The kinetics of hydroformylation of 1‐decene has been studied in an aqueous biphasic medium using a water‐soluble Rh‐sulfoxantphos catalyst in the presence of N‐methyl pyrrolidone as a cosolvent at 383‐403 K. The rate was found to be first order, with concentrations of catalyst and olefin and partial order, with concentrations of hydrogen in the liquid phase. The plot of rate versus excess ligand and CO concentrations passed through maxima, indicating negative order dependence at higher concentrations. These trends have been interpreted based on the established hydroformylation mechanism. High selectivity towards the linear aldehyde was maintained (n: iso ratio > 30). An empirical rate equation has been proposed which was found to be in good agreement with the observed rate data within the experimental error. The activation energy was evaluated to be 74.76 kJ/mol.

在助溶剂存在下使用水溶性Rh-sulfoxantphos催化剂在水性双相介质中1-癸烯加氢甲酰化的动力学

已经在存在氮的情况下使用水溶性Rh-sulfoxantphos催化剂在水性双相介质中研究了1-癸烯的加氢甲酰化动力学甲基吡咯烷酮在383-403 K时作为助溶剂。发现该速率为一阶，其中催化剂和烯烃的浓度为一阶，而液相中氢的浓度为一阶。速率与过量配体和CO浓度的关系曲线通过最大值，表明在较高浓度下负序依赖性。这些趋势已基于已建立的加氢甲酰化机理进行了解释。保持了对线性醛的高选择性（n：iso比> 30）。已经提出了经验速率方程，其发现与实验误差内的观测速率数据非常吻合。活化能评估为74.76 kJ / mol。
