ASTM D2007-19

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D2007 − 11 (Reapproved 2016) D2007 − 19
Standard Test Method for
Characteristic Groups in Rubber Extender and Processing
Oils and Other Petroleum-Derived Oils by the Clay-Gel

Absorption Chromatographic Method
This standard is issued under the fixed designation D2007; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope Scope*
1.1 This test method covers a procedure for classifying oil samples of initial boiling point of at least 260 °C (500 °F) into the
hydrocarbon types of polar compounds, aromatics and saturates, and recovery of representative fractions of these types. This
classification is used for specification purposes in rubber extender and processing oils.
NOTE 1—See Test Method D2226.
1.2 This test method is not directly applicable to oils of greater than 0.1 % by mass pentane insolubles. Such oils can be
analyzed after removal of these materials, but precision is degraded (see Appendix X1).
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 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 safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use. Specific warning statements are given in 6.1, Section 7, A1.4.1, and A1.5.5.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 The following terms refer to the hydrocarbon types and structural groups as measured by this test method:
3.1.2 aromatics—aromatics, n—material that, on percolation, passes through a column of adsorbent clay in a n-pentane eluent
but adsorbs on silica gel under the conditions specified.
3.1.3 asphaltenes, or n-pentane insolubles—insolubles, n—insoluble matter that precipitates from a solution of oil in n-pentane
under the specified conditions.
3.1.4 polar aromatics—aromatics, n—synonym for polar compounds.
3.1.5 polar compounds—compounds, n—material retained on adsorbent clay after percolation of the sample in n-pentane eluent
under the conditions specified.
3.1.6 saturates—saturates, n—material that, on percolation in a n-pentane eluent, is not adsorbed on either the clay or silica gel
under the conditions specified.

gel plus clay in the lower section. n-pentane is then charged to the double column until a definite quantity of effluent has been
collected. The upper (clay) section is removed from the lower section and washed further with n-pentane. A toluene-acetone
