ASTM E299 Standard Test Method for Trace Amounts of Peroxides in Organic Solvents

    ASTM E299 Introduction

    The scope of this test method includes the analysis of dilute peroxide solutions in various organic solvents, commonly used as catalysts or reaction initiators in tests. Additionally, it covers the detection of peroxides produced through autoxidation in certain plants, which can include ethers, acetals, dienes, and alkyl aromatic compounds.

    ASTM E299 Test Method

    Solution Preparation and DeaerationIn the procedures outlined in ASTM E299, samples are dissolved in a mixture of acetic acid and chloroform. The solution is deaerated before adding the potassium iodide reagent solution.
    Reaction in the DarkThe mixture reacts for an hour, releasing iodine in the dark. The solution’s absorbance is measured to find the active oxygen content. A de-aerated cell is used, and measurements are taken at 410 nm for accuracy.

    E299 Equipment and Sample Preparation

    Specimen DetailThis test method covers organic solvents containing active oxygen in the range of 5 to 80 µg/g (ppm) or higher.
    Specimen SizeSpecimen size is not stated for ASTM E299

    E299 Test Result and Interpretation

    In this test method, calculations are performed to determine both the quantity of active oxygen contained within the sample and the corresponding density values.

    ASTM E299 is related to tests, including ASTM D1193 for reagent water specification and ASTM E180 for testing procedures for industry-grade chemicals.

    Use of E299 in Various Industries

    It is a critical method used in industries such as chemical manufacturing, pharmaceuticals, and petrochemicals to ensure safety and quality in organic solvents by detecting trace levels of peroxides, which may degrade chemical stability or cause an explosion.

    Materials Commonly Tested with E299

    This test checks upon materials such as ether based solvents, hydrocarbons, alcohols, and volatile organic compounds for safety and performance as they tend to form peroxide and are commonly used in industry.

    Common Challenges and Troubleshooting in E299 Testing

    Testing is hindered by sample contamination, poor handling and interference from solvents. Troubleshooting will ensure fresh stored reagents, extremely clean glassware, as well as adherence to the recommended sample handling protocols in reducing variability and ensuring proper peroxide detection.

    Safety and Best Practices in E299 Testing

    The volatile samples require safety in testing. Best practices include well-ventilated areas, PPE, and strict reagent handling. Accurate titration and avoiding peroxide buildup in solvent storage mitigate risks.

    Importance of E299

    This specification is important for safety and product reliability in industries using organic solvents. It detects trace peroxides and quantifies them to avoid explosive situations and damage to equipment.
