how to convert beta hydroxy butyrate to gamma hydroxy butyrate???

GHB got a bum rap.  it's just more nonsense hysteria to justify the bloated budgets of the police state.\n\nThat aside, you don't convert beta to gamma.  suggesting an elimination failed to consider that the double bond formed will be more stable in conjugation with the carbonyl group; you'll get crotonic acid.  Subsequent hydrolysis would give you a mixture of alpha and beta.\n\nyou'd have much better luck trying to figure out a way to do it starting with GABA.\n\nOf course, if you have to ask, you lack the skilz.

CH3CH2CH2CH3 + CL2 -hV--> \nCH3CH2(CL)CHCH3 + HCL ..\n\nwhat are the ways to get the CL at the end of the chain..so that\n\nCH3CH2CH2CH2CL + 2NA + CLCH2CH2CH2CH3\n--->CH3--------CH3\n\nThat's a radical reaction, the chlorination of an alkane with chlorine in UV light. The intermediate is a carbon radical and secondary radicals are more stable than primary. There are also more secondary carbons on this molecule. So probability and reaction kinetics dictates that the primary alkyl halide will be a minor product.\n\nI guess, if this were my synthesis, I'd:\n\n1. Put the glucose in HCl to cleave the anomers it likes to make.\n\n2. Esterify the carboxlic acid with whatever's available (Fisher esterification with MeOH, for example)\n\n3. Reduce the ester with Diisobutyl aluminium hydride (DIBALH)\n\n4. React the aldehyde with 1 equivalent of Ethyl Magnesium Bromide (Grignard)\n\n5. Reduce the hydroxy groups with a Barton-McCombie deoxygenation, although I've never seen it done in a case like this.\n\nThen again:\n\nI'd go to the stockroom and save my research advisor a lot of money. :)

Oleic acid ((Z)-9-octadecenoic acid) + Br2 ---> 9,10-dibromooctadecanoic acid \n\nOr: \n\nC18H34O2 + Br2 ----> C18H34O2Br2

2-hexanol. Look at the link, I think this is what you want.

There is only one I can think of. 1-hexyne can be deprotonated with sodium in liquid ammonia, to yield a very basic, nucleophilic anion.\n\n2-hexyne has no such proton to remove.\n\n===\nThe poster below is also correct. NMR would be the fastest way. You wouldn't even have to use a deuterated solvent. (because the hexyne would be a liquid).

if I understand the question:\nto go from cal/gK to cal/gC you'd convert the temp from K to C. that's simply subtract 273. degrees C = degrees K - 273.\nif you're trying to go from j/kg to j/mol you need to know the identity of the substance you're talking about. specifically you must know the molecular weight of the substance. first convert kg to grams(multiply by 1000) then divide by the M Wt of the compound.

No need to break it down to "molecular" other wise, try this: Sodium thiosulphate. Dont just use it coz they all vary in their Ph U know the basisity or acidity they concentrate.

Hey cable_ray,\n     One of the most easiest way to get the recipie you require or any other synthesis can be found on the following website. It is the organic synthesis website, maintained by cambridgesoft.com. It is a free service they provide. You can use it. Just put in the name of the ether you want to produce eg. dimethyl ether, diethyl ether, etc. I am an MSc by research student. So you can also mail me. I will surely reply. my mail add is jchemie@gmail.com

There is a formula...but this is much easier\n\nhttp://www.onlineconversion.com/temperature.htm

This might not be the simplest way possible, but here goes:\n\n(Starting with propanone)\n1. H3O+/I2 (to form 1-iodopropanone)\n2. (Ph)3P (triphenylphosphine forms the ylide)\n3. butanone* (Wittig reaction, now you should have hepta-3-ene-2,6-one)\n4. H2/Pd/C (hydrogenate the C=C; hopefully this'll leave the C=O's alone)\n5. H3O+ (intramolecular aldol condensation to close the ring, with dehydration to form the C=C double bond)\n\n*can be made from propylaldehyde and CH3MgBr\n\nNote: No guarantees this'll work as desired. :)

Go to "protein" on wikipedia ( put, protein, in address bar ) then scroll down to "synthesis", for the process. It is too  long a story for my typing skills. The wiki article is not too technical.

Online conversion figures these things out for you!\n\nYou have to choose liquid or dry matter.  But the answer is there.

mix concetrated sulphuric acid to the sodium acetate, the reaction will produce acetic acid and sodium sulphate.\n\nif you take all the water out of the sodium acetate, you will end up with 100% pure acetic acid.\n\nH2SO4 + CH2COONa => CH3COOH + Na2SO4\n(unbalanced equation)
