摘要: CONSTRUCTION The present invention relates to an industrial purification process in the process of manufacturing alcohols and ketones by oxidation of hydrocarbon wherein after removing by extraction organic impurities, formed as by-products of an oxidation reaction, from aqueous boric acid solution obtained by hydrolysis of an oxidation reaction solution containing boric acid ester, obtained by performing an oxidation reaction in the presence of boric acid, in order to essentially regenerate boric acid and prevent lowering of the reaction rate, selectivity and excessive soiling of the apparatus in the case of cyclically using said regenerated boric acid in an oxidation reaction, boric acid is regenerated and cyclically used again in said hydrocarbon oxidation reaction.EFFECTThe present invention is a process for purifying boric acid for hydrocarbon oxidation which reduces the amount of harmful impurities to an extent that allows circulating aqueous boric acid solution to be reused in a continuing oxidation reaction, while also maintaining the selectivity of the oxidation reaction at a level of selectivity obtained with fresh boric acid.
