Third, The Product Process
There Are Three Industrial Methods: Phosphorus  Oxychloride And Chloroethanol Reaction; Phosphorus Trichloride And Chloroethanol  Reaction Reoxidation; Phosphorus Oxychloride And Ethylene Oxide Reaction  (Industrial Commonly Used Method).
1, Phosphorus Oxychloride And Ethylene  Oxide To Sodium Metavanadate As A Catalyst, At 50 ° C Reaction, The Reaction By  Neutralization, Washing, Vacuum Dehydration Off The Low Boiling, That Is, The  Finished Product. Chlorohydrin Can Also Be Used As Raw Materials, And Phosphorus  Oxychloride or Phosphorus Trichloride Reaction To Produce Tris (2-Chloro Ethyl)  Phosphate,Flame Retardant TCEP.
2, 326 Kg Of Phosphorus Oxychloride And 1.0 Kg Of Sodium  Metavanadate Into The Reactor. The Nitrogen In The Autoclave Was Driven By  Nitrogen, And 650 Kg Of Ethylene Oxide Was Introduced Under Vacuum And Stirred  At 45 To 50 ° C For 2 To 3 Hours. Evaporation Of Excess Ethylene Oxide After  Alkali Neutralization To Neutral, Washed, Vacuum Dehydrated. Finished  Product.
3. Put Phosphorus Oxychloride And Sodium Metaphosphate Into The  Reactor. Nitrogen To Drive The Air, In The Vacuum Under The Access To Ethylene  Oxide, At 45 ~ 50 ℃ Stirring 2 ~ 3h. Evaporation Of Excess Ethylene Oxide After  Alkali Neutralization To Neutral, Washed, Vacuum Dehydrated Finished.

Fourth, Use:
1. Tris (2-Chloroethyl) Phosphate,Flame Retardant TCEP Has Excellent Flame  Retardancy, Excellent Resistance To Low Temperature And UV Resistance, The Steam  Can Only Be Used At 225 ℃ Above The Direct Ignition Can Be Fired, But The Fire  The Source Is Immediately Self-Extinguishing. This Product Is A Flame Retardant  Not Only Can Improve The Material Level Of Flame Retardant Materials, But Also  Improve The Flame Resistance Of Water Resistance, Acid Resistance, Cold  Resistance And Antistatic Properties. Commonly Used In Flame Retardant  Nitrocellulose And Acetate Fiber As The Substrate Of Paint Coatings, Unsaturated  Polyester, Polyurethane, Acrylic, Phenolic Resin, Can Also Be Used For Soft PVC  Plastic Flame Retardant. This Product Is Used For The Amount Of Unsaturated  Polyester 10% To 20%, In The Polyurethane Rigid Foam (Flame Retardant Polyether  As Raw Material) Can Be About 10% In The Soft PVC Used As Auxiliary Plastic  Flame Retardant When The 5% To 10%. Flame Retardants, Uranium, Thorium,  Plutonium, Technetium And Other Rare Metal Separation Solvent or  Extractant.
2. This Product Is Widely Used In Chemical Fiber Fabrics,  Cellulose Acetate As A Flame Retardant, In Addition To Self-Extinguishing, But  Also Improve Water Resistance, Cold Resistance And Antistatic Properties. The  General Amount Of 5 To 10 Copies. This Product Is An Excellent Flame Retardant  For Synthetic Materials, And Has A Good Role In The Promotion, Widely Used In  Cellulose Acetate, Nitrocellulose Varnish, Ethyl Cellulose, Polyvinyl Chloride,  Polyvinyl Acetate, Polyurethane, Phenolic Resin , In Addition To  Self-Extinguishing Products, But Also Improve The Physical Properties Of  Products, Products Feel Soft, Also Known As Oil Additives And Rare Elements Of  The Extractant, And Flame Retardant Rubber Conveyor Belt Is The Main Flame  Retardant Materials , The General Amount Of Added 5% To 10%.
3. Used As  Additive Type Halogenated Phosphate Flame Retardant And Plasticizer. Molecules  In Both Phosphorus And Chlorine, Flame Retardant Effect Is Remarkable, Not  Volatile And Hydrolysis, Good Stability To Ultraviolet Light. Applicable To  Phenolic Resin, Polyvinyl Chloride, Polyvinyl Acetate, Polyurethane And So On.  Also Used As Nitrocellulose Coating Flame Retardant, PVC Flame Retardant Plasticizer, Metal Extractant, Gasoline Additives And Polyimide Processing Aids  And So On.
