Procedure

Friedrich in an article entitled "Oxidation of Methyl Formylstearate with Molecular Oxygen" at J. Am. Oil Chemists' Soc. 53, p. 125-129 (1976) reports the use of air or oxygen to form methyl carboxystearate from methyl formylstearate in an emulsion with a soluble rhodium complex. The reuse of catalyst in hydroformylation reactions is described by Awl in an article entitled "Hydroformylation with Recycled Rhodium Catalyst and One-Step Esterification-Acetalation: A Process for Methyl 9(10)-Methoxymethylenestearate from Oleic Acid" which is printed in J. Am. Oil Chemists' Soc. 53, p. 190-195 (1976).
