ethylamine

[Eng., ., ethyl, and amine (q. v.).] Chem.: NH2 C2H5, amido-ethane, a liquid boiling at 18°. It mixes with water in all proportions. Obtained by distilling ethyl isocyanate, OC=N-C2H5, with caustic potash; by the action of nascent hydrogen on ace to nitril, CH3 CN; and by heating ethyl iodide and alcohol saturated with dry ammonia gas to 100° in sealed tubes and distilling the liquid with caustic potash, when a mixture of ethylamine, diand tri-ethylamine is obtained; the mixture is treated with oxalic ether and distilled, when triethylamine, N (C2H5)3, comes over. It is an oil, boiling at 89°; the residue consists of die thy lox amide (soluble in water), and converted into oxalate of pota ium and ethylamine, NH2 C2H5, by boiling with caustic potash. The part insoluble in water is the ethylic ether of diethyl-oxamic acid; this distilled with caustic potash yields diethyl amine, an inflammable liquid, boiling at 58°. amine is a powerful base, decomposing metallic salts. It is decomposed by nitrous acid, forming nitrous ether, and free nitrogen is liberated, NH2C2H5+2HNO2=C2H5 NO2+2H2O+N2. Ethylamine with cyanic acid forms ethyl carbamide or ethyl urea. The salts of ethylamine are generally easily soluble in alcohol. The hydro chlorate, C2H5NH2 HCI, crystallizes in deliquescent prisms, which melt at 80°. It forms a double salt, with platinic chloride.
