REACTION OF ALDEHYDES OF THE FURAN SERIES. 2. OXIDATION WITH SODIUM HYPOHALITES

Article abstract of DOI:10.1007/BF00506357

The condition for the oxidation of formylfurans with sodium hypobromite and hypochlorite that promote an increase in the yields for the furancarboxylic acids were investigated.The usual composition of the hypohalite mixture : = 3 gives low yields of the furancarboxylic acids, particularly on the basis of 5-methylfurfural.Doubling the relative percentage of alkali promotes an increase in the efficiency of the reaction.An interpretation of the process is given.
