The miscibility properties of branched phosphatidylcholines in mixtures of aqueous dispersions were studied by means of differential scanning calorimetry. The phase diagrams of four pseudo-binary systems from mixing type unbranched phosphatidylcholine/branched phosphatidylcholine/water (50 wt. % water) were investigated and discussed. The unbranched dipalmitoylphosphatidylcholine acts as a reference component of the mixtures. The phase diagrams of these four pseudo-binary phosphatidylcholine systems showed some connections between chain structure of the branched phosphatidylcholines and miscibility of the components. A change of the phase diagram type has been observed according to the branching and/or chain length differences of the phosphatidylcholines: complete miscibility and peritectic mixing behaviour. Generally we observed complete miscibility in the high-temperature phase (La-phase) and demixing in the low-temperature phases (gel phase). This is dependent on the branching and chain length differences of the mixing components.
通过差示扫描量热法研究了支链磷脂酰胆碱在水分散体混合物中的混溶特性。研究并讨论了由直链磷脂酰胆碱/支链磷脂酰胆碱/水（50 wt.%水）混合类型组成的四个伪二元体系的相图。直链二棕榈酰磷脂酰胆碱作为混合物的参考成分。这四个伪二元磷脂酰胆碱体系的相图显示了支链磷脂酰胆碱的链结构与各组分混溶性之间的一些联系。根据磷脂酰胆碱的分支和/或链长差异，观察到相图类型发生了变化：完全混溶和包晶混合行为。一般来说，我们观察到在高温相（La相）中完全混溶，在低温相（凝胶相）中发生分层。这取决于混合组分的分支和链长差异。
