amines

pl. [Eng. am=ammonia, or am Chem. Acids consisting of a bivalent or trivalent acid radical combined with hydroxyl (OH)' and amidogen (NH2), as succinamic monium; suffix -ine.] acid (C4H4O2)"ΟΗ. ΝΗ2. Chem. Compound ammonias, having the hydrogen replaced, atom for atom, by alcohol radicals. When one atom of H is replaced, almutium. [ALMUCE.] 2. Any vest or flowing garment. (Nares.) "Came forth with pilgrim steps, in amice gray." Milton: P. R.. iv. 427. they are called mon amines; when two H atoms are replaced, diamines; when three atoms of H, tri amines. They are obtained by heating the iodides of the alcohol radicals with ammonia. Thus iodide of ethyl and ammonia yields ethylamine, N(C2H5)H2; by heating the mono and the diamines with more iodide of ethyl, diethylamine, N(C2H3)2H, and triethylamine, N(C2H5)3, are obtained. Triethylamine unites directly with iodide of ethyl, forming N(C2H5)3. C2H5I, triethylamine ethyl iodide. This compound, heated with silver oxide and water, forms N(C2H5)3. C2H5OH, a strong base, which is solid, like caustic potash. The H atoms can be replaced by different alcohol radicals, as methyl-ethyl-amyl a mine, N (CH3) (C2H3) (C5H11). The I can be also replaced by metals, as mono pota a mine, NIIK, and tri pota a mine, NK3. The amines have a strong alkaline reaction like ammonia, and unite with acids to form salts. *ăm-is. [AMICE.]
