摘要

原油中含盐不仅影响原油的品质，而且腐蚀设备。本文研究了一种复合枝型聚醚衍生物，在非极性的连续相中能形成极性基团朝内的反胶束状态，利用反胶束体系中形成的“水池”可以溶解水相中的极性物质，从而分离原油中水溶性杂质，利用这种性质，能有效地把原油中的盐脱除掉。该复合枝型聚醚衍生物还可以有效地降低高矿化度水的表面张力，其耐矿化度最高可达200000 mg·L-1，因此可以在海水中作为洗涤剂使用，而且其特有的枝型结构可以有效地抑制海水对金属表面的腐蚀。

Abstract

Salt influence the quality of crude oil and equipment.Branch-composite polyether derivative is studied which forms reverse micelles in non-polar continuous phase.With the advantage that the pool in reverse micelles can dissolve polar materials

water-soluble impurities and salt can be separated from crude oil.The branch-composite polyether derivative can reduce the surface tension of high-salinity water and its salt-resistance is up to 200000 mg·L-1.Thus it can be used in salinity water washing. Moreover

the branch-composite polyether derivative can inhibit the corrosion of metal in salt water effectively.
