Amine Sentence Examples

  • It has to some extent the character of a secondary amine; the hydrogen of the imino group can be replaced by potassium.

  • The tertiary amine is then distilled off, the residual products separated by filtration and finally hydrolysed by a caustic alkali.

  • The secondary amines may be of two types-namely,the purely aromatic amines, and the mixed secondary amines, which contain an aromatic residue and an alkyl group. The purely aromatic amines result upon heating the primary amines with their hydrochlorides, and, in some cases, by heating a phenol with a primary amine and anhydrous zinc chloride.

  • The mixed secondary amines are prepared by the action of alkyl iodides on the primary amines, or by heating salts of the primary amine with alcohols under pressure.

  • The simplest aromatic tertiary amine, triphenylamine, is prepared by the action of brombenzene on sodium diphenylamine (C. Heydrich, Ber., 1885, 18, p. 2156).
