The manufacturing method
of oil chemical industry
1. Introduction

Oil chemical industry refers to the process of producing various chemical products and intermediates through chemical reactions and processing technologies using oil as raw materials. Oil chemical industry plays an important role in the field of chemical production raw materials, and its products are widely used in plastics, rubber, coatings, medicine, food and other fields. This article will introduce the manufacturing method of oil chemical industry, including the source of oil, pretreatment, chemical reaction and post-treatment process.

2. the source of oil and grease and pretreatment

1 source of oil and grease: mainly from animal and vegetable oil, microbial oil and synthetic oil. Among them, animal and vegetable oil is the main source, including soybean oil, palm oil, rapeseed oil and so on.
2. Pretreatment: Before the chemical reaction, the oil needs to be pretreated, including degumming, deacidification, dehydration, decolorization and deodorization, to ensure the quality of the oil and the smooth progress of the reaction.

3. oil chemical reaction

1. Transesterification reaction: Transesterification reaction is one of the common reactions in oil chemical industry. The fatty acid composition of oil can be changed by transesterification reaction to produce oil chemical products with specific properties.
2. Hydrogenation reaction: Hydrogenation reaction is the process of converting unsaturated fatty acids in oils and fats into saturated fatty acids. The stability, oxidation resistance and thermal stability of oils and fats can be improved by hydrogenation reaction.
3. oxidation reaction: oxidation reaction is the process of converting hydrocarbon groups in oils and fats into oxygen-containing functional groups such as hydroxyl and carboxyl groups. Through oxidation reaction, chemical products such as alcohol, acid and ester can be produced.
4. Sulfonation reaction: Sulfonation reaction is the process of converting hydrocarbon groups in fats and oils into sulfonic acid groups. Chemical products such as sulfonates and sulfonated oils can be produced through the sulfonation reaction.

4. post-treatment process

1. separation and purification: after chemical reaction oil chemical products need to be separated and purified, in order to obtain higher purity products. Common separation methods include distillation, extraction, crystallization, etc.
2. Blending and mixing: According to needs, different types of oleochemical products can be blended and mixed to obtain products with specific properties.
Precautions in the manufacturing process of
5.

1. Control reaction conditions: In the oil chemical manufacturing process, it is necessary to strictly control the reaction conditions, including temperature, pressure, time, etc., to ensure the smooth progress of the reaction and the quality of the product.
2. Prevent pollution: In the production process, it is necessary to keep the equipment and containers clean and avoid the introduction of impurities and pollutants to ensure the purity and quality of the product.
3. Safe operation: The oleochemical manufacturing process involves some hazardous chemicals and high temperature and high pressure operations. It is necessary to strictly abide by the safety operation procedures to ensure production safety.

6. conclusion

oil chemical industry plays an important role in the field of chemical production raw materials, through different chemical reactions and processing technology can produce various properties of oil chemical products. In the manufacturing process, it is necessary to strictly control the reaction conditions, prevent pollution and safe operation and other precautions to ensure product quality and production safety. With the continuous development of science and technology, the manufacturing methods and technologies of oleochemical industry will continue to be updated and improved to provide more high-quality chemical products and intermediates for various fields.
