Abstract
High molecular olefines are prepared by heating secondary amines having at least one aliphatic chain of more than eight carbon atoms, until the amino group is eliminated, with compounds of an acid nature which form salts with amines. In examples: (1) heptadecylphenylamine is heated in a stream of hydrogen chloride; heptadecylene and heptadecylchloride distil over and the latter may be converted with heptadecylene by removal of hydrogen chloride; (2) undecylphenylamine is heated with zinc chloride to give pure undecylene. Pentadecylphenylamine, ethylheptadecylamine and diheptadecylmethylenephenylamine are specified as starting materials. Undecylphenylamine, ethylheptadecylamine and diheptadecylmethylenephenylamine may be prepared by removal of carbon dioxide from anilinolauric acid, ethylaminostearic acid and diheptadecylanilinoacetic acid respectively. The latter may be prepared by reacting aniline with diheptadecylbromacetic acid which may be obtained by saponification of diheptadecylbromacetylbromide.
