Application of Hexane
Hexane is an organic solvent with good viscosity, commonly used in the rubber, food, pharmaceutical, perfume, shoemaking, tape, ball making, grinding, leather, textile, furniture, and paint industries, as well as for dilution, cleaning, and adhesives. It is also used as a solvent in the extraction of seed oils (such as soybean oil, cottonseed oil, flaxseed oil, peanut oil, and safflower oil); and as a raw material for manufacturing polymers such as polypropylene and polyethylene.
Determining refractive index of minerals; filling for thermometers instead of mercury, usually with a blue or red dye; extraction solvent for oilseed processing.
Suitable for HPLC, spectrophotometry, environmental testing.n-Hexane is a chief constituent of petroleumether, gasoline, and rubber solvent. It is usedas a solvent for adhesives, vegetable oils,and in organic analysis, and for denaturingalcohol.
