Polyoxyethylene glycol fatty acid ester계 유분산제의 제조와 Weathering Crude Oil에 대한 분산효율 특성

Preparation of Polyoxyethylene glycol fatty acid ester oil dispersant and dispersion efficiency on Weathering crude oil

Polyoxyethylene monooleate was prepared by addition of ethylene oxide to oleic acid. And also, polyoxyethylene monooleate type oil dispersant was prepared by blending polyoxyethylene monooleate, n-paraffine, sorbitan monooleate, sorbitan monopalmitate, and palm oil. Dispersion efficiency test was carried out by vertical shaking flask and swirling flask methods. Low toxic oil dispersant was prepared with polyoxyethylene monooleate, which has high biodegradability and excellent dispersion efficiency on crude oils and weathered W/O emulsions with high viscosity, and its dispersion efficiency was measured to various crude oils and weathered oils.
