Published By:ASTM International (ASTM)
This test method covers the determination of carbonyls (ketones and aldehydes) in C4 hydrocarbons. This test method was tested on polymerization-grade 1,3-butadiene.
The applicable range for this test method is 0 mg ⁄kg to 50 mg ⁄kg carbonyls calculated as acetaldehyde.
Other C4 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.
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.
