Tris(1,3-Dichloro-2-Propyl)Phosphate (TDCPP)

Tris(1,3-Dichloro-2-Propyl)Phosphate(TDCPP) Production Process

1. Main Raw MaterialPhosphorus Oxychloride (Industrial), Epichlorohydrin (Industrial).

2. Synthesis Of PrincipleEpichlorohydrin And Phosphorus Oxychloride As The Main Raw Material, Select The Appropriate Solvent, Synthetic TDCP In The Catalyst, The Chemical Reaction Equation Is As Follows:

3. Experimental ProcedurePhosphorus Oxychloride, Catalyst And Solvent Were Added Sequentially Fitted With A Stirrer, A Thermometer, A Condenser And A Dropping Funnel, Four-Neck Flask, Heated To A Suitable Temperature, Epichlorohydrin Was Slowly Added Dropwise Under Stirring, The Addition Was Complete Insulation The Reaction Period Of Time And Then Distilled Under Reduced Pressure To Recover The Solvent, The Residue Was Washed With Water, Aqueous Sodium Carbonate, Was Distilled To Obtain A Colorless Transparent Viscous Liquid TDCP.

The Reaction Of Epichlorohydrin With Phosphorus Oxychloride In The Catalyst Is A Violent Exothermic Reaction, So The Material Should Be Heated To A Suitable Temperature, Start Dropping Epichlorohydrin · If The Reaction Temperature Is Too Low, The Reaction Speed Is Very Slow With The Added Gradually Epichlorohydrin, When Accumulated To A Certain Extent The Concentration Will Cause A Violent Reaction, Directly Affect The Quality And Yield Of The Reaction Product; If The Reaction Temperature Is Too High, The Reaction Intense, Causing Red Material, Part Epichlorohydrin From Poly And Local Materials Charring, Leading Products Darken The Color Yellow, The Viscosity Increases And Turbid Reaction Temperature Should Be Controlled At 50 ^ -88 ℃, Preferably 50 -.} - 70 ℃, When The Product Is Not Color Or Light Yellow Transparent Viscous Liquid, And The Yield Is Greater Than 90%.

Phosphorus Oxychloride And Epichlorohydrin Generation Unit Vinegar Under Normal Conditions Faster, More Difficult To Generate A Diester And Triester Of Particular Triester, Even At A High Temperature Is Generated More Slowly, Required Catalyst Accelerate The Reaction. The Amount Of Catalyst Have A Greater Impact On The Reaction. Little Amount, The Catalytic Effect Is Not Obvious, Slow Reaction, The Reaction Time Is Extended.

Epichlorohydrin And The Reaction Dropping Time Longer Holding Time, The Product Acid Number Is, The Higher The Conversion Rate Reaction, But The Reaction Time Is Too Long, The Energy Consumption Increases. Not The Economy. Of Particular Note Is That The Ring Epichlorohydrin Dropping Time Can Not Be Too Short, Otherwise In The Limited Time To Accumulate More Epichlorohydrin Will Cause A Violent Reaction, A Sharp Rise In Temperature, Epichlorohydrin From Polyethylene, The Material Viscosity, Color Yellow , The Product Acid Number Increase And Yields Decline. Tests Showed That Epichlorohydrin Addition Time About 2h, 2.0} 3.5h Incubation Time As Well.
