Butyl acetate is an important organic chemical raw material, widely used in coatings, printing inks, leather, medicine, spices and other fields. This article will detail the properties and uses of butyl acetate.
1. The properties of butyl acetate
1. Physical properties
butyl acetate is a colorless transparent liquid with a pleasant fruit flavor. Relative density 0.8826(20/4 ℃), melting point -73.5 ℃, boiling point 126.1 ℃, refractive index 1.3993, flash point (open cup) 21.7 ℃, viscosity 0.716mPa · s. Insoluble in water, miscible in ethanol, ether and other organic solvents.
2. Chemical properties
butyl acetate has the general properties of esters, and is prone to hydrolysis under acidic or alkaline conditions to generate acetic acid and butanol. In addition, butyl acetate can also occur alcoholysis, aminolysis, ester exchange and other reactions.
2. the use of butyl acetate
1.
of the paint industry butyl acetate is one of the important solvents in the paint industry, can be used to prepare a variety of coatings, such as alkyd resin paint, acrylic paint, polyurethane paint and so on. As a coating solvent, butyl acetate has good solubility and volatility, which can adjust the leveling and drying of the coating, and improve the density and gloss of the coating film.
2. printing ink
butyl acetate is often used as a binder in printing ink, which can improve the fluidity and transfer of ink, and make the printed matter colorful and dry quickly.
3. Butyl acetate
in leather industry can be used for degreasing and solvent extraction in leather processing, which can improve the softness and gloss of leather.
4.
in the pharmaceutical industry, butyl acetate can be used as an extraction solvent in the pharmaceutical industry to extract active ingredients from natural plants, such as flavonoids, alkaloids, etc.
5. Fragrance Industrial
Butyl acetate has a pleasant fruit flavor and can be used to prepare a variety of flavors, such as peach, apricot, strawberry and other fruit flavors.
In conclusion, butyl acetate, as an important organic chemical raw material, has a wide range of applications in the field of chemical production raw materials.
