Значение и использование

The permanganate time can be used to judge the presence of oxidizable materials that may be associated with manufacture or contamination during distribution and to assess compliance with a specification.

Many chemical processes that use acetone or methanol, or both, involve catalyst, metals, or ligand complexes that are sensitive to oxidation. Since oxidizable contaminants may affect the efficiency of these processes, this test method provides a comparative test for manufacturing control and assessing compliance with a specification.

Область применения

1.1 This test method covers the detection in acetone and methanol of the presence of impurities that reduce potassium permanganate.

1.2 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.

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

1.4 For specific hazard information and guidance, consult the supplier's Material Safety Data Sheet.

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.
