Standard Test Method for Determination of Carbonyls In C4 Hydrocarbons
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 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.
1.2 The applicable range for this test method is 0 to 50 mg/kg carbonyls calculated as acetaldehyde.
1.3 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.
1.4 WARNING
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.
Significance 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.
