Paragraph 0039; 0040, (2018/09/08)
The invention discloses a synthesis and refining method of N-alkyl acrylamide. The synthesis and refining method comprises the following steps: enabling acyl chloride and primary amine to have amination in a solvent A, washing a reaction product, absorbing impurities, decoloring, cooling, and crystallizing to obtain a crude product, recrystallizing the crude product by using a solvent B, decompressing and drying to obtain a target product. By adopting the synthesis and refining method, the conversion rate of acryloyl chloride is 85 percent or more, and the product purity is 98.5 percent or more.
