FIELD: chemistry.
SUBSTANCE: composition for the treatment of cross ties, which contains the fraction of heavy gas oil of the slowed down coking with the flash temperature not below 110°C, formed during coking tar of the fuel oil vacuum distillation unit, or its mixture with resin of the pyrolytic production of ethylene, propylene, or its mixture with the resin of the pyrolytic production of ethylene, propylene and heavy gas oil of catalytic cracking, or its mixtures with resin of the pyrolytic production of ethylene, propylene, heavy gas oil of catalytic cracking and an extract of the selective purification of oils in the quantity 5-25 mass% and the heavy remainder which boils away within the limits of 190-500°C, with the flash temperature not below 100°C, formed during the distillation of the mixture of the trap petroleum products, obtained after sedimentation of drainage waters of commercial products, after sedimentation of petroleum refinery waste waters and sewage of manufacture of oils, after sedimentation of marketable-raw parks, trap petroleum product of the delayed coking unit, trap petroleum product of the manufacture of oils with the involvement of the waste petroleum-containing products, a gas condensate, "black solar oil" of bituminous installation, the weighted component of diesel fuel of installations of the primary oil refining and which boils away within the limits of 60-500°C, in the quantity 75-95 mass%.
EFFECT: higher operational characteristics and expansion of the assortment of preservative oil liquids and raw-material base for their manufacture.
