  • This study focuses on changes of pH value of water after adding ten kinds of natural minerals, and composition changes of natural minerals after dipping water of partial acidity or partial alkalescency.At the same time, the effect of ten type natural minerals and their dif ferent pH values on hydrolyzed catalysis on fatty acid has also been studied.The hydrolysis rates of fatty acid ester have been obtained by the presence of ten kinds of natural minerals.Our results show that different minerals will bring changes of pH value of paritial acidity or partial alkalescency, but the mineral components have not changed after dipping water of partial acidity or partial alkalescency. Many minerals except for dolomite and Ca-montmorillonite in the partial alkalescency are relatively favorable for hydrolysis of fatty acid ester at low temperature.The hydrolysis rates of fatty acid ester catalyzed by minerals at low temperature are ranging from 90% to 50%,mostly in 22%～ 34%.

Abstract: This study focuses on changes of pH value of water after adding ten kinds of natural minerals, and composition changes of natural minerals after dipping water of partial acidity or partial alkalescency.At the same time, the effect of ten type natural minerals and their dif ferent pH values on hydrolyzed catalysis on fatty acid has also been studied.The hydrolysis rates of fatty acid ester have been obtained by the presence of ten kinds of natural minerals.Our results show that different minerals will bring changes of pH value of paritial acidity or partial alkalescency, but the mineral components have not changed after dipping water of partial acidity or partial alkalescency. Many minerals except for dolomite and Ca-montmorillonite in the partial alkalescency are relatively favorable for hydrolysis of fatty acid ester at low temperature.The hydrolysis rates of fatty acid ester catalyzed by minerals at low temperature are ranging from 90% to 50%,mostly in 22%～ 34%.
