Synthesis of Quaternary Ammonium Salt Cationic Surfactant with Long-Chain Alkyl and Epoxy Groups

Abstract:

The quaternary ammonium salt cationic surfactant with long-chain alkyl and epoxy groups is very important intermediate product to synthesis novel functional surfactants. In this paper, a kind of quaternary ammonium salt cationic surfactant with long-chain alkyl and epoxy groups was synthesized by traditional method with epichlorohydrin and N-octadecyldimethylamine as raw materials. During the synthesis, the best reaction conditions have been obtained, that the reaction temperature is 35 °C, the reaction time is 4 h and the best mol ratio of epichlorohydrin to timethylamine is 5:1. In addition, the synthesized intermediate with long-chain alkyl and epoxy groups plays a very important roles in the development of cationic surfactant.
