I'm trying to think of the practical issues of the synthesis of dimethylamine as it is a gas obviously soluble in water. Using hydrochloric would work
i would assume not sure the concentration 12M or less. Formic acid is also a product and how would i deal with purifying?
thanks in advancekristofvagyok - 3-11-2012 at 17:49
Basic organic chemistry rule 1: a strong acid will make a salt more readily with a base than a weak acid.
So if you add HCl to the HNMe2, then HNMe2.HCl will be formed and the excess HCl and the formic acid could be distilled out.
Method no2 is to add some NaOH to the methylamine and formic acid solution and here the formic acid will react to give sodium formate and the
dimethylamine could be distilled out.
I would recommend the method no1 and convert back the base.HCl with some solid NaOH/KOH and distill the dimethylamine to a dry ice cooled flask (it
has a horrible smell, so be careful).
Shouldn't this fit in the beginnings section?chemisch - 3-11-2012 at 19:30
that makes a ton of sense. thank you. chemisch - 3-11-2012 at 20:29
Oh, one more quick question how would one attempt to concentrate? because attempting to make a 40% aqs solution sounds difficultNicodem - 4-11-2012 at 03:36
