| titleOfInvention | Catalysis-based amino acetylation method |
| abstract | The invention discloses a catalysis-based amino acetylation method. The catalysis-based amino acetylation method utilizes Lewis alkali ionic liquid [HDBU]OAc as a catalyst, acetic anhydride as an acetylation agent, and an alicyclic amine or an aromatic amine as a substrate. The catalysis-based amino acetylation method comprises the following steps that 1, the substrate undergoes an acetylation reaction in the dis-presence of a solvent at a temperature of 40 to 80 DEG C for 0.3 to 1.5 hours, wherein a mole ratio of acetic anhydride to the substrate is (1.0 to 2.0): 1 and a mole ratio of Lewis alkali ionic liquid [HDBU]OAc to the substrate is in a range of 10 to 30%; 2, after the acetylation reaction, ether is added into the products; 3, the mixture obtained by the step 2 is filtered and separated; 4, the supernatant extract obtained by the step 3 is washed orderly through a saturated NaHCO3 solution and water; 5, the washed supernatant extract is added with waterless Na2SO4 for drying; and 6, the ether is removed by reduced pressure rotary distillation so that a finished product is obtained. The catalysis-based amino acetylation method has the characteristics of wild reaction conditions, high yield, low cost, environmental benefits and high safety. |
