Toluene is named after an old name  toluol. Toluene is an aromatic hydrocarbon and is found largely in coal tar. Toluene is a light and flammable liquid used as a solvent in various industries such as paints and resins. It is an organic material. Its chemical formula is C6H5CH3, and it can be produced from the reaction of methyl iodide (CH3I) with benzene and aluminum chloride (AlCl3) in vitro. Toluene is a smooth, water-insoluble liquid that is similar to the odor of ordinary paint thinners. According to the contact time of this material, it may cause mild or severe eye and skin irritation with skin and eyes. The main influence of this substance on the central nervous system is.

The name of toluene is taken from the old name of Toluol, Toluene is an aromatic hydrocarbon 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). Toluene (Methylbenzene or Phenylmethane) is a liquid that is insoluble in water with a similar odor to conventional odor thinners. Toluene is a group of aromatic compounds and is used as an initial material as well as a chemical solvent. Other uses include the color solvent, paint thinner, silicone sealant, chemical reactive agent, plastic, printing ink, glue, varnish and disinfectant and disinfectant. It can also be used to make foam and TNT. An interesting point about toluene is its use as an inhaler for detoxification. Low to moderate toluene concentrations, fatigue, dizziness, weakness, unbalanced behavior, memory impairment, insomnia, chestnut, and loss of vision and hearing. These conditions are reduced by the loss of the presence of toluene. Toluene may affect any adverse effects. There is no evidence that toluene is carcinogenic. Permissible concentrations of 200 ppm for the working environment are recommended by OSHA and mg / l by EPA for drinking water. Toluene can not only enter the human body through inhalation but also from contaminated soils, as it is possible to direct human contact with the soil, drinking contaminated groundwater and evaporating from the soil. Due to the carcinogenicity of benzene, toluene, which has properties similar to benzene, is now used as a substitute. Uses: It is used as a solvent in various industries such as paints and resins  

Physical and chemical properties: 

Molar mass 92.14 g / mol 

Appearance colorless liquid 

Density 0.8669 g / mL 

Melting point -93 C 

Boiling point 110.6 ° C 

Solubility in water 0.47 g / l (20-25 ° C)

Production methods: The production of toluene in laboratory conditions is summarized as follows: Inside a large and resistant test tube, add 2 ml of benzene liquid with a few drops of methyl iodide (CH3I) and 0.4 g of aluminum chloride (AlCl3) powdered Heat slowly until the wet litmus paper on top of the test tube turns blue to red to indicate the end of the reaction.  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 white, 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.  

Safety Information: 

Depending on the duration of exposure, it causes mild or severe eye and skin irritation. The main influence of this substance on the central nervous system is. Toluene is combustible and flammable. The vapors of this material can be exploded when mixed with air.
