| description | A composition comprising one or more siloxane cross-linked demulsifiers wherein said siloxane cross-linked demulsifiers are prepared by reacting one or more alkylphenol-formaldehyde resin alkoxylates, one or more polyalkylene glycols, or a mixture thereof, with up to about 1.0 molar equivalents of one or more silicon-based cross-linkers of formula R1R2R3R4Si wherein R1, R2, R3, R5, R6 and R7 are independently selected from H, Cl, C1-C4 alkyl and C1-C4 alkoxy; R4. is selected from H, Cl, C1-C4 alkyl, C1-C4 alkoxy and a group of formula L1SiR5R6R7; L1 is absent or is selected from -O-, arylene and C1-C12 alkylene, optionally interrupted by one or more -O- or -N(R8)-; and R8 is H or C1-C4 alkyl and a method of using the demulsifier composition to resolve water-in-oil emulsions. |
