Rubber compounding ingredients - Organic vulcanizing agents - Determination of organic peroxide content
This document 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 gas-chromatography method.
a)      titration method A for group a: Peroxyketals:
1,1-Di(tert-butylperoxy)cyclohexane (DTBPC; CAS Registry Number®[1]:3006-86-8)
1,1-Di(tert-butylperoxy)-2-methylcyclohexane (DBPMC; CAS RNÂ 147217 40 1);
1,1-Di(tert-butylperoxy)-3,3,5-trimethylcylcohexane (DBPTC; CAS RNÂ 6731 36 8);
2,2-Di(tert-butylperoxy)butane (DBPB; CAS RNÂ 2167 23 9);
Butyl 4,4-di(tert-butylperoxy)valerate (BPV; CAS RNÂ 995 33 5);
b)      titration method B for group b: Diacyl peroxides:
Dibenzoyl peroxide (CAS RNÂ 94 36 0);
Di(2,4-dichlorobenzoyl) peroxide (CAS RNÂ 133 14 2);
Di(4-methylbenzoyl) peroxide (CAS RNÂ 895 85 2);
c)       titration method C for group c: Diaralkyl and alkyl-aralkyl peroxides:
Di(tert-butylperoxyisopropyl)benzene (CAS RNÂ 2212 81 9);
Dicumyl peroxide (CAS RNÂ 80 43 3);
tert-Butyl cumyl peroxide (CAS RNÂ 3457 61 2);
d)Â Â Â Â Â Â gas-chromatography for dialkyl peroxides, using a capillary or packed column.
2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane (CAS RNÂ 78 63 7)
