What is the difference between toluene and xylene?

hydrocarbons are only carbon and hydrogen compounds and can be divided into two types: aliphatic hydrocarbons and aromatic hydrocarbons. It has multiple bonds plus a special type of stabilization called aromaticness that modifies the way chemically interacts. Toluene and xylene are aromatic hydrocarbons, derivatives of benzene, with its chemical formula C _{6 6 . Skeleton atoms in benzene is what resembles a Russian bike, with six hydrogen atoms corresponding to cars. The benzene turns into toluene and xylene by replacing the hydrogen atoms with methyl groups (ch 3 -). Only one hydrogen atom is replaced by a methylem in toluene, which has a chemical formula C 6 h 5 . Although there are six carbon atoms in the benzene circle, all are the same chemically as the symmetry suggests. For this reason, it does not matter Tomich carbon Methyl Group combines, because the result is the same in any case. No need for atoms of carbon toluene with a ring because every mo moThe toluene pellene is identical, which simplifies processing because there are no isomers that should be separated.}

xylene is a di-substitated benzene, with two methyl groups replacing two hydrogen atoms. In fact, there are three different types or isomers of xylene. Atoms in the benzene circular part of the structure are marked as one to six. Starting with the upper ring carbon and walking clockwise, three varieties are ortho-xylene or 1, 2-dimethylbenzene; meta-xylene or 1, 3-dimethylbenzene; and para-xylene or 1.4-dimethyl benzene. Part of the benzene ring each structure is written

Benzene has excellent solvent properties for many applications. Unfortunately, benzene damages the ability of the HT fig. Toluene and xylene are particularly important as spare solvents for benzene. These substances are not only used as a solventand; As shown by the known "TNT" letters, toluene is used in the production of powerful explosive trinitrotoluene. Another useful toluene derivative is produced by a simple oxidation of its methyl group, resulting in benzoic acid, commercially important preservative.

xylenes can be used together, such as "xylol" or "mixed xylens" or can be used individually. As with benzene and toluene, xylene is used as solvents. In synthesis, the ortho and para-isomers of xylene may have oxidized methylic side chain to form important acids of dicarboxylic, tephtalic acid and orthophtala acid. Ftal acids are used in the production of polyesters, alkyd resins and plasticizers. They are also used in the production of special chemicals such as anthrachinone and phenolphtalein.
