Abstract: Method for the preparation of ketones, by means of oxydation of the corresponding secondary alcohols, characterized in that said alcohols are catalytically oxidized by H.sub.2 O.sub.2 inside a two-phase system comprising:(a) an aqueous phase, containing hydrogen peroxide as the oxidizing agent;(b) an organic phase, containing a secondary alcohol and optionally a solvent immiscible with said aqueous phase, as well as a peroxidic catalyst having the general formula Q.sub.3 XW.sub.4 O.sub.24, wherein X represents an atom of phosphorus or of arsenic and wherein Q represents a quaternary cation, containing hydrocarbon groups having a total of from 20 to 70 C atoms.

Abstract: A process for the preparation of water-soluble vicinal diols by means of a direct catalytic hydroxylation of the corresponding olefines with H.sub.2 O.sub.2. An olefine possibly carrying functional groups inert under the reaction conditions, and whose corresponding vicinal diol is soluble in water, is made to react, under vigorous stirring, with H.sub.2 O.sub.2 at a temperature between 0.degree. and 120.degree. C. and at a pressure between 1 and 100 atmospheres, in a two-phase aqueous liquid/organic liquid system consisting or consisting essentially of an acid aqueous phase containing H.sub.2 O.sub.2 and of an organic phase containing (1) said olefine; (2) possibly a solvent immiscible with the aqueous phase; and (3) a catalyst of the formula:Q.sub.3 XW.sub.4 O.sub.24-2nwherein Q represents an onium (RR.sub.1 R.sub.2 R.sub.3 M).sup.+ cation, wherein M is chosen from among N, P, As and Sb, and R, R.sub.1, R.sub.2 and R.sub.
