| Abstract: | During the solid-phase reaction process of sodium sorbate and sodium carbonate to produce sodium sorbate, here appeared that the temperature of reaction system jumped higher, reactants bounding which lead to the reaction uncontrollable and the addition of sodium carbonate more than chemical reaction needed. These results would affect practical reaction process and the quality of the resulting product. In our presented study, X-ray diffraction analysis, scanning electron microscopy analysis, differential the... |
