摘　　要：在烯烃氢甲酰化反应两相催化体系中，为提高催化剂活性及选择性，有采用外加无机盐的报道［１～３］．从这些文献可以看出，某些无机盐在反应中起到催化助剂的作用．我们曾经研究了硫酸钠及其它金属硫酸盐中的阳离子对反应的影响［４，５］．在引入这些阳离子的同时，还有...In this paper investigation of the influence of some anions on 1hexene hydroformylation in biphasic system catalyzed by RhCl(CO)(TPPTS)2TPPTSCTAB was represented . The results indicated that: 1)The effects of anions decrease with the order SO32->CO32-> S2O32-> S2O42-> Cl- >Br-> B4O72-> HCO3-> I-> EDTA2-> H2PO4- >SO42-, which was interpreted by their difference of complexing capability with rhodium and their influence on the pH value of water phase. 2)The influence of anion of the surfactant(cetyltrimethylammonium salt) could be ignored. These results give further support to the interaction mechanism of the metastable cationic micellerhodium complex anion pair in biphasic catalysis of olefin hydroformylation.
