FIELD: technological processes.
SUBSTANCE: invention relates to method for producing a binder for production of electrode materials used in production of aluminum. Method for producing a binder pitch with a reduced content of benzo(a)pyrene is described, comprising the thermal treatment by co-distillation of a coal tar with an extract of coal in a ratio of 90:10 to 60:40 by weight at a temperature of not more than 410 °C in the liquid phase.
EFFECT: expansion of raw material base for production of binder pitch, reduction of benzopyrene content, improvement of binder performance characteristics.
