Crude coal benzol is produced at the Koks plant. This is a liquid which is extracted from coke oven gas with washing oil. It is widely used in industry; in particular, being a raw material in the production of plastics, rubber and dyes. The main components of crude benzol are benzol and its homologues - toluene, dimethylbenzenes, trimethylbenzenes.
