Reaction of Aromatic Compounds with a Chlorinated Coal and Aluminium Chloride

Abstract

VAN KREVELEN et al. ¹ have reported on the coupling of pitch molecules by chloromethylation and subsequent condensation under the influence of a Friedel-Crafts catalyst, while Iyengar, Banerjee and Banerjee² have claimed the alkylation of coals with benzyl chloride and aluminium chloride. But in these laboratories a similar type of reaction between a chlorinated low-rank coal (containing about 50 per cent of hydrolysable chlorine) and several aromatic compounds, in the presence of aluminium chloride, has given inconclusive results which suggest that alkylation may not have occurred during the reaction with benzyl chloride.
