摘要：

Water soluble nonionic surfactants based on Schiff base monomers were prepared by their etherification with beta,beta- dichlorodiethylether and PEG 400 in presence of NaOH. The surface properties of the prepared surfactants were determined by measuring the surface tension at different temperatures. The prepared nonionic surfactants were evaluated as demulsifiers for synthetic water in crude-oil emulsions that were pronounced at different ratios of crude oil: water at 45 degrees C and 60 degrees C. The experimental results showed that the dehydration rate of the prepared demulsifiers reached 90% and 100% at some concentrations.
