Constituting 85% of its use, 1-butanol is mainly used in the production of varnishes. It is a popular solvent. A variety of butyl esters are used as solvents, e.g. butoxyethanol. Many plasticizers are based on butyl esters, e.g., dibutyl phthalate. The monomer butyl acrylate is used to produce polymers. It is the precursor to n-butylamines.
