The technological value of the coal tar electrode pitch is largely determined by the high content of condensed polyaromatic compounds in its composition. An attempt to change the chemical composition of the coal tar electrode pitch in order to reduce the content of carcinogenic polyaromatical hydrocarbons (PAH) will bring it closer to oil binders that are significantly inferior in their technological properties, or inform them of the new properties that are not desirable from the consumer's point of view. Involving carcinogenic PAH in the process of chemical transformations the products of which are not determined by analytical methods as indicators of cancer risk, will not necessarily lead to a decrease in the carcinogenic risk of coal tar pitch as a physicochemical system.
