Abstract:

The Gas phase chromatography measurement method for phenols product composition is established. Phenols products are analyzed with 4 kinds of capillary chromatographic columns and the measuring conditions are optimized. The degree of separation for all components can reach 1.3, the accuracy and degree of precision are superior to GB/T 2601—1981, GB/T 2604—1981 and JIS standards and close to ASTM standard. The method is applicable to analyze the compositions of all coking phenols products.
