原油破乳剂,通常是一些低分子量共聚物,这些共聚物的分子量和分子量分布对原油破乳剂的质量有一定的影响。用凝胶色谱渐近法校正,直接测定AE型原油破乳剂分子量及其分布,国外有关这方面的工作报道尚不曾多见,国内的研究与应用刚刚在开始。本文采用凝胶色谱法,用宽分布标样 Crude oil demulsifiers, usually low molecular weight copolymers, whose molecular weight and molecular weight distribution have some influence on the quality of crude oil demulsifiers. The calibration of gel chromatography asymptotic method was used to directly determine the molecular weight and distribution of AE type crude oil demulsifier. The work reports in this field in foreign countries are yet to be seen. The domestic researches and applications are just beginning. In this paper, gel chromatography, with a wide distribution standard
