摘要: 本文利用二次反应法制取优质防霉剂丙酸钙((C3H5O2)2Ca),在单因素试验的基础上,再采用二次回归正交旋转组合试验设计得出了丙酸与蛋壳粉反应的回归方程,经方差分析检验显示此模型是极显著的.确定了鸡蛋壳制备(C3H5O2)2Ca的最佳工艺条件为:反应温度77.7℃,料液比为1:17.4,一次反应时间为1.8h,二次反应时间为55.8min,丙酸用量为理论用量的159.7%,在此条件下,蛋壳制取(C3H5O2)2Ca的得率为98.26%,纯度为96.52%,其它指标均符合HG2921-1999丙酸钙行业标准.

Abstract: The preparation of calcium propionate by second conversion using recycled eggshell was studied in this paper.On the basis of single-factor test,regression equation was established by orthogonal rotating combinatorial design of four factors and five levels.The result of variance analysis showed that there exist significant difference in the model.According to this model,the optimal reaction conditions are as follows:reaction temperature 77.7℃,the liquid ratio 1:17.4,the amount of propionate 159.7%,the first reaction time 1.8 h,second conversion time 55.8min.Under these conditions,the yield of calcium propionate was 98.26%.the purity reached 96.52%.All other parameters conformed to the HG2921-1999 industrial standard.
