nah. ethylamine is exactly as it sounds.. two-carbon ethyl group attached to an amino group. H3C-CH2-NH2. mask..hate to say it, but you're gonna have to make the stuff. acetaldehyde + ammonium chloride + NaOH
polymer is on the right track, also ethylene with ammonia H2C=CH2 + NH3 → CH3CH2NH2 also try your local library on organic chemistry texts, text books, and other books and try googling it a bit. Remember a little google goes a long way (made that up myself haha)
4-Dimethylaminobenzene was a chemical in the mixture used to create. Booster Blue. Fact or fiction.. lol....long long way to go home...
