Third, The Production Process

Phosphorus Oxychloride Direct Method (Thermal Method) And Phosphorus Trichloride Indirect Method (Cold Method).

(1) The Thermal Process Of Phenol Dissolved In Pyridine And Anhydrous Benzene Solvent, Not More Than 10 ℃ Below, Slowly Adding Phosphorus Oxychloride, And Then In The Reflux Humidity For 3-4h, Cooled To Room Temperature, The Reactants By The Pyridine Was Washed With Water For Dehydration Of Sodium Sulfate And Sodium Sulfate, And The Benzene Was Distilled Off Under Normal Pressure. The Fraction Was Collected At 243-245 ℃ / 1.47KPa By Vacuum Distillation. The Product Was Cooled And Crystallized.

(2) The Phenol Was Dissolved In Pyridine And Anhydrous Benzene Solvent By Cold Method, Then Phosphorus Trichloride Was Added Dropwise At 40 ° C To Produce Triphenyl Phosphite, And Chlorine Was Passed At 70 ° C To Produce Triphenyl Phosphate Acid And Then Hydrolyzed At 80 ° C To Produce Triphenyl Phosphate. The Hydrolyzate Is Washed With Water, Neutralized With Alkali, And Then Concentrated Under Reduced Pressure To Obtain A Finished Product. Refining Method: Often Contain Phenol, Phosphoric Acid And Acid Phosphate And Other Impurities. Recrystallization From Ethanol or A Mixture Of Ethanol And Solvent Gasoline.
