OXIDATION AGENT FOR ALCOHOL AND OXIDATION USING THE SAME

摘要

PROBLEM TO BE SOLVED: To produce a corresponding carbonyl compound by oxidizing an alcohol with a halogen acid in high conversion and selectivity. SOLUTION: A primary or secondary alcohol is oxidized using an oxidizing agent comprising a halogen acid of the formula: M(XO3 )n (M is hydrogen atom or metal; X is a halogen atom; n is 1 or shows the valence of the metal M) or its salt (bromic acid, iodic acid or their alkali metal salt) and a reducing inorganic compound (sulfite, hydrogensulfite, thiosulfate or pyrosulfite) to give the corresponding carbonyl compound stoichiometrically. The oxidative esterification of a primary alcohol gives the corresponding ester and carboxylic acid, a secondary alcohol gives the corresponding ketone and anα,ω-diol gives the corresponding lactone or dicarboxylic acid.
