Reaction between Oleylalcohol and Triethylamine

Abstract

In order to obtain higher alkyldiethylamines, which are used as the raw material of various cationic surfactants, reaction between oleylalcohol and triethylamine was carried out using Cu-Cr-O (modified by MnO₂) catalyst under moderate pressure.
The reaction conditions which gave the best yield of 76% were following :
Mole ratio of oleylalcohol : triethylamine= 1 : 5
Weight % of the catalyst to alcohol : 15%
Initial hydrogen pressure : 20 kg/cm2
Max. reaction pressure : ca. 45 kg/cm2
Reaction temperature : 250
Reaction time : 3 hr
Catalyst and triethylamine reoveries were also inveatigated and obtained good results.
