Four bituminous coals of different rank were acylated with aliphatic acyl chlorides using Friedel-Crafts catalysts. A dry steam coal and a coking coal showed particularly good reactivity, five acyl groups being inserted per 100 carbon atoms. Compared with the initial coal, the acyfated coats were di
