    Abstract: A method of producing an unsaturated acid from a salt of a hydroxycarboxylic acid, the method includes providing an aqueous solution including a salt of a hydroxycarboxylic acid; adding a solvent with a boiling point of 200° C. or higher to the aqueous solution; and heating the aqueous solution at a temperature lower than the boiling point of the solvent to split a salt from the salt of the hydroxycarboxylic acid while simultaneously dehydrating the hydroxycarboxylic acid, thereby converting the hydroxycarboxylic acid to the unsaturated acid.

    Abstract translation: 一种由羟基羧酸的盐生产不饱和酸的方法,该方法包括提供包含羟基羧酸盐的水溶液; 向该水溶液中加入沸点为200℃以上的溶剂; 并在低于溶剂沸点的温度下加热水溶液,以从羟基羧酸的盐中分离出盐,同时使羟基羧酸脱水,从而将羟基羧酸转化成不饱和酸。
