采用多种物理方法研究了七种不同原油的沥青质馏分、四种原油的胶质馏分、一种沥青质和一种重质沥青质。通过这些方法中的每一种测量的分子量用于形成关于沥青材料的宏观结构的假设。不同的分子量测量结果的解释是由一个沥青“分子”组成的个人片，其中关联形成单位细胞和较大的相关胶束。胶质在大小上与相应的沥青质馏分相似，但在冷凝程度上不同。本文根据目前的观测结果和前人的数据，提出了一个沥青宏观结构模型。
The asphaltene fractions from seven different native crude petroleums, the resin fractions from four of these crudes, one gilsonlte asphaltene, and one asphaltene from a heavy asphaltic oil were investigated by a variety of physical methods. The molecular weights measured by each of these methods were used to form a hypothesis about the macrostructure of the asphaltic material. The divergent results of molecular weight measurement are explained by an asphalt “molecule” composed of individual sheets, which associate to form unit cells and larger associated micelles. Resins are similar to the corresponding asphaltene fractions in size but differ in the extent of condensation. A model for the macrostructure of asphaltics based on the present observations and previous data Is presented.
