WebJan 1, 1989 · The reactant mixture of benzene and 2-chloropropane was prepared by passing two dry nitrogen streams through individual benzene and 2-chloropropane evaporators and mixing the streams in a mixer. The flow-rate of 2-chloropropane was 1 mmol h and the benzene-to-2-chloropropane ratio was controlled in the range 0.9 to 4.1. WebBenzene reacts at room temperature with a chloroalkane (for example, chloromethane or chloroethane) in the presence of aluminium chloride as a catalyst. On this page, we will look at substituting a methyl group, but any other alkyl group could be used in the same way. Substituting a methyl group gives methylbenzene. or: WebMay 7, 2024 · So if you mix AlCl 3 with benzene, the "reaction" just goes to a complex and awaits further reactant. Perhaps the Cl atom on an alkyl chloride or on a Cl 2 molecule is more electron-donating than the benzene ring and favors formation of an alkyl cation in some form.
