A process for the production of 4-hydroxybutyraldehyde is described. The process comprises reacting allyl alcohol with a mixture of carbon monoxide and hydrogen in the presence of a solvent and a catalyst system comprising a rhodium complex and a 2,3-O-isopropylidene-2,3-dihydroxy-1,4-bis[bis(3,5-di-n-alkylphenyl)phosphino]butane. The process gives high yield of 4-hydroxybutyraldehyde compared to 3-hydroxy-2-methylpropionaldehyde.
描述了一种生产4-羟基丁醛的过程。该过程包括在溶剂和催化剂体系的存在下,将丙烯醇与一种混合物(一氧化碳和氢气)反应,催化剂体系包括一个铑络合物和一个2,3-O-异丙基亚甲基-2,3-二羟基-1,4-双[双(3,5-二烷基苯基)膦基]丁烷。该过程相比于3-羟基-2-甲基丙醛,能够产生高产率的4-羟基丁醛。
