Abstract
A complex formed by combining cobalt carbonyl with one member selected from the group consisting of pyridine, alkylpyridine and formylalkylpyridine makes a catalyst exceptionally suitable for both hydroformylation and hydroesterification of olefins, whereas a complex formed by combining cobalt carbonyl, pyridine and ketone makes a catalyst exceptionally suitable for hydroesterification of olefins. The conditions required for the manufacture of this catalyst are included in the conditions for hydroformylation or those for hydroesterification. The formation of this catalyst and the hydroformylation or hydroesterification involving the use of said catalyst can be carried out continuously in a cyclic pattern.
