Title: PROCESS FOR PRODUCING ALDEHYDE
Abstract:
A process for producing aldehyde by reacting an olefinic compound with carbon monoxide and hydrogen in a catalyst solution containing a rhodium compound and a tertiary phosphine, which process comprises using as the tertiary phosphine a diphenylphosphino group-containing styrene oligomer having 5 to 100 mol % of a structural unit represented by the following formula:$(6,)$and having a fundamental skeletal styrene oligomer of number-average polymerization degree of 3 to 350, controlling the amount of the phosphorus atom in the diphenylphosphino group-containing styrene oligomer in the range of at least 5 mols per mol of the rhodium atom in the catalyst solution, and conducting the reaction under such a condition that the catalyst solution is in a substantially uniform system.
