Synthesis and Surface Activities of A Novel Cationic Surfactant of Triethyl Ammonium Chloride |
| |
| Abstract: | In order to realize the reasonable utilization and eliminate the harm of waste oil, waste oil was used to synthesize a novel cationic surfactant ( 4 ) through hydrolysis, open loop esterification of epichlorohydrin, and quaternization of triethylamin.The structure was characterized by 1 H NMR and IR.The interfacial properties were investigated.The results showed that he critical micelle concentra-tion of 4 was 4.16 ×10 -3 mol· L-1 , and theγcmc was 38.36 mN· m-1 .The foaming ability and foam stability of 4 was similar to n-hexadecyltrimethylammonium chloride. |
