Packing: Net Weight 200KG / Galvanized Iron Drum (A Small Cabinet Playing With 16 Tons), 1000KG / IB Bucket (A Small Cabinet 18 Tons) Or 23 Tons ISOTANK.


Second, Product Use
Triisobutyl Phosphate (TIBP) Is Used In Cement Defoamers And Penetrants. Widely Used In Printing And Dyeing, Ink, Construction, Oil Additives And So On. Triisobutyl Phosphate (TIBP) Is Also Called Tri-Tert-Butyl Phosphate.


Third, The Production Process
The First Step: Esterification Reaction: Reaction Ratio Of Phosphorus Oxychloride: Isobutanol = 1: 5 ~ 1: 9; First Added To The Total Amount Of Isobutanol 5 To 15% Of Isobutanol Mixed And Then With The Remaining Isobutanol Together Into The Reactor, Or The Catalyst Added To The Phosphorus Oxychloride, Stirring In The Cooling Conditions, Dropping Phosphorus Oxychloride, To Maintain The Reaction Temperature Between 15 ~ 60 ℃, The Time Of Dropping Phosphorus Oxychloride Is 1 To 6 Hours, The Addition Is Completed, Stirring Is Continued For 0.5 To 4 Hours, And The Temperature Is Maintained At Not Lower Than 5C. The Following Are The Same As The "
The Second Step: Dewaxing Acid: In The Pressure Under The Conditions Of The Reaction After The End Of The Material Heating And Evaporation, Not To Participate In The Reaction Of Isobutanol And The Reaction Of The By-Product Of Hydrogen Chloride, The Highest End Of The Terminal Temperature Can Not Exceed The Isobutanol Boiling Point Of 10 ° C; Dewaxing Vacuum Maintained At -0.06Mpa Above, Dewaxing Time Of 1 To 8 Hours.
Step 3: Neutralization Washing: Alkaline Is Added To The Post-Alcoholated Material With Stirring To Remove Hydrogen Chloride Remaining In The Material At A PH Of 6 To 8 And Then To 30 To 100 ℃ Hot Water Washing, Adding The Amount Of Water For The Material Quality Or Volume Of 0.5 To 1.5 Times, After Standing To The Water Layer, The Initial Product Of Triisobutyl Phosphate.
Step 4: Distillation: First Detect The Initial PH Of Triisobutyl Phosphate Is Between 6.5 ~ 7.5, If Not Meet The Requirements, Then Use Alkaline Substances To Adjust The PH Value To 6.5 ~ 7. 5, And Then Distilled Under Reduced Pressure Conditions, Remove The Low Boiling Components, The Collection Of Triisobutyl Phosphate Products.
