3.Product Technology

(1) Catalytic Synthesis Of Supported Heteropolyacid Salt

(1) Preparation Of Immobilized Heteropolyacid Salt Catalyst A Certain Amount Of TiC L4 Is Taken, Adjusted To PH 7-8 By Adding 12% Ammonia Water, Precipitated, Filtered And Washed Until Cl Ion Is Checked With 0.1 Mol/LAg NO 3 . Drying. The Above Raw Materials Are Reacted With A Certain Amount Of Pre-Heat Treated H4S IW12O40·ηH2O For 1.5 H. The Whole Process Solution Is Kept Near Boiling State, And The Water Is Slowly Distilled Off And Dried To Obtain A Catalyst Composed Of TiSiW12O40/Tio2.

(2) Synthesis The Quantitative Addition Of Cresol Was Added To The Reactor, And The Prepared TiSiW12O40/Tio2 Catalyst (1.0% Of The Total Amount Of Raw Materials) Was Stirred, Heated To 60 ° C, And Phosphorus Oxychloride Was Added Dropwise, And The Addition Was Completed Within About 1 H. The Temperature Was Raised To 100 ° C To Continue The Reaction, The Humidity Was Controlled At 100-120 ° C Until Substantially No HCI Evolution, The Reaction Was About 8 H. The Catalyst Was Filtered Off, And Then The Product Was Obtained By Distillation Under Reduced Pressure To Obtain A Product With A Yield Of About 85.5%.

(2) Indirect Method Of Phosphorus Trichloride (Cold Method) Mixing Cresol And Phosphorus Trichloride At 15-20 ° C To Form Tricresyl Phosphite, Then Introducing Chlorine Gas At 60-70 ° C To Form Dichloro Trimethyl Phosphite Is Further Hydrolyzed At 50 ° C To Form Tricresyl Phosphate. Finally, It Is Washed, Neutralized, Evaporated And Dehydrated And Distilled Under Reduced Pressure, And The Fraction Taken At 340-360 ° CkPa Is Taken As A Finished Product.

Purification Method: Separation Of Isomers Is Difficult, And Impurities Other Than Isomers Are Generally Removed By Distillation Under Reduced Pressure.
