研究了在水／有机物两相体系中水溶性钯－膦配合物催化柠檬醛的加氢反应．考察了反应温度、氢气压力、底物和催化剂浓度、反应时间、水相ｐＨ值等对该反应的影响，并与几种柠檬醛衍生物的加氢结果进行了比较．发现仅用蒸馏水作水相，则主要产物是二氢香茅醛（＞９３％）；而水相中加入Ｎａ２ＣＯ３后，则主要产物为香茅醛（９７％），且加氢速度比同样条件下使用Ｐｄ／Ｃ催化剂快得多．
The water-soluble palladium-phosphine complex was used to catalyze the hydrogenation of citral in water / organic two-phase system. The effects of reaction temperature, pressure of hydrogen, concentration of substrate and catalyst, reaction time and pH of aqueous phase on the reaction were investigated. The hydrogenation results of several citral derivatives were also compared. The main product is dihydron citronellal (> 93%). When Na2CO3 is added to the aqueous phase, the main product is citronellal (97%), and the hydrogenation rate is higher than that of the same condition The use of Pd / C catalysts is much faster.
