摘　　要：考察了水溶性铑膦络合物RhCl(CO)(TPPTS)2(TPPTS为间-三苯基膦三磺酸钠)在水/有机两相体系中对不同单萜烯的氢甲酰化反应的催化性能.结果表明,添加表面活性剂对催化活性影响很大.在8.0 MPa,100℃的条件下,该催化体系对萜烯氢甲酰化反应具有较好的催化活性,月桂烯、莰烯和艹宁烯的转化率可分别达到92%,72%和86%.反应完成后,含水溶性铑膦络合物的水溶液与含产物的有机相分离方便,催化剂重复使用8次,其活性和选择性均未明显下降,易于实现催化剂的循环使用.The catalytic properties of water-soluble rhodium complex RhCl （CO） （TPPTS）2 [ TPPTS ： P （ mC6H4SO3Na）3] for monoterpenes hydroformylation in an aqueous/organic biphasic system have been investigated. The results showed that the activity for monoterpenes hydroformylation was accelerated by the addition of ionic surfactant. Under optimum reaction conditions, the conversion of myrcene, camphene, and limonene reached 92 %, 72 %, and 86 %, respectively. Furthermore, the rhodium catalyst immobilized in the water phase could be easily separated from the organic products and reused several times without significant loss of activity and selectivity. The rhodium leaching into the organic phase was lower than 0.04 % in each cycle.
