Fundamental Properties of Tetra-n-Butyl Ammonium Bromide Aqueous Solutions

－1st Report: Refractive Index, Density and Viscosity－

Abstract

Since the occurrence of the Tohoku Region Pacific Coast Earthquake on March 11 in 2011, peak load reduction of the daytime electric power has been more important in Japan. One of the efficient measures against the daytime peak load reduction in hot season is to use appropriate thermal storage system at the nighttime. Tetra-n-Butyl Ammonium Bromide (TBAB) organic hydrate slurry is being used to facilitate the development- and application-related advancements in thermal storage and air-conditioning systems. The fundamental thermophysical properties of the TBAB aqueous solutions; refractive index, density and viscosity, as well as the empirical equations of these properties, are presented in this paper.
