N-butyl acetate, also known as n-butyl acetate, is an organic compound. It is widely used in the paint industry. It is often used as a solvent to help dissolve resins, pigments and other components, so that the paint has good coating performance and drying speed, and can give the coating a flat and smooth appearance. In the ink industry, it also plays an important role as a solvent to ensure that the ink has suitable viscosity and drying characteristics, thereby improving printing quality. In addition, in the fragrance industry, it can be used as a fragrance ingredient to add a unique aroma to the product.

N-butyl acetate has many properties. Its appearance is a colorless transparent liquid with a fruity aroma. The boiling point is about 126.1 ° C, and the relative density (water = 1) is 0.88. It is slightly soluble in water and miscible with most organic solvents such as alcohols and ethers. It has certain chemical stability, but under specific conditions, reactions such as hydrolysis and alcoholysis can occur.

Regarding its production, the common method is esterification. Using acetic acid and n-butanol as raw materials, under the action of concentrated sulfuric acid and other catalysts, n-butyl acetate is formed by heating and reflux reaction. During the reaction process, the temperature, raw material ratio and catalyst dosage need to be precisely controlled to improve the yield. After the reaction, high-purity n-butyl acetate products are obtained through a series of refining processes such as distillation, washing with water, and drying. In addition, other production processes continue to emerge, aiming to improve production efficiency, reduce energy consumption and environmental pollution.
