| titleOfInvention | The preparation method of N-methylmorpholine |
| abstract | The invention discloses a kind of preparation method of N-methylmorpholine: using atmospheric fixed bed reactor as reaction unit, loaded catalyst is set in atmospheric fixed bed reactor; With the mixture of morpholine and methyl-formiate for raw material, the mol ratio of described methyl-formiate and morpholine is 0.5 ~ 0.9:1; By the fixed-bed reactor containing loaded catalyst after material gasification, under hydro condition, carry out amination reaction; Reaction pressure is 0.12 ~ 0.19MPa, temperature is 120 ~ 130 DEG C; The volume space velocity V of reaction is 0.05 ~ 0.3g/h/mL; After above-mentioned reaction terminates, after condensation, collect reactant, then after dehydration, rectifying, obtain N-methylmorpholine; The preparation process of loaded catalyst is as follows: utilize metal salt solution and carrier to make loaded catalyst, in described loaded catalyst, metal accounts for 22% ~ 32% of gross weight, and metal-salt is mantoquita and zinc salt. |
