The cobalt/pyridine catalyzed hydroesterification of olefine has been investigated in detail. In this paper a catalyst system of a nitrogen|containing heterocyclic compound having an enolic hydroxy group on the carbon atom adjacent to the ring forming nitrogen atom with a cobalt carbonyl compound was studied in carbonylation of 1|heptene. Under the reaction conditions of T =100 ℃ and p =5.0 MPa for 6 h, it is obvious that the nitrogen|ring compound has accelerative effect on the hydroesterification of 1|heptene . Among the N|ring bases studied, hydroxy group|containing N|ring compound has been found to be most effective, but the conversion of 1|heptene decreased with the increase of the concentration of the N|compounds . The effectiveness of N|containing heterocyclic compound in increasing the conversion of heptene decreases in the order: 2|hydroxypyridine > 3|hydroxypyridine > quinoline> 8|hydroxyquinoline 3,5|lutidine > pyridine.
