| titleOfInvention | A kind of energy-saving and high-efficiency synthesis process of acetylacetone |
| abstract | The invention discloses an energy-saving and high-efficiency synthesis process for acetylacetone, which comprises the following steps: (a) cracking acetic acid to generate ketene; (b) introducing and pre-storing ketene; (c) mixing and stirring acetone and a catalyst; (d) ketene React with acetone; (e) feed pre-stored ketene into the reaction furnace; (f) obtain crude acetylacetone; (g) refine crude acetylacetone. In the invention, the stored diketene is decomposed into ketene, and then the ketene gas is directly introduced into the reaction furnace to supplement the ketene gas in the reaction furnace, and the ketene generated by the cracking of acetic acid is directly introduced into the reaction furnace, and the acetone is directly injected into the reaction furnace. The reaction furnace can improve the continuity of the reaction in the reaction furnace and improve the reaction efficiency; in addition, the sulfuric acid catalyst is mixed into the acetone solution, and the catalyst is added in three stages with stirring blades, which can strengthen the uniform distribution of the catalyst, so that the acetone and the catalyst are mixed evenly, Increase the yield of acetylacetone. |
