Scope: This document specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation and storage of industrial trans-1-chloro-3,3,3-trifluoropropene. It is applicable to the product made from 1,1,1,3,3-pentachloropropane.

Introduction

Interpretation of the National Standard for Industrial Trans-1-Chloro-3,3,3-Trifluoropropene [HCFO-1233zd(E)]

Trans-1-Chloro-3,3,3-trifluoropropene (hereinafter referred to as "HCFO-1233zd(E)") is an important industrial fluoroolefin, widely used in refrigerants, foaming agents and synthetic intermediates. This article will be based on the GB/T 43094-2023 standard to deeply interpret its technical requirements, test methods and practical applications.

1. Background and significance of standard formulation

With the increasing global attention to environmental protection, fluoroolefins have been widely used in many industrial fields due to their excellent physical and chemical properties. However, due to their special chemical structure and potential safety risks, their quality and technical requirements are particularly important.

2. Comparison of standard frameworks

Dimensions	Type I products (refrigerants)	Type II products (foaming agents/intermediates)
Content of trans-1-chloro-3,3,3-trifluoropropene (%)	≥99.8	≥99.8
Water content (%)	≤0.002	≤0.01
Acidity (in HCI) (%)	≤0.000 1	≤0.000 1
Evaporation residue (%)	≤0.01	≤0.01
Chloride test	Pass	Pass

3. Interpretation of key technical requirements

According to Table 1, the technical requirements of trans-1-chloro-3,3,3-trifluoropropene cover multiple dimensions such as purity, moisture, acidity, evaporation residue and chloride. Among them:

Content of trans-1-chloro-3,3,3-trifluoropropene: ≥99.8%, ensuring the high purity requirements of the product.
Water and acidity: Strictly controlled at extremely low levels to avoid negative impact on downstream applications.

4. Test methods and practical applications

GB/T 43094-2023 standard specifies test methods such as gas chromatography, electrolysis and gravimetric analysis for the determination of various indicators of HCFO-1233zd(E). These methods not only ensure the accuracy of the data, but also provide reliable technical support for actual production.

5. Implementation suggestions

To ensure the effective implementation of the standard:

Manufacturers should establish a complete quality management system and strictly carry out production and inspection in accordance with the requirements of the standard.
During product packaging and transportation, special attention should be paid to moisture protection, sun protection and high temperature avoidance to prevent performance degrade.
It is recommended to calibrate production equipment and testing instruments regularly to ensure data accuracy.
