FIELD: chemical technology.
SUBSTANCE: invention relates to agents used in destruction of aqueous-petroleum emulsions and can be used in dehydrating petroleum in industrial units in petroleum preparing. The composition for destruction of aqueous-petroleum emulsions and treatment of sewage waters comprises dimethyl phosphite, nitrogen-containing compound, non-ionogenic surface-active substance, Phosphenox H-12, solvent and alkylbenzene sulfoacid in the following ratio of components, wt.-%: dimethyl phosphite, 0.01-2.0; nitrogen-containing compound, 0.2-2.0; non-ionogenic surface-active substance, 25.0-70.0; Phosphenox H-12, 1.0-15.0; alkylbenzene sulfoacid, 0.1-15.0, and solvent, the balance. Invention provides the development of effective de-emulsifying agent of aqueous-petroleum emulsion showing the complex effect for high-viscous oils.
EFFECT: improved and valuable properties of composition.
