Abstract

The invention discloses a green preparation method of aluminum acetylacetonate in the technical field of fine chemical engineering. The green preparation method of the aluminum acetylacetonate comprises the following steps that step 1, a certain proportion of water is poured into a reaction kettle; step 2, a certain proportion of inorganic aluminum salt or boehmite is added while water is stirred,so that the inorganic aluminum salt or the boehmite is uniformly mixed with the water; step 3, a solution is heated to 60-90 DEG C while stirring; step 4, under a constant temperature state, a certain proportion of acetylacetone is added, and uniform stirring is carried out; step 5, during stirring, an acidic material is added into the solution, so that the PH value of the solution is 1.0-4.0; step 6, the solution in the reaction kettle is stirred for 1-3 hours at 60-90 DEG C. The green preparation method of the aluminum acetylacetonate has the advantages that the reaction rate between the inorganic aluminum salt or the boehmite and ethylene acetone is improved, the reaction between the inorganic aluminum salt or the boehmite and the ethylene acetone is relatively complete, residues are reduced, and the environmental protection property is improved.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to a green preparation method of aluminum acetylacetonate. Background technique [0002] Acetyl lactone is an important raw material of medicine, veterinary medicine, feed additive and catalyst, and is a widely used organic chemical intermediate. In China, 80% of acetylacetone is used in the production of sulfa drugs, such as sulfamethazine, sulfamethazine sodium and new varieties of sulfamethazine potassium. [0003] In addition to being used as a catalyst, aluminum acetylacetonate can also be used as a resin crosslinking agent, a resin hardening accelerator, a rubber additive, a superconducting film, a heat-reflecting glass film, a forming agent for a transparent conductive film, etc. In addition, it can also be used as an additive for gasoline and lubricating oil, as a drying agent for paints, coatings and printing inks, as an additive for adhesives, as a solvent for cell...
