Butyl Acrylate Acrylonitrile (BAN) is an important raw material for the production of chemicals, which is widely used in the fields of synthetic rubber, plastics and fibers. In this paper, we will introduce a method to manufacture Butyl Acrylate Acrylonitrile, which is made from butyl acrylate and acrylonitrile as raw materials by copolymerization reaction.
I. Preparation of raw materials
1. Butyl acrylate: Butyl acrylate is a colorless and transparent liquid with pleasant odor. It is easily soluble in organic solvents such as water, ethanol and ether.
2. Acrylonitrile: Acrylonitrile is a colorless and transparent liquid with a pungent odor. It is insoluble in water but soluble in organic solvents.
2. Equipment preparation
1. Polymerization kettle: the equipment used to carry out the copolymerization reaction should have the functions of stirring, heating and cooling.
2. Conveying pump: used for conveying raw materials and products.
3. Storage tank: used for storing raw materials and products.
3. Manufacturing steps
1. Feeding: add butyl acrylate and acrylonitrile into the polymerization kettle according to certain proportion.
2. Initiate reaction: add initiator to start the polymerization reaction.
3. Controlling the reaction temperature: control the temperature of the polymerization reaction within a suitable range by heating and cooling system.
4. Stirring: Through the stirring system, make the raw materials fully mixed and the reaction homogeneous.
5. Post-treatment: After the reaction is finished, carry out post-treatment, including cooling, separation, purification and other steps, to get the product of butyl propyl acrylate nitrile.
4. Precautions
1. Strictly control the proportion of raw materials and feeding order to ensure the smooth progress of the reaction.
2. Control the reaction temperature and time to prevent quality problems of the product.
3. In the post-treatment process, attention should be paid to the purity and yield of the products to improve the production efficiency.
V. Safety and environmental protection
1. During the manufacturing process, safety operation regulations should be strictly observed to prevent fire, explosion and other accidents.
2. The waste gas, waste water and other pollutants generated in the manufacturing process shall be effectively treated to meet the requirements of environmental protection.
VI. Quality control
1. Conduct quality inspection of raw materials to ensure that the quality of raw materials meets the standard requirements.
2. Carry out real-time monitoring of the production process, find and solve problems in time to ensure stable product quality.
3. Conduct quality inspection on products to ensure that the products meet the relevant standards and customer requirements.
In short, the manufacture of butyl acrylate nitrile requires strict control of raw materials, equipment, manufacturing steps, precautions, safety and environmental protection, and quality control to ensure product quality and production efficiency. Meanwhile, the safety management and environmental protection in the manufacturing process need to be strengthened to guarantee the smooth progress of the manufacturing process.
