摘要
合成了四种季铵盐型阳离子表面活性剂C22H45N(CH3)2C2H5Br(二十二烷基乙基二甲基溴化铵),C22H45N(CH3)2C4H9Br(二十二烷基丁基二甲基溴化铵),C22H45N(CH3)2C8H17Br(二十二烷基辛基二甲基溴化铵),C22H45N(CH3)2C12H25Br(二十二烷基十二烷基二甲基溴化铵),并考察了其对Rh-TPPTS[TPPTS:P(m C6H4SO3Na)3]催化的水 有机两相长链烯烃氢甲酰化反应性能的影响.研究结果表明,在该体系中添加含有疏水长链的阳离子表面活性剂后,反应性能得到明显改善.
The four cationic surfactants, C 22 H 45 N(CH 3 ) 2 C 2 H 5 Br,C 22 H 45 N(CH 3 ) 2 C 4 H 9 Br, C 22 H 45 N(CH 3 ) 2 C 8 H 17 Br , C 22 H 45 N(CH 3 ) 2 C 12 H 25 Br were synthesized, and their effect on different olefins hydroformylation catalyzed by Rh TPPTS was investigated in aqueous two phase catalytic system. The results indicated that longer lipophilic chain was favored to accelerate the reaction rate of the hydroformylation.
