Scope

This document specifies a test method for the determination of propylene oxide and trace impurities in propylene oxide for industrial use by gas chromatography.
This document is suitable for the determination of propylene oxide which is produced by ethylbenzene co-oxidation (PO/SM), isobutane co-oxidation (PO/TBA), cumene co-oxidation (CHPPO), hydrogen peroxide oxidation (HPPO) and chlorohydrin. This document is applicable for determination of propylene oxide with a purity ≥ 99,70 % and impurity content ≥ 0,000 3 %.
