| Abstract: | In this paper,the preparation method of calcium propionate,which is feed mildew inhibitor with high efficiency,was summarized. We found out the optimal technology conditions of calcium propionate made from eggshells with neutralization were as follows:the reaction temperature was 50 ℃,the propionate was over much 50%,the time of reaction were 45 minutes. After filtering,concentrating and drying,we can get substance of calcium propionate. This technologic process made product,whose percentage reached over 90%. |
