| titleOfInvention | Method for preparing acetone by using byproducts in triacetonamine synthesis process |
| abstract | The invention belongs to the technical field of acetone preparation, and particularly discloses a method for preparing acetone by using byproducts in a triacetonamine synthesis process. The main technical scheme comprises: pumping the byproducts generated in the process of synthesizing triacetonamine into a head tank; adding a catalyst and water into a reaction kettle; starting the reaction kettle, stirring, and heating the kettle to 60-100 ℃; dropwise adding the by-product into the reaction kettle from the elevated tank; opening a condenser to cool water, and collecting regenerated acetone in a storage tank; after the reaction is finished, the regenerated acetone is directly put into a main production line of triacetonamine as a synthetic raw material, and the next batch of regenerated acetone operation is carried out after water is supplemented in the reaction kettle. The acetone is prepared by taking the by-product generated in the triacetonamine synthesis process as the raw material, so that the utilization value of the by-product is improved, and the yield of the triacetonamine synthesized by taking the acetone as the raw material is improved in the view of the whole process. |
