Embodiment 1

[0028] Example 1: Reaction raw materials: 1500 g of acetylacetone (99.8% content), 630 g of zinc oxide (99.8% content), 1800 g of deionized water.

[0029] First, add zinc oxide and deionized water into the reaction vessel (4) from the feeding port (6), turn on the stirring paddle (9), wait until the zinc oxide and water are fully mixed into a thin paste, slowly add acetylacetone, and continue stirring, After fully shearing and stirring for 2 hours. Close the reaction vessel, open the steam valve and the vacuum valve, and continue stirring and drying for 2 hours at a temperature of 30-60° C. under a negative pressure of 0-0.1 MPa. Water vapor is discharged from the gas outlet pipe (7), and after the drying is completed, 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 1931.15g of zinc acetylacetonate (calculated as dry product), which should be 1968.56g according to theoretica...

Embodiment 2

[0033] Example 2: Reaction raw materials: acetylacetone 2000g (content 99.7%), zinc oxide 780g (content 99.7%), deionized water 2000g.

[0034]First, add zinc hydroxide and deionized water into the reaction vessel (4) from the feeding port (6), turn on the stirring paddle (9), wait until the zinc oxide and water are fully mixed into a thin paste, slowly add acetylacetone, and continue stirring , after fully shearing and stirring for 2 hours. 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 30-60° C. under a negative pressure of 0-0.1 MPa. Water vapor is discharged from the gas outlet pipe (7), and after the drying is completed, 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 2574.90g of finished zinc acetylacetonate (calculated as dry product), which should be 2622.11g according to theoretical...

Abstract

The invention discloses a technology for producing zinc acetylacetonate with a solid phase method. The technology is characterized in that acetylacetone, a zinc compound and water are added to a self-made high-shear reaction device in the ratio being 38%-42%: 16%-24%: 38%-42% 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 30-60 DEG C, and zinc acetylacetonate is obtained.

Description

technical field [0001] The invention relates to a process and a device for producing zinc acetylacetonate, in particular to a process and a device for producing zinc 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 of man...
