摘要
以废弃鸡蛋壳为原料用直接中和法制备丙酸钙。通过实验探究得出直接中和法制备丙酸钙的最佳物料比,最佳反应温度,最佳反应时间。反应温度为80℃,反应时间为4h,物料比为1∶2。此条件下丙酸钙产率达97.80%,纯度高达98.50%,符合国家食品级丙酸钙添加剂标准。
Calcium propionate was prepared from egg shells by direct neutralization method.The optimum material ratio,reaction temperature and reaction time of calcium propionate prepared by direct neutralization method were obtained through experimental investigation.When the calcium propionate yield was the highest,the reaction temperature was 80℃.The reaction time was 4h.The material ratio is 1∶2.Under these conditions,the yield of calcium propionate is up to 97.80%and the purity is as high as 98.50%,which conforms to the national food grade calcium propionate additive standard.
