A catalyst, useful for the hydroformylation of allyl alcohol, is described. The catalyst comprises a rhodium complex and a 6-bis(3,5-dialkylphenyl)phosphino-N-pivaloyl-2-aminopyridine or a 3-bis(3,5-dialkylphenyl)phosphino-2H-isoquinolin-1-one. The invention also includes a process for the production of 4-hydroxybutyraldehyde comprising reacting allyl alcohol with a mixture of carbon monoxide and hydrogen in the presence of a solvent and the catalyst. The process gives a high ratio of the linear product 4-hydroxybutyraldehyde to the branched co-product 3-hydroxy-2-methylpropionaldehyde.
描述了一种用于烯丙醇水合甲醛化的催化剂。该催化剂包括一个铑络合物和一种6-双(3,5-二烷基苯基)磷酰-N-戊酰基-2-氨基吡啶或一种3-双(3,5-二烷基苯基)磷酰基-2H-异喹啉-1-酮。该发明还包括一种生产4-羟基丁醛的方法,包括在溶剂和催化剂的存在下,将烯丙醇与一种一氧化碳和氢的混合物反应。该过程提供了线性产物4-羟基丁醛与支链共产物3-羟基-2-甲基丙醛的高比例。
