Abstract

PURPOSE: To separate for reuse catalyst without causing insolubles to crystallize after distillation of the subject products from reaction products obtained in the synthesis of alcohols from olefins over the Rh-tertiary amine catalyst.
CONSTITUTION: An olefinic unsaturated compound (for example, 1-hexene), in the presence of the Rh-tertiary amine catalyst (for example, Rh(CO)4Cl2. N-methyl- pyrrolindine), is reacted with an oxo gas, consisting of H2 and CO, charged by the addition of a solvent (for example, polyethylene glycol) of a higher boiling poing than that of the alcohol formed under the conditions of 20 to 300kg/cm2 and 50 to 200°C. Subsequently, from the reaction products, the subject alcohol (for example, heptyl alcohol) and N-methylphyrrolidine are separated by means of evaporation, and then the residual liquor containing catalyst is further made to perform oxo- reaction by the addition of an olefinic unsaturated compound and a tertiary amine in the same manner as the previous process. Thus, the alcohol can be recovered in high yield as in the previous process.
