1.  Product Overview

Mainly used to make n-butyl ester plasticizers of phthalic acid, aliphatic dibasic acid . They are widely used in various plastics and rubber products. They are also used in the production of butyraldehyde, butyric acid and butylamine in organic synthesis. and butyl lactate, etc. It is also an extractant for oils, drugs (such as antibiotics, hormones and vitamins) and spices, an additive for alkyd resin coatings, etc. It can also be used as a solvent and dewaxing agent for organic dyes and printing inks.
Butan-1-ol with the chemical formula C4H9OH and a linear structure. Isomers of butan-1-ol are butan-2-ol . The unmodified term butanol usually refers to the straight chain isomer.
1-Butanol is present in many foods and drinks. It is also a permitted artificial flavorant in the United States, used in butter, cream, fruit, rum, whiskey,ice cream and ices, candy, baked goods, and cordials. It is also used in a wide range of consumer products.
The largest use of 1-butanol is as an industrial intermediate, particularly for the manufacture of butyl acetate (itself an artificial flavorant and industrial solvent).

 

Constituting 85% of its use, 1-butanol is mainly used in the production of varnishes. It is a popular solvent, e.g. . A variety of butyl esters are used as solvents, e.g. butoxyethanol. Many plasticizers are based on butyl esters, e.g., dibutyl phthalate. It is the precursor to n-butylamines.
Biofuel
It is produced in small quantities in nearly all fermentations . Clostridium produces much higher yields of butanol. Research is underway to increase the biobutanol yield from biomass.
Butanol is considered as a potential biofuel (butanol fuel). Butanol at 85 percent strength can be used in cars designed for gasolin without any change to the engine (unlike 85% ethanol), and it provides more energy for a given volume than ethanol, due to butanol's lower oxygen content, and almost as much as gasolin. Therefore, a vehicle using butanol would return fuel consumption more comparable to gasolin than ethanol. Butanol can also be added to fuel to reduce soot emissions.
The production of, or in some cases, the use of, the following substances may result in exposure to 1-butanol: artificial leather,rubber cement, dyes, fruit essences, lacquers, motion picture, and photographic films, raincoats, perfumes,
pyroxylin plastics, rayon, safety glass, shellac varnish, and waterproofed cloth.
