Butyl Acetate: 116.16 g/mol
Description:
Ethyl Acetate and Butyl Acetate are clear, colorless, volatile organic liquids with characteristic fruity odors. Both are esters of acetic acid and serve as excellent solvents for numerous natural and synthetic resins, cellulose derivatives, oils, and coatings.
They are widely used in the paint, coatings, adhesives, leather, ink, and pharmaceutical industries for their fast to moderate evaporation rates and low toxicity.
Ethyl Acetate is known for its quick-drying and low-boiling properties, while Butyl Acetate offers a slower evaporation rate, improving flow and leveling in coating applications.
Paints & Coatings:
Used as active solvents in paints, lacquers, enamels, and varnishes for smooth film formation.
Adhesives & Inks:
Employed in adhesive formulations and printing inks for their balanced solvency and drying properties.
Pharmaceuticals:
Used as extraction solvents and intermediates in drug formulation and purification.
Leather & Textile Industry:
Solvents in artificial leather coatings, cleaning, and finishing processes.
Laboratory Use:
Common solvent for chromatography and chemical synthesis.
