Embodiment 1

[0028] Example 1: Reaction raw materials: acetylacetone 1600g (content 99.8%), calcium hydroxide 620g (content 99.2%), deionized water 1800g.

[0029] First, calcium hydroxide and deionized water are added to the reaction vessel 4 from the feeding port 6, and the stirring paddle 9 is turned on. After the calcium hydroxide and water are fully mixed into a thin paste, slowly add acetylacetone, continue to stir, and fully shear and stir After 2 hours of reaction. Close the reaction vessel, open the steam valve and the vacuum valve, and continue stirring and drying for 2 hours at a temperature of 50-80° C. under a negative pressure of 0-0.1 MPa. The water vapor is discharged from the gas outlet pipe 7, and after the drying is finished, the steam valve and the vacuum valve are closed. After the reaction and drying, the coarse powder was obtained, which was pulverized by a pulverizer to obtain 1871.69 g of calcium acetylacetonate (calculated as dry product), which should be 1900.19...

Embodiment 2

[0033] Example 2: Reaction raw materials: acetylacetone 2000g (content 99.7%), calcium hydroxide 769g (content 96.5%), deionized water 2000g.

[0034]First, calcium hydroxide and deionized water are added to the reaction vessel 4 from the feeding port 6, and the stirring paddle 9 is turned on. After the calcium hydroxide and water are fully mixed into a thin paste, slowly add acetylacetone, continue to stir, and fully shear and stir After 2 hours of reaction. Close the reaction vessel, open the steam valve and the vacuum valve, and keep stirring and drying for 2.5 hours at a temperature of 50-80°C under a negative pressure of 0-0.1 MPa. The water vapor is discharged from the gas outlet pipe 7, and after the drying is finished, the steam valve and the vacuum valve are closed. Coarse powder was obtained after reaction and drying, which was pulverized by a pulverizer to obtain 2351.50 g of calcium acetylacetonate (calculated as dry product), which should be 2372.86 g according t...

Abstract

The invention discloses a technology for producing calcium acetylacetonate with a solid phase method. technology is characterized in that acetylacetone, a calcium compound and water are added to a high-shear reaction device in the ratio being 42%-44%: 12%-17%: 41%-44% to be subjected to a shear stirring reaction for 1.5-2 h, vacuum drying is performed under the negative pressure of 0-0.1 MPa and at the temperature of 50-80 DEG C, and calcium acetylacetonate is obtained. With the adoption of the technology, the operation steps are simplified, the yield is increased, the energy consumption and the cost are reduced, the wastewater treatment expense is reduced, and the environmental pollution problem caused by wastewater is solved. No waste is emitted in the whole technological process, production technology integration is realized, and automatic production can be realized after combination. The technology conforms to the policy orientation of the national green and environment-friendly advanced industry.

Description

technical field [0001] The invention relates to a process and a device for producing calcium acetylacetonate, in particular to a process and a device for producing calcium acetylacetonate by a solid phase method. Background technique [0002] With polyvinyl chloride (PVC) as the main raw material, various plastic products can be produced, including hard products such as plates, pipes, pipe fittings, and special-shaped materials, and soft products such as films, pipes, shoes, toys, cable materials, and artificial leather. , industry and agriculture, etc. are widely used. However, since PVC materials are prone to thermal degradation during processing and use, resulting in darker colors and lower performance, stabilizers must be added to prevent or alleviate thermal degradation during processing and use. There are many kinds of heat stabilizers, mainly including lead salts, metal soaps, organotin compounds, organic stabilizers and composite stabilizers. With the promulgation ...
