| 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. |

| Abstract: |
| 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. |
