| titleOfInvention | Synthesis method of high-purity bromotrimethylphenyl hydrindene |
| abstract | A method for synthesizing high-purity bromotrimethylphenyl hydrindene comprises the following steps: s1, dissolving 1,3, 3-trimethyl-1-phenylindane in an organic solvent, adding the solution into a bromine chloride solution containing a catalyst, and carrying out heat preservation reaction to obtain a bromo-trimethyl phenyl hydrindene crude product; s2, adding an alkaline substance to neutralize excessive bromine after heat preservation, and removing impurities under the action of peroxide and an alkali metal compound to obtain a product; and S3, adding a heat stabilizer, and distilling under the action of water and an emulsifier to obtain a pure bromotrimethylphenyl hydrindene product. The invention uses 1,3, 3-trimethyl-1-phenyl indan and bromine chloride to carry out bromination reaction, thereby improving the utilization rate of bromine, adopts composite catalyst and reaction control agent, has the highest reaction yield of more than 95 percent, and has the advantages of low cost, high product quality, mild reaction conditions, easy control, high product purity and good thermal stability. |
