摘要

1445857 Hydroxyisobutyric acid ATLANTIC RICHFIELD CO 20 Nov 1973 [20 Nov 1972] 53789/73 Heading C2Cα-Hydroxyisobutyric acid is prepared by oxidizing isobutylene glycol with molecular oxygen in an aqueous solution with a pH in range 2-7 and in the presence of a catalyst. Supported noble metal catalysts, e.g. platinum or palladium on carbon or alumina may be used and a co-solvent such as dioxone may be present.
