| titleOfInvention | A kind of method for preparing hydroxyalkylamide by extruder |
| abstract | The invention discloses a method for preparing a hydroxyalkyl amide by an extruder. The hydroxyalkyl amide is prepared by a reactive extrusion method, and specifically includes the following steps: β-alkanolamine, dimethyl adipate, Antioxidant and catalyst are added into the mixing kettle, and at about 60-70 ℃, stirring and mixing for about 30min-1h, the material is thick; At the same time, vacuuming is carried out, and the material is extruded and reacted by an extruder to form a flake, and then cooled and pulverized to obtain a white powder. The present invention uses β-alkanol ammonia and dimethyl adipate as raw materials, and prepares the β-hydroxyalkyl amide through an extruder extrusion method, which can not only greatly improve the reaction rate and production efficiency, but also has convenient operation and side reactions. less, high yield and low production cost. |
