摘要: 以1,3-二(氯丙基)四甲基二硅氧烷和八甲基环四硅氧烷为原料在浓盐酸催化下制成α,ω-二氯丙基聚硅氧烷,再与N-甲基咪唑反应合成Bola型咪唑离子液体基有机硅表面活性剂。对产物结构进行了核磁共振氢谱(1HNMR)、傅里叶红外光谱(FTIR)和差示扫描量热分析(DSC)表征,并进行了表面张力测定,结果表明:与烷基类Bola型表面活性剂相比,Bola型咪唑离子液体基有机硅表面活性剂具有更好的表面活性,第一临界胶束浓度(cmc)为0.13 g/L、第二cmc为7.92 g/L,最低表面张力(γcmc)为24.3 mN/m。

Abstract: A novel Bola-type ionic liquid based silicone surfactant was prepared by the reaction of α,ω-bis(chloropropyl) polysiloxane and N-methylimidazole.The former was prepared with 1,3-bis(chloropropyl)tetramethyl-disiloxane and octamethylcyclotetrasiloxane as starting materials under the catalytic action of concentrate hydrochloric acid.Chemical structure of the product was characterized by 1HNMR,FTIR and DSC.Its critical micelle concentration (cmc) and surface tension at cmc (γcmc) was measured.The first cmc is 0.13 g/L.The second cmc is 7.92 g/L,and γcmc is 24.3 mN/m.

Key words: silicone surfactant, ionic liquids, Bola type, synthesis, surface activity
