Description
Summary:The peculiarities in methanol action during liquefaction of coals having different origin and rank were investigated. When liquefying sapropelic coals, the action of methanol does not differ from that of toluene. In the case of humic coals, methylation of aromatic fragments takes place and methylated liquid products are produced. The degree of alkylation increases with decrease in coal rank. The alkylation of model coal substances and some polyaromatic hydrocarbons was small. It was concluded that during coal liquefaction, reactive coal intermediates are subjected to alkylation.
