摘要
用Ｌａｎｇｍｕｉｒ－Ｂｌｏｄｇｅｔ技术测试了一系列沥青质膜、胶质膜的π－Α等温曲线。结果表明，原油中的沥青质和胶质在空气－水界面均形成不溶性膜；沥青质膜的性质随扩展溶剂芳香性的不同而不同，胶质膜的性质与沥青质膜有较大差异；
A series of π A isotherm measurements were performed to study the properties of the films of asphaltenes and resins spread from different solvents.It showed that asphaltene and resin can form a two dimensional insoluble film on an air water interface.The properties of interface films of asphaltenes are quite different with the variation of the aromaticity of spread solvents and related to the states of asphaltenes in solvents.The effects of resins and the aromaticity of solvents on its solvency behavior were compared.
