    Significance and Use

    This test method provides a means for determining the percent of dicumyl peroxide in technical and refined grades of this material. This test method is specific for dicumyl peroxide. No interference is encountered from dimethylbenzyl alcohol, acetophenone, or other minor impurities normally associated with commercial dicumyl peroxide.

    1. Scope

    1.1 This test method covers the assay of dicumyl peroxide in commercially available refined grades of dicumyl peroxide. Technical grades can also be assayed, provided that impurities that interfere chromatographically are absent (see Note 1). These materials nominally contain approximately 99 and 92 % of dicumyl peroxide, respectively.

    Note 1—In the assay of technical grade dicumyl peroxide, errors are possible if the product contains an impurity that elutes with the same retention time as the internal standard. A chromatogram obtained under the test conditions minus the internal standard will determine whether an interference situation exists in the assay of a particular technical grade product. If an impurity is noted, and its retention time is slightly different from that of the internal standard, the interference can often be eliminated by the use of a column known to have a high plate count.

    1.2 Review the current material safety data sheets (MSDS) for detailed information concerning toxicity, first aid procedures, and safety precautions.

    1.3 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.

    1.4 This 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. Specific precautionary statements are given in Section 7.
