Triethylbenzylammonium Chloride

Benzyltriethylammonium chloride is a lipophilic phase-transfer catalyst that can be used in phase-transfer catalysis (PTC) to catalyze polycondensation reactions to form high molecular weight polymers under bi-phasic conditions. It is used as a catalyst in the preparation of 2-phenylbutyronitrile from phenyl acetonitrile. It is involved in the Knoevenagel condensation of carbonyl compounds with active methylene compounds to give olefinic products. It acts as a phase transfer catalyst used in the alkylation reaction.

A preparation method of benzyltriethylammonium chloride, and belongs to the technical field of synthesis of the benzyltriethylammonium chloride. The method comprises the following steps: carrying out a quaternized addition reaction on triethylamine and benzyl chloride which are taken as raw materials by adding acetone taken as a solvent in reaction and dissolving processes; and dissolving, filtering and drying so as to the benzyltriethylammonium chloride.
