Acetone, also known as dimethyl ketone.It is a colorless, flammable liquid with a minty odor at room temperature and pressure. Its chemical formula is CH₃COCH₃, its molecular weight is 58.08, and its CAS number is 67-64-1. It is easily soluble in water and organic solvents such as methanol, ethanol, ether, chloroform, and pyridine. It is flammable, volatile, and has a relatively active chemical property.
Acetone
Acetone is an important organic compound with a wide range of uses in industry, medicine, daily life and other fields:
- Industrial solvent: Acetone has good solubility and can quickly dissolve a variety of resins, pigments and other ingredients, so that coatings and paints have good fluidity and coating properties. It is widely used in the manufacture and construction process of coatings and paints; in the plastics industry, it can be used as a solvent for the dissolution, plasticization and molding of plastics. It can also be used in the dissolution and plasticization process of rubber to help rubber and various additives mix evenly and improve the processing performance and physical properties of rubber.
- Chemical synthesis raw materials: Acetone reacts with hydrocyanic acid to generate acetone cyanohydrin, and then a series of reactions can be used to obtain methyl methacrylate, which is an important raw material for the production of organic glass. It can react with phenol under the action of an acidic catalyst to produce bisphenol A. It can also be used to prepare acetic anhydride through oxidation, condensation and other reactions. Acetic anhydride is an important acetylation reagent and is widely used in the pharmaceutical, fragrance, dye and other industries.
- Medical field: It is also a commonly used organic solvent that can be used to extract active ingredients from plants or other biological materials. It has a certain bactericidal effect and can be used for the disinfection of medical devices, laboratory equipment, etc. However, due to its flammability, safety precautions must be taken in practical applications.
- Daily life: Dimethyl ketone can remove stains such as oil, glue, and nail polish, and is often used to clean surfaces such as furniture, floors, and glass. It is also the main ingredient in common nail polish removers.
