Use | for the production of phenylphosphonic acid and dimethyl phenylphosphonate. The product is subjected to dehydrochlorination condensation with hydroquinone to form a flame-retardant phosphorus-containing polymer and used as a heat stabilizer for polyesters. The product is reacted with octanol in the presence of pyridine to form octyl phenylphosphonate, which can be used as a low volatility plasticizer. as an intermediate in pesticides and pharmaceuticals |
production method | is obtained from the oxidation of phenylthio phosphorus dichloride. |
