摘　　要：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.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.
