Abstract
Within the framework of green chemistry principles, the concept of deep eutectic solvents (DES) was used to develop solid commercial forms of oil-displacing compositions. It has been shown that the eutectic composition on the phase diagram of the binary system ammonium salt - carbamide corresponds to DES as the basis of solid commercial forms of oil-displacing composition with the best physicochemical and technological characteristics. The optimal concentrations of solid commercial forms in the working solution of the composition were determined for the ternary DES system ammonium salt - carbamide - water. The results of laboratory studies and field tests of the working solution based on the solid commercial forms of the oil-displacing composition are presented.
