実験手順

Hydrogen chloride was introduced at 70° C. for 5 hours into a mixture of 106 g of m-xylene, 531 g of 16N hydrochloric acid and 39 g of paraformaldehyde. Subsequently, the organic phase was separated off and distilled. In the boiling range of from 96° C. to 100° C. at a pressure of 16 mb, 105 g (0.68 moles) of 2,4-dimethylbenzyl chloride, corresponding to 65% of the theoretical yield, were obtained.
