Trixylyl Phosphate (TXP)

Trixylyl Phosphate(TXP) Production Process

First, The Raw Materials And Production Part 1. The Raw Materials Are Mixed Xylenol (AR), Phosphorus Trichloride (AR) And Chlorine (CP). 2 .. Device 1000mL Four-Neck Flask; 250mL Pressure-Equalizing Dropping Funnel; 500mL Separatory Funnel; Pump; Electric Heating Mantle, Distillation Columns.

 
Second, The Process
 
1. Esterification Take 1000mL Four-Necked Flask, Adding A Certain Amount Mixed Xylenol, Adding Quantitative PCl3 At A Constant Pressure Funnel, And A Water Bath Heated Xylenol. Open Stirring, Evacuated, And At A Constant Speed Dropwise PCl3, Controlling The Reaction Temperature, The Addition Was Complete, Stirring Was Continued For 30min, The Reaction Was Complete. According To Orthogonal Experiment, Integrated A Variety Of Factors,
We Set The Ratio Of Raw Materials As: Xylenol: Phosphorus Trichloride (Mol Ratio) = 1:1.1, Dropping To 2 Drops / S, The Reaction Temperature Is 50 ~ 80 ℃.
 
2. Chloride Esterification Reaction, Continue To The Reaction Flask And Chlorine Gas, Chlorine Gas Flow Meter Adjustment, Speed Control Chlorine, The Reaction Was Normal, The Reaction Temperature Is Controlled At Below 70 ℃, Until The Reaction Was Complete.
 
3. Hydrolysis Adding An Appropriate Amount Of Water In A Dropping Funnel, Strict Control Of Dropping (Due To Hydrolysis Reaction Violent) And Open The Vacuum Pump To Exhaust Gas To Produce Complete Hydrolysis.
 
The Hydrolysis Products After Distillation Neutralized, Washed With Water To PH = 7, The Isolated Crude, Crude Vacuum Distillation (1.33kPa) To Obtain The Final Product.
 

Third, The Results

The Process Reaction Temperature Is Low, Intermediate Reaction Easy To Control, Higher Product Yields (In Two Cresol Yield Of Up To 92%), Raw Materials, Low Cost, Stable Product Quality, Various Technical Indicators Have Reached Or More Than Similar Products. Products By Users In Tarpaulin And Rubber Conveyor Trial Better.

Packing: NW 200KG / galvanized iron (a small cabinet loaded 16 tons a child care), 1000KG/IB barrels (a small cabinet loaded 18 tons), or 23 tons ISOTANK.
