Oxidative dehydrogenation of glycolic acid to glyoxylic acid over Fe-P-O catalyst

Article abstract of DOI:10.1246/cl.1996.917

Glyoxylic acid was obtained by a vapor phase oxidative dehydrogenation of glycolic acid over an iron phosphate catalyst with a P/Fe atomic ratio of 1.2. The one-pass yield reached 59 mol% at the glycolic acid conversion of 78%; the selectivity of 76 mol%.
