摘　　要：丙烯氢甲酰化单元是现阶段的丁辛醇主流生产装置工艺的核心部分,相比较于构成第二代低压羰基合成法核心的铑催化剂+三苯基膦体系,近年来开发成功的铑催化剂+新型双膦配体催化体系进一步提高了丙烯转化率,同时使得反应条件更加温和。主要研究了基于新型双膦配体催化体系,对既有丙烯氢甲酰化工艺进行优化,同时探讨了应用超重力反应技术以及适应不同正异比丁醛产物的工艺方案,为今后丁辛醇装置的工艺优化提供一种可借鉴的思路。The propylene hydroformylation unit is the core part pf the current mainstream production of butanol and octanol.Compared with the rhodium catalyst+triphenylphosphine system that constitutes the core of the second generation low pressure oxo synthesis,the rhodium catalyst+the new bisphosphine ligand catalytic system successfully developed in recent years further improves the conversion of propylene while making the reaction conditions milder.This paper mainly studies the optimization of the existing propylene hydroformylation process based on the new bisphosphine ligand catalytic system.At the same time,the application of hypergravity reaction technology and process plan to adapt to different n-isobutyraldehyde in the product were discussed,which provided a reference idea for the process optimization of the butanol-octanol plant in the future.
