-
Paragraph 0073-0074, (2021/11/14)
The invention provides a catalytic synthesis of acrylamide compounds with zirconium-based ternary oxide solid acid as a catalyst, and the low-temperature activity is good. In the synthesis process, the acid is small, the reaction conditions are mild and controllable, the byproducts are few, the reaction yield is effectively improved, the purity is high, the quality is good, and the method is suitable for large-scale production.

A task-specific ionic liquid, 1,8-diazabicyclo[5.4.0]-undec-7-en-8-ium acetate has been successfully used as a catalyst for aza-conjugate addition of aliphatic or aromatic amines to various electron deficient alkenes under solvent-free conditions and at room temperature. The catalyst can be reused for six times without noticeable loss of activity.
