Abstract
PURPOSE: To prepare the titled compound by chlorinating an alkanolamine with hydrochloric acid or hydrogen chlride gas keeping the molar ratio of water existing finally in the system to the chloroalkylamine hydrochloride below a specific level.
CONSTITUTION: In the preparation of a chloroalkylamine hydrochloride of formula II (R1WR4 are H or alkyl; n is 2W4) by the chlorination of an alkanolamine of formulaI, the reaction system is made essentially free from water when the content of the chloroalkylamine hydrochloride of formula II in the system reaches at least 40mol%, and then the chlorination of the unreacted alkanolamine in the system is further proceeded using hydrogen chloride gas as the chlorination agent.
EFFECT: The reaction can be carried out without using expensive and dangerous thionyl chloride nor using high temperature and pressure.
USE: An aminoalkylating agent. Intermediate of pesticides, pharmaceuticals, dyes, pigments, etc. Raw material of polymers, etc.
