ABSTRACT:
Lactic acid is synthesized by a process in which a vinyl ester is hydroformylated to an .alpha.-substituted propionaldehyde by reacting the vinyl ester with carbon monoxide and hydrogen in the presence of a hydroformylation catalyst and by further converting the .alpha.-substituted carbonyl intermediate via oxidation and hydrolysis to lactic acid.
A preferred embodiment of the invention utilizes vinyl acetate as the feed.
