Problems solved by technology

[0002] In the past, the production process of aluminum acetylacetonate was formed by reacting benzene-containing substances with aluminum trichloride, and then polymerizing with acetylacetone. This method was difficult to control in the actual production process and the product was unstable.
In addition, the use of benzene substances will cause personal injury to operators, and a large amount of waste water will be generated, which will easily cause environmental pollution

Embodiment Construction

[0013] 1. Preparation:

[0014] Weigh 25kg of isopropanol, 10kg of pure aluminum powder, 45kg of acetylacetone, and 20kg of acetone.

[0015] 2. Production steps:

[0016] 1. Put isopropanol and acetone into the reaction kettle and raise the temperature to 50-60°C.

[0017] 2. Slowly add pure aluminum powder dropwise, and keep the temperature below 80°C until the reaction ends.

[0018] 3. Reflux for 30±10 minutes.

[0019] 4. Add acetylacetone dropwise to the reaction kettle, and keep the temperature below 80°C until the dropwise addition ends.

[0020] 5. Heat up to 100°C±10°C, then distill for 30-50 minutes, then cool to 40°C±5°C, and discharge.

[0021] 6. Centrifugally filter and dry to obtain 75kg of aluminum acetylacetonate.

Abstract

The present invention relates to a method for producing aluminium acetylacetonate. Said method includes the following steps: firstly, adding isopropanol and acetone into a reactor, heating to 50-60deg.C, then slowly drop-adding pure aluminium powder, controlling temperature below 80deg.C until the reaction is completed, making back flow for 30 plus on minus 10 min; then drop-adding acetylacetone in the reactor, controlling temperature below 80deg.C until the drop-adding procedure is completed, further heating to 100 plus or minus 10deg.C,5 refluxing for 30-50 min, cooling to 40 plus or minus 5deg.C, discharging material, centrifugalizing, filtering and drying so as to obtain the invented product.

Description

technical field [0001] The invention relates to a synthesis process of chemical products. Background technique [0002] In the past, the production process of aluminum acetylacetonate was formed by reacting benzene-containing substances with aluminum trichloride, and then polymerizing with acetylacetone. This method was difficult to control in the actual production process and the product was unstable. In addition, the use of benzene substances will cause personal injury to operators, and a large amount of waste water will be generated, which will easily cause environmental pollution. Contents of the invention [0003] The purpose of the present invention is to invent a production method of aluminum acetylacetonate without benzene, without pollutant discharge, easy to produce, and stable product quality. [0004] The present invention comprises the following steps: [0005] 1) Put isopropanol and acetone into the reaction kettle and heat up to 50-60°C; [0006] 2) Slowl...
