DEMULSIFYING COMPOSITION AND A METHOD OF ITS USE Russian patent published in 2018 - IPC B01D17/05 C10G33/04 

FIELD: chemistry.

SUBSTANCE: invention is aimed to the create an environmentally friendly demulsifying composition containing low levels of surfactants in environmental responsible solvent bases or bases similar to oil components and consistent with cationic surfactants present in other oil treatment chemicals. Demulsifying composition comprising a mixture of cyclic oxyalkylated alkanes in an amount of at least three components is described, total content of which in a mixture is not less than 80 % by weight, obtained by reduction and subsequent oxyalkylation with ethylene oxide and propylene oxide from 2-(6,6-dimethylbicyclo[3.1.1]hept-2-en-2-yl)ethanol, 2-(7,7-dimethylbicyclo[4.1.0]hept-3-en-3-yl)ethanol, 2-(4-(prop-1-en-2-yl)cyclohex-1-en-1-yl)ethanol, formed as a result of the Prins reaction, the rest is gum turpentine. There is also described a method for a water-oil emulsion breaking.

EFFECT: demulsifying composition suitable for the water-oil emulsion breaking is obtained.
