The possibility of petroleum residues (tar and oxidized bitumen) modification with formaldehyde (37 % aqueous solution) has been studied at the temperature 393±3 K for 3 h in presence organic solvent using hydrochloric acid as a catalyst. Toluene, p-xylene, naphta n-octane were used solvents amount 0–40 wt relative to initial material. By means IR spectroscopy resin-like compounds affecting operational properties have detected. These are formed result reaction residue components molecules.
