Abstract:
To develop a green and mild synthetic process of hydroxyl octadecadienoic acid，the reduction of hydroperoxy octadecadienoic acid with Na2SO3in aqueous solution to produce hydroxyl octadecadienoic acid was studied，using hydroperoxy octadecadienoic acid as the starting material that was prepared by oxidation of linoleic acid with soybean lipoxygenase as the catalyst.Two protocols were employed to enhance the solubility of the reactants and therefore to improve the product yield.Ethanol was used as the co-solvent，and Na2CO3was used to saponify hydroperoxy octadecadienoic acid partially.The reaction parameters were optimized.The conversion of hydroperoxy octadecadienoic acid obtained with both of the protocols were similar.The highest conversion of hydroperoxy octadecadienoic acid reached 98.5%.
