Description of ASTM-D4423 2010ASTM D4423 - 10Standard Test Method for Determination of Carbonyls In C 4 HydrocarbonsActive Standard ASTM D4423 | Developed by Subcommittee: D02.D0.04 Book of Standards Volume: 05.02
Translated Standard: Russian ASTM D4423Significance and Use The determination of the carbonyl content of polymerization-grade 1,3-butadiene is necessary, since in some polymerization reactions, the presence of carbonyls in excess over some specified amount can have a deleterious effect upon the polymer properties or the reaction itself, or both. 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 1.2, as found in polymerization-grade 1,3-butadiene. 1.4 WARNING Mercury has been designated by many regulatory agencies as a hazardous material that can cause central nervous system, kidney and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury containing products. See the applicable product Material Safety Data Sheet (MSDS) for details and EPA s website http://www.epa.gov/mercury/faq.htm for additional information. Users should be aware that selling mercury and/or mercury containing products into your state or country may be prohibited by law. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 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.
