| introduction | sec-butyl acetate, also known as sec-butyl acetate, is a colorless flammable liquid with fruit fragrance. sec-butyl acetate has many uses, which can be used as perfume, medicine, solvent, metal cleaning agent, reaction medium and extractant. In recent years, due to the increasingly stringent requirements for environmental protection worldwide, people tend to reduce the amount of solvents such as toluene, xylene, and ketones. Its development direction is to develop and use resin coatings and acetate. Oxygen-containing solvents replace aromatic hydrocarbons and ketones in volatile coating formulations, and sec-butyl acetate meets this trend. |
| properties | sec-butyl acetate has the advantages of strong solubility, moderate volatilization speed, high extraction yield, low toxicity and less residue. The properties and indexes of sec-butyl acetate are basically similar to that of n-butyl acetate, but the production cost is low, and it is an ideal substitute for n-butyl acetate. |
| application | has good solubility to many substances and can be used industrially as a solvent for manufacturing nitrocellulose paint, acrylic paint, polyurethane paint, etc. These paints can be used as aircraft wing paint, artificial leather paint, automobile paint, etc. It can also be used in the manufacturing process of celluloid products, rubber, safety glass, coated paper, patent leather and other products. It can also be used as a volatile solvent in printing inks for offset printing and other applications; in addition, it can also be used as a quick-drying agent for photosensitive materials. sec-butyl acetate can be used as the refining of penicillin; due to its moderate volatility and good skin permeability, it can also be used as a drug absorption promoting component. |
| use | solvent for nitric acid fiber and paint. Gasoline antiknock agent. |
