Butyl acetate is an important organic chemical raw material, which is widely used in paint, printing ink, leather, medicine, perfume and other fields. This article will detail the properties and uses of butyl acetate.

1. the nature of butyl acetate

1. physical properties of
butyl acetate is a colorless transparent liquid, 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 0.726mPa · s. Insoluble in water, miscible with alcohol, ether and other organic solvents. Can dissolve grease, natural resin, vinyl resin, cellulose acetate, polystyrene, acrylic resin, chlorinated rubber, rubber, etc.

2. Chemical properties
the chemical properties of butyl acetate is relatively stable, but it is prone to decomposition and reaction under high temperature, light and acid conditions. Butyl acetate can be reacted with alcohols, acids, bases, etc. by esterification, hydrolysis, etc.

2. the use of butyl acetate

1.
of the paint industry butyl acetate is an important solvent in the paint industry, can be used for the preparation of lacquer, varnish, enamel and so on. Butyl acetate has good solubility and leveling ability, which can improve the construction performance and drying speed of the coating.

2. Printing ink
Butyl acetate is used as a solvent in printing ink, which can adjust the viscosity and drying performance of the ink and improve the printing quality and efficiency.

3. Butyl acetate
in leather industry can be used in leather processing, which can improve the softness and gloss of leather, and increase the water resistance and abrasion resistance of leather.

4.
of Pharmaceutical Industry Butyl acetate is used as solvent and extractant in the pharmaceutical industry, and can be used to prepare drugs and extract natural products.

5. Fragrance industrial
butyl acetate has a fruity flavor and can be used to prepare flavors and spices, widely used in food, cosmetics and other fields.

In conclusion, butyl acetate, as an important organic chemical raw material, has a wide range of uses in the field of chemical production raw materials.
