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.
Toluene (or methylbenzene) is a common chemical found in chemistry laboratories. An alkylbenzene is a chemical compound that contains a monocyclic aromatic ring attaching to one or more saturated hydrocarbon chains. [1] Alkylbenzenes are derivatives of benzene, in which one or more hydrogen atoms are replaced by alkyl groups.
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
There weren’t any surprises in the first set of rankings for the 12-team College Football Playoff. Oregon was the No. 1 team ahead of Ohio State, Georgia and Miami.
Toluene is now often used as a substitute for benzene, for instance as a fuel additive. The solvent-properties of the two are similar, but toluene is less toxic and has a wider liquid range. Toluene is also processed into benzene. [69] Major commodity chemicals and polymers derived from benzene. Clicking on the image loads the appropriate article
