| 1. Scope | ||
|
1.1 This test method covers the determination of total p-tertiary-butylcatechol inhibitor added to polymerization and recycle grades of butadiene or to other C 4 hydrocarbon mixtures containing no phenolic material other than catechol or no oxidized phenolic material other than that derived from oxidation of catechol. In general, all phenols and their quinone oxidation products are included in the calculated catechol content. Small amounts of polymer do not interfere. This test method is applicable over the range of TBC from 50 to 500 mg/kg. 1.2 The values stated in SI units are to be regarded as standard. The values stated in inch-pound units are for information only. 1.3This 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. |
