Conversion of ASTM Distillation to TBP
Distillation for Gasoline, LCO, and Decanted Oil

Gasoline TBP
(From Appendix 9, TBP 50% point = 213°F)
Given D-86 From Appendix 10

50% - 30% = 53°F 30% TBP = 140°F
30% - 10% = 35°F 10% TBP = 77°F
10% - IBP = 25°F IBP TBP = 26°F
70% - 50% = 72°F 70% TBP = 297°F
90% - 70% = 84°F 90% TBP = 383°F
EP - 90% = 64°F EP TBP = 501°F
LCO TBP
(From Appendix 9: TBP 50% point = 561°F)

Given D-86 From Appendix 10
50% - 30% = 33°F 30%TBP = 511°F
30% - 10% = 4FF 10% TBP = 441°F
10% - IBP = 73°F IBP TBP = 343°F
70%-50% = 29°F 70%TBP = 601°F
90% - 70% = 51°F 90% TBP = 660°F
EP-90% = 39°F EPTBP = 712°F
Decanted Oil TBP
(From Appendix 9: TBP 50% point = 744°F)

Given D-86 From Appendix 10
50% - 30% = 33°F 30% TBP = 694°F
30% - 10% = 41°F 10% TBP = 624°F
10% - IBP = 236°F IBP TBP = 425°F
70% - 50% = 51°F 70% TBP = 807°F
90% - 70% = 75°F 90% TBP = 886°F
