m ‐Xylene is chlorinated with molecular chlorine supplied at a constant flow rate, utilising short chain alcohols as solvents. Chlorinations occur as fast and clean substitution reactions, giving very high yields of monochloro derivatives. o ‐Xylene and p ‐xylene in ethanol give, however, much lower yields, similar to those of catalysed chlorinations. The behaviour of benzene, some other alkylbenzenes, and mixtures of xylenes in ethanol is also studied. In the mixtures, m ‐xylene is very selectively chlorinated and almost quantitatively converted into monochloro derivatives.
