The present invention provides a solventless process for the catalytic hydrogenation of esters of 4,4,4-trihaloacetoacetic acid using a platinum catalyst in the presence of an acid or base co-catalyst to provide the analagous 3-hydroxybutyrate ester. Such 3-hydroxybutyrate esters are useful as solvents, cleaners or fine chemical intermediates.
