Scope

This standard specifies the spectrophotometric method for the determination of trace carbonyl compounds in carbon tetraolefins. This standard is applicable to the determination of trace carbonyl compound content in 1-butene and 1,3-butadiene. The minimum detection concentration is 0.5 mg/kg (based on butanone). This standard does not apply to the determination of isobutylene.
