Historical Standard: ASTM D4423-00(2006) Standard Test Method for Determination of Carbonyls In C 4 Hydrocarbons
SUPERSEDED (see Active link, below)
ASTM D4423
1. Scope
1.1 This test method covers the determination of carbonyls (ketones and aldehydes) in C 4 hydrocarbons. This test method was tested on polymerization-grade 1,3-butadiene.
1.2 The applicable range for this test method is 0 to 50 mg/kg carbonyls calculated as acetaldehyde.
1.3 Other C 4 hydrocarbons and their mixtures besides polymerization-grade 1,3-butadiene could be tested using this same test method. However, the precision section of this test method covers only carbonyls in applicable range as listed in , as found in polymerization-grade 1,3-butadiene.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
