| titleOfInvention | A kind of device for reducing the consumption of N-methylpyrrolidone reaction monomethylamine |
| abstract | The utility model discloses a device for reducing the amount of methylamine used in the N-methylpyrrolidone reaction, which relates to the technical field of N-methylpyrrolidone preparation, including an N-methylpyrrolidone reaction box, the N-methylpyrrolidone reaction box The top of the N-methylpyrrolidone reaction box is provided with a stirring device, the left side of the upper surface of the N-methylpyrrolidone reaction box is provided with a feed port, and the bottom of the left side of the outer wall of the N-methylpyrrolidone reaction box is fixedly connected with a discharge port. The utility model drives the stirring blade to rotate through the action of the motor, thereby stirring the solution in the N-methylpyrrolidone reaction box, accelerating the mixing of the solution in the N-methylpyrrolidone reaction box, and a stirring blade is arranged inside the stirring blade support. The fan blade, through the rotation of the stirring blade, drives the flow of the solution in the N-methylpyrrolidone reaction box, and drives the stirring fan blade to rotate under the action of the flowing solution, thereby stirring the solution again, so that the N-methylpyrrolidone reaction box is stirred again. The solution is fully fused. |
