Foreword
This standard is GB/T 2601-1981 "composition of the phenolic gas chromatography method", GB/T 2604-1981 "o-cresol group
Into the GC determination method "based on the revised and integrated into a standard.
This standard replaces GB/T 2601-1981, GB/T 2604-1981.
This standard compared with GB/T 2601-1981, GB/T 2604-1981 main changes are as follows.
--- Added foreword, normative references, etc .;
--- Increasing the principle and the sample to take the requirements;
--- Capillary column instead of packed column, and the determination of the method was revised;
--- The precision of the test was revised.
This standard is proposed by China Iron and Steel Association.
This standard by the metallurgical industry standard Institute of Information centralized.
This standard is mainly drafted by. Anshan Iron and Steel Co., Ltd., Shanghai Baosteel Chemical Co., Ltd. Meishan Branch, Metallurgical Industry Information Standard

This standard replaces the standards previously issued as follows.
--- GB/T 2601-1981;
--- GB/T 2604-1981.
Determination of the composition of phenolics by gas chromatography
1 Scope
This standard specifies the principles of the determination of the composition of phenolic compounds, reagents and materials, equipment, samples taken, test procedures, the results of calculations, reports and
Precision.
This standard applies to coking products in the determination of the composition of phenols.
Method one is suitable for the determination of coking phenol, industrial phenol and o-cresol in coking products;
Method two for coking products in the industrial cresol, m-cresol, industrial xylenol and other components of the determination.
