It is used as an acetylating agent, and is used in the manufacture of pharmaceuticals (aspirin), dyes, and acetate fibers. It is prepared by oxidizing oxygen with acetaldehyde in the presence of cobalt acetate or copper acetate catalyst at 55-65 °C.

Mainly used in organic synthesis, synthetic fiber, dyes, pharmaceuticals, pesticides and other industries.

Uses: Communication cable insulation.

Uses: Communication cable insulation.

Mainly used as a solvent, and used in the synthesis of dyes and some pharmaceutical intermediates.

It is mainly used in the manufacture of resins, plasticizers, synthetic fibers, cosmetics and explosives, and as a solvent to formulate antifreeze for engines.

It is mainly used as a solvent, such as a solvent such as nitrocellulose, rubber, resin, grease, paint, and household medicine. It can also be used as a plasticizer for resins, a tobacco anti-drying agent, a fiber lubricant, and a desiccant for natural gas.

Used as organic synthesis intermediates, binders, emulsifiers, coatings. Oleic acids and their esters are widely used in industry.

Important organic synthetic raw materials and synthetic resin monomers are ethylene monomers with very fast polymerization rates.

Acrylonitrile is an important monomer for synthetic fibers, synthetic rubbers and synthetic resins. Polyacrylonitrile fiber, that is, acrylic fiber, is obtained from acrylonitrile, and its properties are very similar to wool, so it is also called synthetic wool.
