✦ Synopsis


Carboxylic acids, acid anhydrides and N-hydroxy methylamides were used to acylate Assam coal under Friede!-Crafts reaction conditions. This reaction resulted in the enhancement of the extractability of coal in benzenmethanol (7:3 vol./vol.) and quinoline after acylation with carboxylic acids and acid anhydrides.Theeffect of catalyst (AICI,) concentration on reaction wasalso investigated. 1.1. spectra of reaction products indicated the introduction of acyl groups in the coal structure. Phthalimidomethylation could render about 5% coal extractable in quinoline.

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
