Application
n-Butanol, also called 1-Butanol or Butan-1-ol, is a so called Alkanol. n-Butanol is a colorless liquid with typical odor, which is usually classified as tart and wine-like or, as banana aroma. Unlike other solvents, it is freely miscible with the many products in this category. This also applies to water-n-butanol mixtures up to 20% by weight.
n-Butanol is usually used as a solvent in the production of varnishes and paints. In this process, it prevents uneven drying of paints, especially in humid environments. In addition, n-butanol is used as a base for the production of various ethers and esters, such as butyl acetate and glycol butyl ethers and esters, as well as phthalates and acrylates. These are also typically used as solvents or plasticizers. In addition, n-butanol serves as a solvent for dyes, as a textile auxiliary, and is often an additive for polishes and cleaning agents and also component in some fuels.

Further information
In the 1960s, n-butanol was the main ingredient in a well-known dental preparation used to stop bleeding during tooth extractions. Due to the lack of scientific studies and some risk in treating patients holistically, the product was withdrawn from the market in Europe in the early 1980s. However, it is still available in the U.S. as Revici Injection and Revici-e .
