sec-Butyl Acetate CAS#105-46-4
Environmentally Friendly: Sec-butyl acetate serves as an eco-friendly alternative to volatile organic solvents like toluene and xylene, making it a safer choice for industries aiming to reduce environmental impact.
Pleasant Odor: Its fruity, pleasant smell makes it a popular choice in fragrances and as a solvent in consumer products.
Versatile Applications: It is widely used in various industries, including pharmaceuticals, metal cleaning, extraction, and resin coatings, due to its effectiveness as a solvent and cleaning agent.
Low Toxicity: Compared to other aromatic hydrocarbons and ketones, sec-butyl acetate offers lower toxicity, making it a safer choice for industrial applications.
Sec-butyl acetate, also referred to as sec-butyl ethanoate, is a colorless, flammable liquid with a pleasant fruity odor. It serves a variety of purposes, including use in fragrances, pharmaceuticals, solvents, metal cleaning agents, reaction media, and extraction agents. In recent years, growing global environmental concerns and stricter chemical regulations have driven efforts to reduce the use of volatile organic solvents such as toluene, xylene, and ketones.
As a result, the industry is shifting toward environmentally friendly alternatives like oxygenated solvents. Sec-butyl acetate, as an acetate ester, aligns well with this trend and is increasingly favored for use in resin coatings and formulations where it can effectively replace more hazardous aromatic hydrocarbons and ketone-based solvents.
