Chromic acid adsorbed on silica gel

Chromic acid adsorbed on silica gel (Cr03 Si02 = 3 10) is a mild and safe reagent to oxidise saturated or unsaturated alcohols in carbon tetrachloride to the corresponding aldehydes. [Pg.1478]

Oxidation of Alcohols to Aldehydes and Ketones with Chromic Acid Adsorbed on Silica Gel [5J7]... [Pg.283]

Oxidation. Chromic acid adsorbed on silica gel is useful for oxidation of primary and secondary alcohols to carbonyl compounds. Yields are generally 80-907o- In contrast, H2CrOi adsorbed on alumina is ineffective. ... [Pg.60]
