Third, The Production Process
The Production Of Trimethyl Phosphate TMP Is The Reaction Of Phosphorus Oxychloride With Methanol In The Presence Of Potassium Carbonate To Produce Trimethyl Phosphate. At The Same Time The Reaction To Produce Potassium Phosphate Potassium Salt, With Dimethyl Sulfate Reaction To Produce Trimethyl Phosphate. The Crude Product Of Trimethyl Phosphate Is Washed With Water, Decolorized, Dehydrated And Distilled Under Reduced Pressure. Consumption Of Raw Materials Fixed: Phosphorus Oxychloride 1094kg / T, Methanol 686kg / T.
Adding Methanol And Potassium Carbonate To The Reaction Kettle, Cooling To 5 ° C, Starting Dropping Phosphorus Oxychloride, The Temperature Is Controlled Below 30 ℃, 2h After The Drop, And Then Stirring 0.5h, PH Control In 7 ~ 8; Then Add Dimethyl Sulfate, Reflux 3h After The Recovery Of Methanol, And Then The Pot Material Cooled To 20 ℃ Below, Adding Carbon Tetrachloride Filter, Filter Cake With A Small Amount Of Carbon Tetrachloride Washing, Washing Liquid And Filtrate Combined To Recover Carbon Tetrachloride , Vacuum Distillation Was Crude. The Crude Product Plus Distilled Water And Activated Carbon, Filtered And Anhydrous Potassium Carbonate After Dehydration, The Final Vacuum Distillation Products.
