摘要
以花蛤壳为原料,采用水热法制备了丙酸钙.在单因素的基础上,研究了液固比、酸壳比、反应时间和反应温度对丙酸钙产率的影响,并通过四因素三水平的响应面试验对制备工艺进行优化.结果表明,最佳的制备工艺为液固比21 mL/g、酸壳比1. 85 mL/g、反应时间184 min和反应温度76℃,在此条件下,丙酸钙产率为96. 15%,与预测值相对误差为0. 56%,说明该回归方程具有较高的准确性与可行性,可用于丙酸钙水热法制备工艺的优化.
Calcium propionate was prepared by hydrothermal method using clam shells as raw material. On the basis of single factor, the effects of liquid-solid ratio, acid-shell ratio, reaction time and temperature on the yield of calcium propionate were studied, and the preparation process was optimized by a four-factor and three-level response surface e xperiment. The results showed that the best preparation process was liquid-solid ratio 21 mL/g, acid-shell ratio 1. 85 mL/g,reaction time 184 min and temperature 76 °C. Under the condition, the yield of calcium propionate was 96. 15%. The relative error was 0. 56% compare to the predicted value, which indicated that the regression equation had high accuracy and feasibility and can be used for the optimization of the hydrothermal preparation process of calcium propionate.
