Abstract
The object of this paper is experimental discussion on dispersion rate by analogy with the theory of chemical rate processes, the calculation of rate constant k and so on. The apparatus consists of a cylindrical vessel (150 mmφ) and Rushton-type impeller (49 mmφ). Water and a mixture of n-C7H16 and CCl4 were used as the continuous phase and the dispersed phase, and still more Tween-20 was used as emulsifying agent. The photographs of droplets were taken by a microscopic method. Then, the particle size distribution was calculated and the following results were obtained. 1) The dispersing rate was formularized to first order of drop number as following equation.
