Scope

1.1 This test method2,3 covers organic solvents containing active oxygen in the range from 5 to 80 μg/g (ppm) or higher. By using a special reaction-absorption cell, the test method can be extended to cover the range from 0 to 5 ppm. The test method can be used to determine numerous peroxide classes of varying reactivity such as hydroperoxides, diacyl peroxides, diaroyl peroxides, peresters, and ketone peroxides. The stable di-tert-alkyl peroxides do not react under the conditions of analysis.

1.2 Solvents that can be analyzed successfully include saturated and aromatic hydrocarbons, alcohols, ethers, ketones, and esters. In addition, the test method is applicable to olefinic solvents and to certain compounds that contain α, β, and conjugated unsaturation. Solid samples that are soluble in the acetic acid-chloroform solvent also can be analyzed.

1.3 Review the current Safety Data Sheets (SDS) for detailed information concerning toxicity, first aid practices, and safety precautions.

1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

1.5 This standard does not purport to address 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.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Significance and Use

4.1 Dilute solutions of peroxides in various organic solvents frequently are used as catalysts or reaction initiators. Peroxides also can be formed through autoxidation in certain classes of compounds including ethers, acetals, dienes, and alkylaromatic hydrocarbons and present a potential safety hazard. This test method provides a procedure for determining the peroxide or active oxygen level.
