Second, Product Use
Use One: Used To Increase The Plastic Molding Process When The Plasticity And Flow Properties.
Use Two: For Nitrocellulose, Acetate And Polyvinyl Chloride Plastic Plasticizer.
Use Three: For Gas Chromatography Fixed Liquid, Cellulose And Plastic Plasticizer And Celluloid In The Camphor Non-Flammable Substitutes.
Use Four: Gas Chromatography Fixed Solution (The Maximum Temperature Of 175 ℃, Solvent Ether), Selectivity And Polyethylene Glycol Similar To The Selective Retention Of Alcohol Compounds.


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 Sulphate And Filtered To Remove Sodium Sulfate. The Benzene Was Distilled Off Under Normal Pressure. The Fraction Of 243-245 ℃ / 1.47KPa Was Collected By Vacuum Distillation. The Product Was Cooled And Crystallized.
(2) The Cold Method Of Phenol Dissolved In Pyridine And Anhydrous Benzene Solvent, And Then At 40 ° C Drop Of Phosphorus Trichloride To Generate Triphenyl Phosphite, Continue At 70 ° C Into The Chlorine Gas To Produce Triphenyl Phosphate Acid And Then Hydrolyzed At 80 ° C To Produce Triphenyl Phosphate. The Hydrolyzate Is Washed With Water, Neutralized With A Base, 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.
