Title: Production of aldehyde
Inventor: YOSHITOME SHUNEI
IPC: C07C47/02
Filed: 1986-03-27
Abstract: PURPOSE:To improve the thermal stability of a catalyst and to increase the yield of aldehyde in the hydroformylation of an olefin compound having vinyl group at a terminal in the presence of a rhodium complex compound, by adding a specific organic phosphorus compound to the reaction system. CONSTITUTION:An aldehyde is produced by the hydroformylation of an olefin compound having vinyl group at a terminal in an organic solvent in the presence of a rhodium complex compound (catalyst). The reaction is carried out in the presence of one or more organic phosphorus compounds selected from PRO(OH) H and (RO)2POH (R is alkyl or aryl) optionally in combination with a tertiary phosphine compound. The thermal stability of the catalyst can be improved, the lowering of olefin conversion caused by the repeated use of the catalyst can be prevented and undesirable isomerization reaction and hydrogenation reaction of olefin can be suppressed. Accordingly, the objective compound can be produced in high selectivity and yield with prolonged catalytic life.
