Rubber compounding ingredients. Organic vulcanizing agents. Determination of organic peroxide content. | Status: Superseded, Withdrawn

1 Scope This International Standard 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.

1.1 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.
