Toluene (/ ˈ t ɒ l. j u iː n /), also known as toluol (/ ˈ t ɒ l. j u. ɒ l , - ɔː l , - oʊ l / ), is a substituted aromatic hydrocarbon [ 15 ] with the chemical formula C 6 H 5 CH 3 , often abbreviated as PhCH 3 , where Ph stands for the phenyl group.

Industrially, the diazonium method is reserved for 3-chlorotoluene. The industrial route to 2- and 4-chlorotoluene entails direct reaction of toluene with chlorine. The more valuable 4-chlorotoluene is separated from 2-chlorotoluene by distillation. Distillation cannot be applied to separating 3-chlorotoluene from 4-chlorotoluene. [2]
Dichlorotoluenes are organochlorine compounds, in particular aryl chlorides, with the formula CH 3 C 6 H 3 Cl 2. Six constitutional isomers exist, differing in the relative position of the two chlorine substituents around the ring. They are all colorless and lipophilic. The 3,5 isomer is a solid at room temperature, whereas the others are liquids.
2 FeCl 3 + C 6 H 5 Cl → 2 FeCl 2 + C 6 H 4 Cl 2 + HCl. iron(III) chloride releases chlorine gas when heated above 160 °C, generating ferrous chloride: [16] 2FeCl 3 → 2FeCl 2 + Cl 2. To suppress this reaction, the preparation of iron(III) chloride requires an excess of chlorinating agent, as discussed above. [16] [10]

An alternative synthesis of anhydrous ferrous chloride is the reduction of FeCl 3 with chlorobenzene: [5] 2 FeCl 3 + C 6 H 5 Cl → 2 FeCl 2 + C 6 H 4 Cl 2 + HCl. For the preparation of ferrocene ferrous chloride is generated in situ by comproportionation of FeCl 3 with iron powder in tetrahydrofuran (THF). [6]
