摘要
研究了水溶性膦铑配合物ＴＯＰＰ／ＲｈＣｌ３对１－十二烯水／有机两相氢甲酰化反应的催化性能。主要考察了反应温度、Ｐ／Ｒｈ摩尔比、水相ｐＨ值和溶剂等因素对催化活性和选择性的影响。在适当的反应条件下，得到了以十三酸为主的反应产物，这一结果至今未见文献报道。
In this paper, a new type of water-soluble phosphine P[p-C6H4O(CH2CH2O) n H]3(abbr. as TOPP) ligand was prepared and their rhodium complex, formed in situ, was used in biphasic system hydroformylation of 1-dodecene. The reaction temperature, P/Rh mole ratio, pH of aqueous phase and solvents showed great influence on the reaction. The carboxylic acid product was found for the first time, during the hydroformylation of 1-dodecene catalyzed by water-soluble phosphine rhodium complex (RhCl3/TOPP) in biphasic system.
