A study was carried out on aspects of phenomena on the interfacial boundary of acids and hydrocarbon systems of different complexity. These phenomena were evaluated relative to the interfacial tension measured by the pendant drop method. We discovered peculiarities of the interaction of hydrochloric and sulfamic acids with individual hydrocarbons as well as complex hydrocarbon systems. The complex dependence of the interfacial tension on the composition and properties of the hydrocarbon phase, type and concentration of the acid, and the chemical composition of asphaltenes was elucidated.

烃体系与酸相界的界面现象

对不同复杂程度的酸和烃系统界面边界现象进行了研究。这些现象是相对于通过悬滴法测量的界面张力进行评估的。我们发现了盐酸和氨基磺酸与单个碳氢化合物以及复杂碳氢化合物系统相互作用的特性。阐明了界面张力对烃相的组成和性质、酸的类型和浓度以及沥青质的化学组成的复杂依赖性。
