For example, it is commonly used as a base during the preparation of esters and amides from acyl chlorides. Such reactions lead to the production of hydrogen chloride which combines with triethylamine to form the salt triethylamine hydrochloride, commonly called triethylammonium chloride. Hydrogen chloride may then evaporate from the reaction mixture, which drives the reaction. (R, R' = alkyl, aryl): naama hofman light objects
