The raw materials of acetylaniline production mainly include aniline and acetone. Among them, aniline is an aromatic amine, is one of the most important organic chemical raw materials, widely used in dyes, drugs, synthetic resins, rubber and other fields. Acetone, as an acetylation agent, is an important intermediate in fermentation industry and a basic chemical in the field of organic synthesis. Acetanilide is usually produced by acetylation, which is the reaction of aniline and acetone to form acetanilide. The reaction is generally carried out in the presence of alkaline catalysts such as sodium hydroxide or hydroxylamine, and the reaction temperature is generally 80-100℃. In the reaction, acetone acts as acetylation, replacing a hydrogen atom in an aniline molecule with an acetyl group to form acetanilide. After the reaction is completed, high purity acetanilide products can be obtained by acid neutralization, filtration and other technological steps.1. Dye pigments: as an intermediate used in the synthesis of dye pigments, such as printing and dyeing dyes, fabric dyeing agents, food, medicine and other fields. 2. Drugs: Used as raw materials in the synthesis of certain drugs and medical compounds, such as diuretics, analgesics and anesthetics. 3. Spices: Can be used as synthetic spices, such as aromatic compounds. 4 synthetic resin: can be used to synthesize a variety of resins, such as phenolic resin, urea formaldehyde resin, etc. 5. Coating: can be used as a dye dispersant for coating, improve the coloring power of paint and adhesion of paint film. 6. Rubber: can be used as raw material of organic synthetic rubber, can also be used as rubber plasticizer and buffer.1. To stimulate the upper respiratory tract. 2.
