More recently Daubert published a new method for distillation curves interconversion using the following equations:
2 T50 = A4(T50)#*
T30 = T50 – AT3
T10 = T30 – AT2
To = T10 – AT, ,
T70= T50 + AT s
T90 = T70 + AT,
T90 = T95 + AT,
Where T and T the ASTM and TBP temperature respectively, both in • F
The subscripts o and f refer for initial and final temperature respectively
Ai and Bi curve constant given in below table
