Description
Toluene
Toluene is aromatic hydrocarbons and is found largely in coal tar. It is a light and flammable liquid and is used as a solvent in various industries such as paints and resins. Its chemical formula is C6H5CH3, and it can be made in vitro by reacting methyl iodide (CH3I) with benzene and aluminum chloride (AlCl3).
By reducing toluene by a strong oxidant such as potassium permanganate, we can obtain one of the derivatives of toluene (benzene) called benzoic acid. Benzoic acid is a white solid, with a needle-shaped crystal that has anti-mildew properties, and is therefore used in sausage and sausage industry. All benzene derivatives are more or less carcinogenic.
PRODUCT APPLICATION
It is also used as a basic material as well as chemical solvent. Other uses include a color solvent, paint thinner, silicone sealant, chemical reactive agent, plastic, printing ink, glue, varnish, and disinfectant. It can also be used to make foam and TNT.
