Synthesis and performance of CO2 switchable amine surfactants
摘要
Abstract
Surfactant tetradecyldiethylenetriamine (C 14 DETA)was synthesized with 1-bromotetradecane and diethylenetriamine as starting materials.Its structure was characterized by FT-IR and 1 H NMR spectrum.Measurement of reversibility of conductivity,reversibility of pH values,and the opening action of synergistic effect with SDS demonstrate the good CO2 switchability of C14 DETA.The critical micelle concentrations (cmc) of tetradecyldiethylenetriamine bicarbonate (C 14 DETA-CO2 )and the mixed system of SDS/C 14 DETA-CO2 are 1.0×102 and 1.0×10-4 mol/ L respectively.Results of emulsifying performance of C14 DETA-CO2 for n-decane/water system prove the good emulsifying power of C14 DETA-CO2 .The emulsion is water-in-oil type,and its better emulsifying conditions are:mass fraction of C 14 DETA-CO2 ,4%;and the volume ratio of oil/ water,1:1 or 1:2.关键词
