The manufacturing method
of allyl chloride
allyl chloride is an important organic compound, which is widely used as a raw material for chemical production. It has active chemical properties and can be used to make many important derivatives. This article will detail the manufacturing method of allyl chloride.

1. properties and uses of chloropropene

chloropropene is a colorless transparent liquid with a pungent odor. It is insoluble in water and soluble in organic solvents. Chloropropene chemical properties of active, prone to addition, substitution, polymerization and other reactions. Therefore, it is an important organic synthesis intermediate, widely used in the manufacture of pesticides, pharmaceuticals, dyes, spices and other chemicals.

2. allyl chloride manufacturing method

1. propylene chlorination
propylene chlorination method is the main method of manufacturing allyl chloride. The method uses propylene as raw material to produce chloropropene through chlorination reaction. The specific manufacturing process is as follows:
(1) Mixing propylene and chlorine gas, controlling a certain temperature and pressure, and performing a chlorination reaction. The reaction produces allyl chloride and hydrogen chloride.
(2) The chloropropene and hydrogen chloride are separated by distillation. Chloropropene is collected as the main product, and hydrogen chloride can be recycled as a by-product.
2. Acrylic acetate method
Acrylic acetate method is a method for manufacturing chloropropene with acrylic acetate as raw material. The specific manufacturing process is as follows:
Acrylic acetate (1) reacts with chlorine gas under the action of a catalyst to generate allyl chloride and acetic acid.
(2) The chloropropene and acetic acid are separated by distillation. Chloropropene is collected as the main product, and acetic acid can be recycled as a by-product.

3. Precautions for the manufacture of chloropropene

1. Control the reaction temperature and pressure to avoid the occurrence of side reactions and improve the purity of the product.
2. Select the appropriate catalyst to improve the reaction rate and selectivity.
3. Strengthen the maintenance and maintenance of equipment to ensure the normal operation of equipment and stable product quality.
4. Strengthen the safety management of the production process to prevent leakage and fire accidents.

4. the market prospect of allyl chloride

allyl chloride as an important organic compound, has a wide range of applications in the field of chemical production raw materials. With the continuous development of science and technology, the manufacturing process and technology of chloropropene will be further improved and optimized to improve product quality and output. At the same time, with the continuous expansion of domestic and foreign markets, the application fields of chloropropene will be further expanded, and the market demand will continue to maintain steady growth. Therefore, the market prospect of allyl chloride is very broad.

In conclusion, as an important raw material for chemical production, allyl chloride has broad application prospects and market demand. By mastering its manufacturing methods and precautions, high-purity chloropropene can be produced and contribute to the development of the chemical industry.
