| titleOfInvention | A kind of serialization preparation facilities of N-pyrrolidone acetate |
| abstract | The utility model discloses a kind of serialization preparation facilities of N-pyrrolidone acetate, this preparation facilities comprises: material mixer (1), tubular type salt-forming reactor (2), reactive distillation column (3), supplementary solvent mixing tank (4), tubular type condensation reactor (5), equipment room connection line, control instruments and annex; Material mixer (1), tubular type salt-forming reactor (2), to supplement solvent mixing tank (4), tubular type condensation reactor (5) be tube type apparatus with or without chuck, and arranging in pipe or not arranging has moving and static mixing element of disturbance mixing effect to material.It is that starting raw material prepares salify in Piracetam (piracetam) technique, condensation reaction N-pyrrolidone acetate realizes serialization and prepares that the utility model can make by pyrrolidone.Mass transfer effect is good, and fully, speed of response is fast in material contact; Heat-transfer effect is good, and temperature of reaction controls precisely, to be conducive to improving the quality of products. |
