Applications of N-butyl Acetate

N-butil acetate, referred to as butil acetate, is a colorless, transparent liquid with a pleasant fruity odor. The lower homologues are hardly soluble in water; miscible with organic solvents such as alcohols, ethers and ketones. Flammable. Less acute toxicity. N-butil acetate is an excellent organic solvent. It has good solubility for ethyl cellulose, cellulose acetate butyrate, polystyrene, methacrylic resin, chlorinated rubber and many natural gums. It is obtained by direct esterification of acetic acid and n-butanol under the catalysis of sulfuric acid, followed by neutralization, dehydration and fractionation.


Prepare n-butil acetate from acetic acid and n-butanol.

Industrial n-butil acetate production processes include continuous and batch methods, depending on the scale of production.

In recent years, the use of acid catalysts such as solid acids and heteropoly acids that are less corrosive to equipment has been used to catalyze the preparation of n-butil acetate.

Uses: n-butil acetate is used as a solvent in the production of nitrocellulose varnishes, fabrics, artificial leather and plastics, as an extractant in the petroleum and pharmaceutical industries, and also used in spice compounding and banana, pineapple, apricot, pear and other fragrances Ingredients. butil acetate is a colorless and difficult to evaporate compound. butil acetate is commonly used as a solvent in various industries, including paint and coating industries, inks, care products, perfumes and cosmetics. In addition, butil acetate is also used as a solvent in the extraction process and the pharmaceutical industry. butil acetate is obtained by using a catalyst to perform an esterification reaction between butanol and acetic acid. The production process of butil acetate is continuous. The reason for choosing a continuous process is because it allows mass production and therefore improves the quality of the product.

It is an excellent organic solvent that can dissolve rosin, polyvinyl acetate, polyacrylate, polyvinyl chloride, chlorinated rubber, polymethyl methacrylate, etc. It can be used as analytical reagent, chromatographic standard and solvent. It is a common organic solvent for determining antimony, tin, tungsten, molybdenum, antimony and antibiotic extractants.
