ASTM D3160-12
(Test Method)Standard Test Method for Phenol Content of Cumene (Isopropylbenzene) or AMS (alpha-Methylstyrene)
Standard Test Method for Phenol Content of Cumene (Isopropylbenzene) or AMS (alpha-Methylstyrene)
SIGNIFICANCE AND USE
This test method is useful in determining phenol in the range from 5 to 50 mg/kg in commercially available cumene or AMS.
Phenol will inhibit certain reactions involving cumene or AMS.
SCOPE
1.1 This test method covers the determination of phenol in refined cumene (isopropylbenzene) or AMS (α–methylstyrene).
1.2 This test method has been found applicable in the range from 5 to 50 mg/kg of phenol in refined cumene (isopropylbenzene) or AMS (α–methylstyrene).
1.3 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 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. For specific hazard statements, see Section 7.
