Standard Test Methods for Pentaerythritol (Withdrawn 2011)

Significance and Use

These test methods provide a measurement of sulfate, ash, moisture (water), hydroxyl content, assay by dibenzal and gas chromatography, and phthalate ester color of pentaerythritol. The results of these measurements can be used for specification acceptance.

Scope

1.1 These test methods cover the testing of pentaerythritol for use in the manufacture of alkyd resins and other synthetic resins.

1.2 The test procedures appear in the following sections:

Section
Sulfate ash5 to 10
Moisture11 to 16
Hydroxyl17 to 22
Assay (by dibenzal)23 to 29
Assay (by gas chromatography)30 to 41
Phthalate ester color42 to 49

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 For purposes of determining conformance of an observed or a calculated value using this test method to relevant specifications, test result(s) shall be rounded off "to the nearest unit" in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E 29.

1.5This 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.
