Nonideality of water-hexafluoropropanol mixtures as studied by X-ray small angle scattering.

S Kuprin1, A Gräslund, A Ehrenberg, M H Koch.   

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.
