       preferential neutralization of methylamine     

Hi,

Well i found this little titbit on orgsyn.org
http://www.orgsyn.org/orgsyn/orgsyn/prepContent.asp?prep=CV1P0347

An entirely different method for preparing pure methylamine hydrochloride free of ammonium chloride has been described.1 It is based on the fact that when a mixture of methylamine and ammonia reacts with an insufficient quantity of hydrochloric acid the methylamine is preferentially neutralized and the ammonia left free.
1. Sharp and Solomon, J. Chem. Soc. 1477 (1931).



Does any one know anything about this method, SWI4 can't seem to find the ref.....

Thanks
