有机溶剂如苯乙炔、苯乙烯和乙苯被广泛应用于工业生产，特别是橡胶或热塑性塑料的生产。尽管它们有重要的应用，但关于它们结构的详细知识是有限的。本文用中子衍射法研究了这三种芳香族溶剂的结构。结果表明，与乙苯和苯乙烯相比，苯乙炔的结构更有序，溶剂化球更小，但它们的许多结构特征是相似的。在第一配位球内的两个区域中，每种液体的周围分子相对于中心分子表现出不同的优选取向。此外，脂肪链的定位表明，它们倾向于更紧密地相互作用，而不是与相邻分子的芳香环相互作用。
Organic solvents such as phenylacetylene, styrene and ethylbenzene are widely used in industrial processes, especially in the production of rubber or thermoplastics. Despite their important applications detailed knowledge about their structure is limited. In this paper the structures of these three aromatic solvents were investigated using neutron diffraction. The results show that many of their structural characteristics are similar, although the structure of phenylacetylene is more ordered and has a smaller solvation sphere than either ethylbenzene or styrene. Two regions within the first coordination sphere, in which the surrounding molecules show different preferable orientations with respect to the central molecule, were found for each liquid. Additionally, the localisation of the aliphatic chains reveals that they tend to favour closer interactions with each other than to the aromatic rings of the adjacent molecules.
