| titleOfInvention | Novel method for preparing N-N-butylacrylamide |
| abstract | The invention relates to the technical field of fine chemical engineering, and discloses a novel method for preparing N-N-butylacrylamide. The method comprises the following specific steps: the N-N-butyl-3-methylthiopropanamide as a starting material and an additive Selectfluor (1-chloromethyl-4-fluoro-1, 4-diazabicyclooctane bis (tetrafluoroborate)) are stirred and react for 8 hours at 100 ℃ in an organic solvent 1, 4-dioxane to obtain the N-N-butyl acrylamide. The invention has the following characteristics: the N-N-butyl acrylamide can be obtained by directly heating and stirring fluorine as an additive. Compared with the prior art, the method does not need to use toxic, easily-corroded and easily-volatilized acyl chloride as a raw material, is simple to operate and has small influence on the environment. |
