Particulated polyether:A novel defoamer for nonaqueous foams
摘要
Abstract
Using triblock copolymer poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide)and citric acid as raw materials,a novel polyether was synthesized through condensation-carbonization under high temperature,which had a hyperbranched structure using nanocarbon as the core,or crosslinked morphology connected by nanocarbon.The mixture of triethanolamine monooleate/p-xylene was selected as a model system to produce nonaqueous foam.It was found that the synthesized polyether had a high defoaming efficiency up to 86%within 30 min,demonstrating a defoaming rate over 2 000 times that of the defoamer-free system.Furthermore,the crude oil from Gudao oil production plant was foamed under high pressure of CO2.The polyether also showed good defoaming efficiency to this foam of crude oil.Our work might provide a new strategy to synthesize nanocarbon-hybridized polyether,which could find applications in cases where defoamers based on organosilicone could hardly be used on a large scale,e.g.,the foamed oil produced by the oilfield auxiliary chemicals that are intensively used during oil exploitation.关键词
