丁烯氢甲酰化制备低正异比混合戊醛新型催化剂开发及反应动力学的研究

将自主开发的低正异比（N/I）氢甲酰化催化（HY-IH）体系用于丁烯氢甲酰化合成制戊醛.通过小试工艺优化,2-甲基丁醛选择性大于50%（即N/I约为1∶1）,远高于国内现有工业装置3%~10%的水平.同时,得到反应速率与丁烯浓度、反应温度和催化剂铑（Rh）浓度的相关动力学方程.通过连续模试反应对小试动力学进行了修正,为工业化装置设计提供了依据.

Development of a new catalyst for 1-butene hydroformylation to low N/I ratio mixed valeraldehyde and study on reaction kinetics

A self-developed low normal/isomer ratio(N/I) hydroformylation catalyst (HY-IH) was used for 1-butene hydroformylation to low N/I ratio mixed valeraldehyde. Through the process optimization of small-scale test,the selectivity to isovaleraldehyde is more than 50% (i.e.,the N/I ratio is about 1:1),which is much higher than the existing domestic industry parameter (3%-10%). At the same time,the kinetic equation related to 1-butene concentration,reaction temperature,and rhodium(Rh) concentration was deduced. The kinetics of small-scale test was modified by continuous reaction of pilot plant test,which provided a basis for the design of industrial plant.
