Toluene is widely used in the paint, dye, rubber, chemical, glue, printing, and pharmaceutical industries as a solvent. [38] Nail polish, paintbrush cleaners, and stain removers may contain toluene. Manufacturing of explosives (TNT) uses it as well. Toluene is also found in cigarette smoke and car exhaust.
Ethyltoluenes are prepared by alkylation of toluene with ethylene: CH 3 C 6 H 5 + CH 2 =CH 2 → CH 3 C 6 H 4 CH 2 CH 3. These alkylations are catalyzed by various Lewis acids, such as aluminium trichloride. 3- and 4-Ethyltoluenes are mainly of interest as precursors to methylstyrenes: CH 3 C 6 H 4 CH 2 CH 3 → CH 3 C 6 H 4 CH=CH 2 + H 2
[42] [43] [non-primary source needed] The action of BHT in these is akin to the action of many other organic compounds, e.g., quaternary ammonium compounds, phenolics, and detergents, which disrupt viruses by insertion of the chemical into the virus membrane, coat, or other structure, [44] [45] [46] which are established methods of viral ...

In the petroleum refining and petrochemical industries, the initialism BTX refers to mixtures of benzene, toluene, and the three xylene isomers, all of which are aromatic hydrocarbons. The xylene isomers are distinguished by the designations ortho – (or o –), meta – (or m –), and para – (or p –) as indicated in the adjacent diagram.
Instead, it uses the wind to fly more than 600 miles a day. Researchers at MIT are using this flight design to develop drones. ... Solar panels inspired by the structure of plant leaves capture ...
The simplest member, toluene (or methylbenzene), has the hydrogen atom of the benzene ring replaced by a methyl group. The chemical formula of alkylbenzenes is C n H 2n-6. [2] Safety hazards of toluene. Oftentimes, toluene is used as an organic solvent.
Water is a solvent for polar molecules, and the most common solvent used by living things; all the ions and proteins in a cell are dissolved in water within the cell. Major uses of solvents are in paints, paint removers, inks, and dry cleaning. [ 2 ]
