Toluene /ˈtɒljuːiːn/, formerly known as toluol /ˈtɒljuːɒl/, is a colorless, water-insoluble liquid with the smell associated with paint thinners. It is a mono-substituted benzene derivative, consisting of a CH3 group attached to a phenyl group. As such, its IUPAC systematic name is methylbenzene. It is an aromatic hydrocarbon.
Toluene is widely used as an industrial feedstock and as a solvent. Like other solvents, toluene is sometimes also used as an inhalant drug for its intoxicating properties; however, inhaling toluene has potential to cause severe neurological harm. Toluene is an important organic solvent. Its economic significance is considerable: In 2013, worldwide about 24.5 billion US-dollars were generated with the sale of toluene.
The compound was first isolated in 1837 through a distillation of pine oil by a Polish chemist named Filip Walter, who named it rétinnaphte. In 1841, French chemist Henri Étienne Sainte-Claire Deville isolated a hydrocarbon from balsam of Tolu (an aromatic extract from the tropical Colombian tree Myroxylon balsamum), which Deville recognized as similar to Walter's rétinnaphte and to benzene; hence he called the new hydrocarbon benzoène. In 1843, Jöns Jacob Berzelius recommended the name toluin. In 1850, French chemist Auguste Cahours isolated from a distillate of wood a hydrocarbon which he recognized as similar to Deville's benzoène and which Cahours named toluène.
April Rain
How does it feel when all you're counting on is scatterbrained
Every wind that you have sailed upon, a hurricane
Every summer you have seen was filled with April rain
It doesn't get easy, don't you know
Fortune smiles on you
You're not watching, dig that hole deeper
Fortune smiles on you
You're not watching, create your own fate
Count your blessings and prepare to change your point of view
All those days that you spend waiting won't come back to you
Take off the glasses that have treated your world black and grey
It doesn't get easy, don't you know
Fortune smiles on you
You're not watching, dig that hole deeper
Fortune smiles on you
You're not watching, create your own fate
Keep raining
'Cause we are blind, 'cause we are tired, 'cause we are blind to fortune's guidance now
It keeps raining, 'cause we are blind, it will keep raining, 'cause we are tired
It keeps raining, 'cause we are blind oh, it will keep raining 'cause we are tired
Fortune smiles on you
You're not watching, dig that hole deeper
Fortune smiles on you
