Introduction

National Standard of the People's Republic of China GB/T 1653—2023 o- and p-Nitrochlorobenzene

Background of Standard Formulation and Analysis of Technological Evolution

GB/T 1653—2023 o- and p-Nitrochlorobenzene is the fourth revision of the national standard based on the original standard, mainly considering the technological progress of the industry and changes in market demand. This standard replaces the previous GB/T 1653—2013 version.

The main changes in the new standard include: deleting the control item of crystallization point of dry products, optimizing the product quality index system, and updating the sampling and testing methods. These changes reflect the industry's higher requirements for quality control and safety technology.

Interpretation of main contents

1. Main revisions of the standard

The control item of crystallization point of dry products and its test method have been deleted, simplifying the quality inspection process.
Optimized product quality indicators: improved purity requirements, adjusted the content limits of low-boiling substances, high-boiling substances and organic impurities.
Updated sampling and testing methods: adjusted the solvent use and moisture determination methods, and added regulations on the allowable difference of parallel determinations.

2. Analysis of key technical requirements

Project category	Comparison of quality indicators (%)
Project category	Superior products	First-class products	Qualified products
Purity requirement	≥99.80	≥99.50	≥99.00
Low boiling matter content	≤0.05	≤0.10	≤0.20
High boiling point content	≤0.10	≤0.15	≤0.25

3. Safety technology and environmental protection requirements

According to GB 12268-2012, o- and p-nitrochlorobenzene belong to Class 6.1 toxic substances and must strictly comply with the dangerous goods transportation regulations. Effective protective measures should be taken during production and storage to ensure personnel safety.

Implementation suggestions

Strictly control the quality of raw materials: Suppliers are required to provide quality inspection reports to ensure that the raw materials meet national standards.
Optimize production process: Use new catalysts and reaction conditions to reduce by-product generation.
Strengthen laboratory construction: Equip with advanced gas chromatographs and other equipment to improve detection accuracy.
Strengthen employee training: Focus on training new standard requirements and safe operation specifications.
Establish a traceability system: Make product quality traceable throughout the process to ensure rapid problem location and processing.
