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.
