1-Butanol CAS#71-36-3

n-Butyl alcohol is a colourless flammable liquid with sturdy alcoholic odour. n-Butyl alcohol is a fantastically refractive liquid and burns with a strongly luminous flame. It is incompatible with robust acids, sturdy oxidising agents, aluminium, acid chlorides, acid anhydrides, copper, and copper alloys. n-Butyl alcohol has an considerable use in a giant quantity of industries. For instance, it is used as solvent in industries related with the manufacturing of paints, varnishes, artificial resins, gums, pharmaceuticals, vegetable oils, dyes, and alkaloids. n-Butyl alcohol finds its use in the manufacture of synthetic leather, rubber, plastic cements, shellac, raincoats, perfumes, and photographic films.

Product Usage

1-Butanol is the most vital and broadly studied alcohol in industry. It is a colorless liquid with a robust and slight alcohol smell. It is used for chemical derivatives and is additionally used as a solvent for paints, waxes, brake fluids, and detergents.
It is in the main used to make n-butyl plasticizers such as phthalic acid, aliphatic dicarboxylic acids, and phosphoric acid, and is broadly used in a number of plastics and rubber products; it is used as a uncooked cloth for the manufacturing of butyraldehyde, butyric acid, butylamine, and butyl lactate in natural synthesis; it is an extractant for petroleum, pills (such as antibiotics, hormones, vitamins, etc.), and spices, and an additive for alkyd paints; it is a solvent for natural dyes and inks, a dewaxing agent, etc.
