AI Article Synopsis
- Strong temperature-dependent low-angle X-ray scattering was observed in mixtures of trifluoroethanol and hexafluoro-2-propanol with water, under conditions similar to those used in NMR studies on peptides.
- The scattering results suggest that there may be two main molecular effects at play: the formation of clathrate hydrate-like aggregates of alcohol with water, similar to findings in tert-butanol-water systems.
- Additionally, there is an increased heterogeneity in the solution due to the immiscibility of the two alcohol components.
Article Abstract
Strong temperature dependent low angle X-ray scattering by trifluoroethanol- and hexafluoro-2-propanol-water mixtures was observed in conditions commonly used in NMR work on peptides. At least two types of molecular effects may contribute to the observed scattering: formation of clathrate hydrate-like aggregates of alcohol with water as have been proposed for the similar system tert-butanol-water (Iwasaki, K. and Fujiyama, T. (1976) J. Phys. Chem. 81, 1908-1912) and a further heterogeneity of the solution resulting from immiscibility of the two components.
