Problems solved by technology

[0005] Most of the existing tribromostyrene purification processes use activated carbon diatomite as an adsorbent, or use crystallization methods. The former has poor adsorption effect and cannot meet the requirements for producing high-purity tribromostyrene. The latter has complicated operation steps and consumes Large amount of energy, long time

Abstract

The invention relates to a preparation method of a polymeric material for tribromobenzoic acid. Hydroxyapatite, 1,1,1,3,3,3-hexafluoroisopropyl acrylate, 1,1'-phenylsulfonyl-4,4'-diallyl ether, methyl3-(trimethylsilyl)-4-pentenoate, dimethyl (3-oxo-1,3-dihydroisobenzofuran-1-yl)phosphonate, cyclopentadienylrhenium tricarbonyl, ammonium persulfate, sodium dodecyl benzene sulfonate and water are added to a reaction kettle in parts by weight, stirred uniformly and heated for a reaction, a product obtained after the reaction ends is filtered, washed and dried, and the polymeric material for tribromobenzoic acid is obtained.

Description

technical field [0001] The invention relates to a purification aid for tribromobenzoic acid, in particular to a method for preparing a polymeric material for tribromobenzoic acid. Background technique [0002] As a reactive flame retardant with high bromine content, tribromostyrene is easy to add to reactive air groups such as amino groups. It is used as a flame retardant additive in the field of coatings, and it can be copolymerized with unsaturated olefins such as propylene to form a certain bromine content. It is a polymer material with intrinsic flame retardant properties, and the copolymerized product has the advantages of no precipitation, good compatibility with the substrate, and high flame retardant efficiency. [0003] CN104447192A discloses a method for purifying tribromostyrene, the steps are as follows: dissolve crude tribromostyrene in an organic solvent, add activated carbon or diatomaceous earth for adsorption treatment, and then separate solid and liquid to ...
