n-Butyl alcohol is a colorless flammable liquid with a strong alcoholic odor. It is a highly refractive liquid and burns with a brightly luminous flame. It cannot be used together with strong acids, strong oxidants, aluminum, acyl chlorides, acid anhydrides, copper and copper alloys. n-Butyl alcohol is widely used in many industries. For example, it is used as a solvent in the production of paints, varnishes, synthetic resins, gums, pharmaceuticals, vegetable oils, dyes and alkaloids. It is also used in the manufacture of artificial leather, rubber, plastic cements, shellac, raincoats, perfumes and photographic films.

Product Application of 1-Butanol CAS#71-36-3
1-Butanol is used in the production of butyl acetate, butyl glycol ether, and plasticizers such as dibutyl phthalate. It serves as a solvent in the coating industry, for extracting oils, pharmaceuticals and cosmetic nail products, and as an ingredient in fragrances and flavors. 1-Butanol is found in fusel oil and is a byproduct of the fermentation of alcoholic beverages like beer and wine. It also exists in beef fat, chicken soup and unfiltered cigarette smoke.
