Paragraph 0032-0040, (2021/05/28)
PROBLEM TO BE SOLVED: To provide an industrially useful method for producing a (meth)acrylic acid anhydride capable of producing a (meth)acrylic acid anhydride with high yield and high purity. SOLUTION: There is provided a method for producing a (meth)acrylic acid anhydride by reacting a (meth)acrylic acid alkali metal salt and sulfonyl chloride in an organic solvent. The (meth)acrylic acid alkali metal salt includes lithium (meth)acrylate, sodium (meth)acrylate, potassium (meth)acrylate or the like. Among these (meth)acrylic acid alkali metal salts, preferable are sodium acrylate, potassium acrylate, sodium methacrylate and potassium methacrylate in consideration of market feedability, reactivity and easiness of treatment after the reaction. In addition, the sulfonyl chloride includes benzenesulfonyl chloride, p-toluenesulfonyl chloride and methanesulfonyl chloride. SELECTED DRAWING: None COPYRIGHT: (C)2021,JPOandINPIT

Paragraph 0019; 0020; 0021, (2017/10/07)
The invention discloses a method for preparing N-hydroxyethylmethacrylamide. Methacrylic anhydride moderately reacts with aminoethanol under low temperature. A generated byproduct methacrylic acid can be separated from a product through a distillation manner, and a production process is simple and feasible. The N-hydroxyethylmethacrylamide obtained by the method disclosed by the invention has high purity and high yield.
