Ethyl Benzyl Quaternary Amines of Amido Amines for Improved Antifungal properties

Abstract

Ethylbenzyl chloride quats (EB quats) and their related salts. The synthesis of EB quats requires minimal capital requirements, produces products in good yields, without difficult to dispose of waste and in a cost-effective manner. The preferred embodiment of the invention is to perform a condensation reaction of a linear or branched, saturated or unsaturated fatty acid, of between 2 and 22 carbons with an amine that has either a primary amine and tertiary amine or a secondary amine and tertiary amine. An example is dimethylaminopropylamine (DMAPA). The amido amine that results from the condensation reaction described is then reacted with ethyl benzyl chloride (EBC) to produce the desired EB quat. Additional processing, such as ion exchange can be performed to eliminate the chlorine or substitute it for another anionic species, organic or inorganic.
