Synthesis of anionic Gemini silicone surfactant
摘要
Abstract
With γ- aminopropyl diethoxy methyisilane, hexamethyldisiloxane, methyl acrylate, glutaryl chlo⁃ride as the raw material, Gemini silicone surfactant was synthesized by the addition, amidation and hydrolysis reaction. The influences of the ratios of intermeidate Ⅱ and glutaryl chloride, reaction time and reaction tem⁃perature on the yield of the intermediate Ⅲ were investigated. The optimum reaction conditions were n(the in⁃termediate Ⅱ)∶n(glutaryl chloride)=2.1∶1.0, reaction temperature was 35 ℃, and reaction time was 6 h. The yield of the intermediate Ⅲ was 83.29%. Surface tension of Gemini silicone surfactant was 26.94 mN/m, and the critical micel e concentration was 5.0×10- 4 mol/L at 25℃, and its foaming performance was relatively low.关键词
