Standard Test Method for Percent of Non-Amines in Fatty Nitrogen Compounds (Withdrawn 2007)

SCOPE
1.1 This method covers the determination of the percentage of non-amine components in fatty amines and diamines.
1.2 This standard does not purport to address all of the safety problems, 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.>
WITHDRAWN RATIONALE
This test method covers the determination of the percentage of non-amine components in fatty amines and diamines.
Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this test method was withdrawn in March 2007 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Standard Test Method for
Percent of Non-Amines in Fatty Nitrogen Compounds
This standard is issued under the fixed designation D 2082; 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 (e) indicates an editorial change since the last revision or reapproval.
This method was prepared jointly by the American Society for Testing and Materials and the American Oil Chemists’ Society.
1. Scope
1.1 This method covers the determination of the percentage
of non-amine components in fatty amines and diamines.
1.2 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 appro-
priate safety and health practices and determine the applica-
bility of regulatory limitations prior to use.

3. Summary of Test Method
3.1 Aspecimen of the fatty amine compound is dissolved in
alcohol and passed through an ion exchange column. The
amine components of the specimen are retained on the column
andthenonaminecomponentspassthroughthecolumnandare
collected and weighed.Acorrection factor is applied to correct
for any amine components that pass through the column.
4. Apparatus
4.1 Chromatographic Columns, made by attaching 500-mL
bulbs with 24/40 joints to chromatographic tubes and with
attached fritted-glass disks inside a 19/22 joint (Fig. 1).
