Introduction

Interpretation of GB/T 25786-2016, the National Standard of the People's Republic of China

Background and Significance of the Standard

GB/T 25786-2016 "2-Amino-4-acetylaminoanisole" replaces the original GB/T 25786-2010, and mainly revise and optimize the quality requirements, test methods and marking labels of products. This standard is applicable to the production and quality control of dyes and their intermediates and other related fields.

Main changes to the product

Addition of liquid product specifications:The requirements for the appearance and mass fraction of liquid products are clarified.
Adjustment of quality control items:The mass fraction test of water content is cancelled, and sampler requirements and liquid product sampling regulations are added.
Optimized detection method: High performance liquid chromatography (HPLC) was used for purity determination to ensure the accuracy of the results.

Comparison table of standard frameworks

Project dimensions	Requirements of the 2010 edition	Updates to the 2016 edition
Appearance assessment method	Visual method, temperature conditions not specified	Newly added cooling to 5-10℃ condition
Mass fraction determination	Applicable only to powdered products	Also applicable to liquid products, with stricter indicators
Requirements for testing equipment	General laboratory equipment	Clear HPLC instrument model and performance parameters

Implementation suggestions and precautions

Sampling stage: Ensure that the sample is representative and strictly follow the standards such as GB/T6678-2003.

Practical application case analysis

During the production process of a certain enterprise, it was found that the product quality score did not meet the standard. By optimizing the production process and strictly controlling the reaction conditions, the product purity was successfully improved and reached the standard of superior products. This shows that following standard operating procedures is crucial to improving product quality.

Explanation of professional terms

HPLC (High Performance Liquid Chromatography):

A commonly used separation and analysis technology used to determine the purity and impurity content of a substance.

Diazonium salt:

A compound generated by amine compounds and sodium nitrite under acidic conditions, commonly used in the synthesis and detection of dye intermediates.
