    Abstract: A catalyst composition useful for the oxidation of olefins, particularly the oxidation of propylene and isobutylene to produce the corresponding unsaturated aldehydes acrolein and methacrolein, respectively, comprises the combination of oxides of molybdenum, cobalt, iron, bismuth, thallium and antimony, and preferably also silicon. When the catalyst is used for the vapor-phase oxidation of the olefins with molecular oxygen, the aldehydes are produced with high selectivity. Alcohol precursors for the olefins can be used as feed instead of the olefins themselves.

    Abstract: Esters of C2-C3 vicinal glycols with C1-C5 hydrocarbon carboxylic acids are at least partially freed from organic halogen compound impurities by introducing the impuritycontaining glycol esters into contact with compounds of selected metals, the ratio of total equivalents of metal to total equivalents of halogen during such contact being in excess of 1: 1. Following such contact, the vicinal glycol ester possesses a reduced concentration of organo-halogen compound impurities and can readily be separated from inorganic halogen residues.
