合成了几种具有刚性连接基团的双子表面活性剂 ,研究了它们在 Rh-TPPTS体系中催化长链烯烃氢甲酰化反应中的助催化作用 .结果表明 ,在水 /有机两相催化体系中 ,新型双子表面活性剂的助催化作用比单链表面活性剂 CTAB更好 ,在较低的表面活性剂浓度下能得到较高的反应转化率 .这归因于此类表面活性剂有较低的 cmc,降低界面张力的能力和对 1 -十二烯的增溶能力比 CTAB更强 Several gemini surfactants with rigid linking groups were synthesized and their catalytic activities in the hydroformylation of long-chain olefins in Rh-TPPTS system were studied.The results showed that in the aqueous / organic two-phase catalytic system , The new gemini surfactant has better cocatalytic activity than the single-chain surfactant CTAB and higher conversion of the reaction at lower surfactant concentration due to the more surfactant Low cmc, ability to reduce interfacial tension and stronger solubilization of 1-dodecene than CTAB
