One of the equivalents of hydrogen and carburetted hydrogen C 4 H 6, the generator of the series, having been replaced by 1 equi- valent of amide (NH a ). In order to obtain ethylammonia, cyanic or cyanuric ether is boiled in a distilling apparatus with an excess of potassa, the va- pours being collected in a well-cooled receiver containing a small quantity of water, which takes the ethylammonia in solution, and thus becomes strongly alkaline, with an intense ammoniacal odour, although it does ...contain a trace of free ammonia. This liquid is saturated with chlorohydric acid and evaporated, when crystals are METHYLAMMONIA. 623 obtained which dissolve completely in absolute alcohol, and are again deposited, by evaporation, in crystalline lamellae. This compound is chlorohydrate of ethylammonia C 4 H 7 N, HC1, and is distinguished from chlorohydrate of ammonia by its solubility in absolute alcohol. The chlorohydrate of ethylammonia, perfectly dried, is mixed with double its weight of quicklime, and introduced into a long tube closed at one end, so as to fill one-half of it ; and the other half being filled with fragments of caustic potassa, a disengagement- tube, which enters a flask surrounded by a refrigerating mixture, is adapted to it.
