GB/T 3711-2008
ActiveMethod of determination for neutral oils and pyridine bases contents of phenol products
酚类产品中性油及吡啶碱含量测定方法
Application Summary AI generated
This standard specifies the laboratory test method for determining the content of neutral oils and pyridine bases in phenol products. It is applied in the chemical industry, specifically for quality control and acceptance testing of coal-tar-derived phenols, cresols, and xylenols used in manufacturing resins, disinfectants, and antioxidants. The method ensures product purity by quantifying non-phenolic impurities that affect downstream processing and end-use performance.
