Scope

ISO 14932:2012 specifies four methods for the determination of the content of the following groups of organic peroxides used as rubber vulcanizing agents. There are three titration methods and one using capillary gas-chromatography as given below.
Titration method A for group a) peroxyketals: DTBPC: 1,1-Di(tert-butylperoxy)cyclohexane; DBPMC: 1,1-Di(tert-butylperoxy)-2-methylcyclohexane; DBPTC: 1,1-Di(tert-butylperoxy)-3,3,5-trimethylcylcohexane; DBPB: 2,2-Di(tert-butylperoxy)butane; BPV: Butyl-4,4-di(tert-butylperoxy)valerate.
Titration method B for group b) diacylperoxides: Dibenzoyl peroxide; Di(2,4-dichlorobenzoyl) peroxide; Di(4-methylbenzoyl) peroxide.
Titration method C for group c) diaralkyl and alkyl-aralkyl peroxides: Di(tert-butylperoxyisopropyl)benzene; Dicumyl peroxide; tert-Butyl cumyl peroxide.
Capillary gas-chromatography for dialkyl peroxides: 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane.
