摘要： 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 methylcyclohexane as a reaction solvent and a catalyst system comprising a rhodium complex and a substituted or unsubstituted diphosphine ligand. The use of the methylcyclohexane increases the reaction rate while also giving a high yield of 4-hydroxybutyraldehyde compared to 3-hydroxy- 2-methylpropionaldehyde and improving the separation of the hydroxy aldehyde products from the catalyst system.
