ABSTRACT:
Full esters of polyols selected from pentaerythritol and polypentaerythritols are continuously produced by (i) continuously introducing a solution of the polyols in pyridine bases, olefins having at least 4 carbon atoms in an amount of at least 0.4 equivalent per 1.0 equivalent of the hydroxyl group in the polyols, a catalyst containing cobalt carbonyls and pyridine bases, and carbon monoxide, into a reaction zone from one end thereof in such an amount of the pyridine bases as is within the range of from 40 to 70% by weight based on the total amount of the pyridine bases, the polyols and the olefins; (ii) introducing an additional amount of the olefins into at least one middle portion of the reaction zone, and; (iii) continuously withdrawing the resultant reaction mixture from the other end of the reaction zone.
