FIELD: oil refining industry.
SUBSTANCE: invention relates to the oil refining industry, in particular to hyperbranched polymers (dendrimers) and demulsifiers based on them used for separation of water-oil emulsions, a method for preparing these compounds, their application, and a method for the destruction of water-oil emulsions. High-molecular hyperbranched polymer (dendrimer) has the general formula 1, in which i is a number of glycidyl links, i=5, 10; m is a number of end links of ethylene oxide; n is a number of end links of propylene oxide provided that n=0, m=100 or n=100, m=0 or n=100, m=100.
EFFECT: increase in the efficiency of demulsification of water-oil emulsions (desalination and dehydration).
