Abstract: Hydroxycarboxylic acids, e.g., 3-hydroxypropionic acid, and/or their ammonium salts are dehydrated to their corresponding unsaturated carboxylic acids, e.g., acrylic acid, by a process that uses a catalyst comprising ammonium bisulfate. The use of ammonium bisulfate reduces or eliminates the problems associated with processes that use sulfuric acid as a dehydrating catalyst, e.g, excess sulfuric acid consumption and/or recovery.
Abstract translation: 通过使用包含硫酸氢铵的催化剂的方法将羟基羧酸例如3-羟基丙酸和/或其铵盐脱水成相应的不饱和羧酸，例如丙烯酸。 使用硫酸氢铵减少或消除了与使用硫酸作为脱水催化剂的方法相关的问题，例如过量的硫酸消耗和/或回收。
