Improvements in manufacture of formaldehyde condensation products of aliphatic amines and products obtained thereby

摘要

Trialkyltrimethylenetriamines or their polymers are obtained in the form of their salts with halide acids by condensing hexamethylenetetramine or a solution of formaldehyde and ammonia with alkyl halides. The products are oils or resins according to their degree of polymerization. Examples show the condensation of hexamethylenetetramine or a solution of formaldehyde and ammonia with ethyl chloride, methyl iodide, butyl iodide, and a mixture of ethyl iodide and bromide by heating the reagents under pressure. In each case the free base may be liberated by treatment with caustic soda.
