Effect of Reaction Temperature on the Neutralization Rate of Fatty Acid in a Coagulation Particle Made by the Seed Coagulation Method from Polymer Latex

Abstract

This study focuses on the effect of reaction temperature in the range from 343 to 368K on the neutralization rate of fatty acid in a coagulation particle made by the seed coagulation method from polymer latex.
It was confirmed that, as reported in the previous paper, the unreacted coremodel can be applied at 343363K.
The diffusion coefficient of calcium hydroxide in the ash layer has a maximum value at about 363K.
This means that the diffusion of calcium hydroxide in the particle was hindered above 363K. This was thought to result from a decrease in porosity and pore diameter of the coagulation particle due to shrinkage of the coagulation particle by heat treatment.
