Test conditions: True boiling point distillation

Equipment

The distillation up to 240° C. is performed according to D-2892.

Conditions*

Cut points are as follows:

• Atmospheric distillation: C5-180° C. AET.

• 100 Torr: 180-240° C. AET.

The atmospheric cut points are corrected to 760 mmHg.

Volume:

Volume expansion or contraction is normalized among fractions boiling at less than 150° C. in proportion to their yields. (Usually the "loss" is negative due to volume expansion.)

Loss:

Loss up to 240° C. AET is distributed with two-thirds in the gas-fraction and one-third in the first liquid fraction.


*AET = average equivalent temperature; Torr. ≈ 1 mmHg ≈ 0.0193 lbf/sq in.
