally, you could just put some of your sample into a GC-MS.
