该文利用鸡蛋壳制取乳酸钙.采用直接中和法,将经过预处理的蛋壳粉碎至一定细度,加入乳酸进行中和反应制取乳酸钙.试验过程中对直接中和反应过程中各影响因素进行了研究探讨,筛选出最佳中和反应条件.并采用了三元线性回归正交试验对试验结果进行了显著性分析.试验结果表明,加入蛋壳粉10 g、乳酸18.5 mL、蒸馏水100mL,,在中和反应温度35℃、反应时间2 h的条件下,制取乳酸钙的产率可达79.23%,质量分数达到86.93%.通过这种方法制取乳酸钙,既充分挖掘了鸡蛋壳中潜在的利用价值,又解决了蛋壳造成的环境污染问题.

In this paper, calcium lactate was made from eggshell. The eggshell was properly shattered, the lactate was added in to react with eggshell to prepare calcium lactate by direct reaction. The factors in the reaction were studied, and the optimal reaction condition was obtained. The results of regression-orthogonal combination experiment were analyzed by significance analysis. The results showed that the optimum conditions were: adding eggshell powder 10 g, lactic acid 18.5 mL, distilled water 100 mL, and the reaction temperature 35°C, reaction ...
