The structure of ethylbenzene, styrene and phenylacetylene determined by total neutron scattering

Research output: Contribution to journalArticle

Abstract

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 organized than either ethylbenzene or styrene. Two regions within the first coordination sphere, in which the surrounding molecules show different preferable orientations with the respect to the central molecule, were found for each liquid. Additionally, the localisation of the aliphatic chains reveal that they tend to favour closer interactions with each other than to the aromatic rings of the adjacent molecules.
