PHT4-DIOL
Product description:
Molecular formula: C2H6O5S2
Molecular weight: 174. 19604
CAS:370071-69-5
Chinese name: Tetrabromophthalic anhydride diol
English name: Methanesulfonic anhydride
Character description: Light amber viscous liquid, soluble in alcohol, toluene, acetone, etc., insoluble in water.
Production process: Stir tetrabromophthalic anhydride and diethylene glycol evenly and then add the catalyst. Under the protection of protective gas, the temperature is raised to the reaction temperature for the first time and the reaction is carried out. After the reaction is completed, an organic solvent is added to dissolve the above reaction materials. , add propylene oxide after cooling down, raise the temperature for the second time to perform a heat preservation reaction, perform hot filtration after the reaction, and then distill the organic solvent to remove the product.
