ActiveAromatic hydrocarbons--Test method of acid wash
芳烃酸洗试验法
Application Summary AI generated
This standard specifies a test method for determining the color change of aromatic hydrocarbons after treatment with sulfuric acid, which indicates the presence of unsaturated or easily sulfonatable impurities. It is applied in the chemical industry for quality control of aromatic hydrocarbon products such as benzene, toluene, and xylenes, particularly during production and before use in downstream processes like solvent extraction or petrochemical synthesis. The test is used to assess product purity and suitability for applications requiring low reactivity with acids.
