METHYLAMINE HYDROCHLORIDUM.
METHYLAMINE HYDROCHLORIDE.
CH6NCl = 67-508.
Methylamine hydrochloride, CH3NH2,HCl, is prepared by neutralising an aqueous solution of methylamine with hydrochloric acid, and evaporating to
dryness. The residue dissolves readily in boiling alcohol, which, on cooling, deposits the salt in crystals. These crystals at the
moment of their formation appear iridescent by reflected light.
It occurs in fine, large laminae, colourless, and deliquescent. Very soluble in water and in alcohol ; insoluble in chloroform. Its solubility
in alcohol distinguishes it from ammonium chloride. Melting-point, 222°. Heated in an open vessel to a high temperature, it volatilises in
dense vapours, which condense to a white powder on cold surfaces. It forms with many metallic chlorides well- crystallised double salts.
