The manufacturing method
of brominated epoxy
1. Introduction

brominated epoxy is an important chemical production raw material, widely used in plastics, rubber, coatings and other fields. With the continuous development of science and technology, the manufacturing method of brominated epoxy is also constantly improved and optimized. This article will introduce a common manufacturing method of brominated epoxy.

2. Materials and Equipment

1. Materials: epichlorohydrin, bromine, sodium hydroxide, methanol, etc.
2. Equipment: reaction kettle, stirrer, thermometer, dropping device, reflux condenser, etc.

3. manufacturing steps

1. add epichlorohydrin and methanol into the reaction kettle according to a certain proportion, and stir evenly.
2. While stirring, the aqueous solution of bromine and sodium hydroxide is slowly added dropwise to control the reaction temperature within a certain range.
3. During the reaction, the unreacted bromine and methanol were recovered by reflux condenser to reduce waste and pollution.
4. After completion of the reaction, the reaction solution was allowed to stand and separate into layers, and the lower crude brominated epoxy was separated.
5. The crude brominated epoxy was refined to obtain a high purity brominated epoxy product.
Precautions for
4.

1. During the manufacturing process, the reaction temperature and dripping rate should be strictly controlled to prevent side reactions and product quality problems.
2. Regular inspection and maintenance of equipment and pipelines to ensure normal operation of equipment and stable product quality.
3. Operators should be professionally trained and familiar with the manufacturing process and safe operation procedures to ensure the safe and smooth production process.

5. Conclusion The manufacturing method of

brominated epoxy involves many links and precautions, and the reaction conditions and operation process need to be strictly controlled to ensure product quality and production safety. By continuously optimizing the manufacturing method and improving the technical level, the production efficiency and product quality of brominated epoxy can be further improved, and make greater contributions to the development of the chemical industry.
