Viscosity of Neopentane

Abstract

The viscosity of neopentane has been measured between −15°C and 30°C. These results are consistent with published work covering the temperature range 30°C to 150°C. The viscosity data for neopentane have been compared with similar data for the other pentanes. This comparison has provided an example of the importance of molecular shape for viscosity behavior. The possible significance of molecular shape for the interpretation of viscosity curves of binary mixtures is noted. Finally, it has been suggested that further work on liquids composed of spherical molecules might be worthwhile.
