Title: PPA
Post by: malvaxman on September 24, 2002, 11:51:00 AM: There is a question that I would very much that someone could answer: Has anyone here in their dreams really succeded to get PPA from BA and L-alanine?

...or is this possibility only something that some guy who is dead since 75 years have succeded with in a 100 year old book.
Title: Alanine
Post by: Chemikaze on September 24, 2002, 12:37:00 PM: I suggest you to find a better method (BA + nitromethane).
Alanine is VERY expensive,and it wouldn`t be very thrifty,to say the least, to do it this way,would it?

IIRC psychokitty posted a method of synth-ing alcohols from BA and nitro...IIRC

Title: NitroEthane, not nitromethane
Post by: PrimoPyro on September 24, 2002, 01:20:00 PM: Nitromethane produces a chain that is one carbon short of the desired length. You need nitroethane, which is illegal to own or purchase, and therefore must also be manufactured, at least if you are a USA bee.

And all the referenced patents in that patent description.
That is a very convenient process, I see no reason why alanine can't be used in place of glycine.
Title: So you say alanine is expensive...
Post by: malvaxman on September 25, 2002, 01:02:00 PM: How much could it cost? I guess about 50$/100g. The value of shit coming out in the end of the proces is alot more worth I can tell you.
Title: aldrich
Post by: Aurelius on September 28, 2002, 03:12:00 AM: hope this isn't posting a source ;) ..

boy, isn't that expensive- might have to sell the body to get that kind of money ;)

Post by: uncle_buck on September 29, 2002, 09:50:00 AM: Bees,

Alanine is available for US$20/kilo and can be shipped anywhere in the world as a sports -related commercial supplement.

Nitroethane is also available to the common man from one or two sources (in the states, at least). Seek and you'll find...
