What is Toluene and Its Origin?

Why is Toluene found in the environment?

Toluene is identified as a natural constituent of crude oil, being found within the tolu tree which gave toluene its name. Its natural occurrence is also verified through the emissions of small quantities through volcanic activities and forest fires. These activities, along with the natural occurrences of oil, are the contributors towards the presence of Toluene in the environment. However, toluene is most commonly extracted from petroleum fluids after further industrial refinement and processing which includes Nitration of toluene.

Where can Toluene be found?

Toluene is widely known, being present in gasoline which is used to fuel vehicles, as well as used in certain indeustrial activities as a solvent oil. Many industrial products such as paints, paints thinners, adhesives and cleaning products contain toluene. To add on, during the industrial refinement of Petroleum, Toluene is released and was discovered to be a byproduct while producing coke with coal.

Is toluene related to benzene in any way?

Both toluene and benzene are related to toluene because, like toluene, they are aromatic hydrocarbons that have a six-carbon benzene ring. However, toluene and benzene differ in molecular composition. Ethyl benzene (C6H5C2H5) is a methyl-substituted derivative of benzene with the -C2H5 functional group attached. Toluene has the IUPAC name methylbenzene. As its name suggets, toluene is a methyl-substituted derivative of benzene and its formula is C6H5CH3, which means one hydrogen atom in the benzene ring have been replaced by a methyl group (-CH3).

More practical chemicals in these compounds are therefore less toxic like toluene or even harmless like benzene; however, caution must be taken while dealing with them. Due to prolonged exposure to benzene, it can have severe damage such as leukemia and some other blood disorders making it a well known human carcinogen. Toluene is relatively less toxic but could still be very dangerous without precautions, these qualities allow toluene to be used industrially as a much safer alternative like solvent or fuel additive.

Both compounds appear as clear liquid without color and possess fragrant smell. Their boiling point, solubility in water, density, and other features vary slightly. For example, the boiling point of benzene is about 80.1ºC (176.2ºF), and for toluene it is higher – 110.6ºC (231ºF). Also, benzene has greater solubility in water than toluene, which allows it to diffuse in the environment easily.

The chemical reactivity of toluene is also distinct because methyl group affords it additional reactions of side chain oxidation and electrophilic substitution at the methyl position. Such differences in chemical structures and behaviors make toluene industrially useful while, at the same time, being different from benzene in safety and uses.

What is the Melting Point of Toluene and what is its purpose?

How does the melting point affect its use as a solvent?

The melting point of toluene is around -95 degrees Celsius (-139 degrees Fahrenheit). This low melting point allows toluene to maintain a liquid state under fairly extreme environmental conditions. This makes its use as a solvent practical and efficient.
