    Significance and Use

    4.1 The presence of pentane and lighter hydrocarbons in gasolines, naphthas, and similar petroleum distillates interferes in Test Method D2789. Pentane and lighter hydrocarbons are separated by this test method so that the depentanized residue can be analyzed and so the pentane and lighter hydrocarbons can be analyzed by other methods, if desired.

    4.2 Under the conditions specified in the test method some C5 and lighter hydrocarbons remain in the bottoms, and some C6 and heavier hydrocarbons carry over to the overhead. Expressed as volume percent of charge, the amounts are typically 2 % or less, which is considered adequate for the purpose designated under Scope. It should be recognized, however, that when expressed as volume percent of overhead or of bottoms the percentages can be higher, making this test method unsuitable for any purposes not designated under Scope.

    1. Scope

    1.1 This test method covers the removal of pentanes and lighter hydrocarbons from gasolines, naphthas, and similar petroleum distillates to prepare samples suitable for the determination of hydrocarbon types in accordance with Test Method D2789. In addition, this test method determines the volume percent of bottoms remaining after depentanization.

    1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
