摘要

本研究使用巴基斯坦斯瓦特地区的本地石灰石合成丙酸钙。让粉末状石灰石与丙酸反应,研究合成参数的影响,即粒度(50、100、150 和 200 目)、丙酸(10、15 和 30%)、固液比(0.1:10、0.12:1、0.14:1 和 0.16:1)、反应时间(1、1.5、2 和 2.5 小时)和温度(60、80、90 和 100 °C)对丙酸钙收率和纯度的影响进行了研究。结果表明,最佳合成参数为粒度 200 目、丙酸浓度 15%、固液比 0.14:1、反应时间 2.5 小时和温度 80 ℃。在最佳条件下得到的产物通过红外光谱、热重仪和扫描电子显微镜进行了表征。结果表明,该工艺可获得纯度≥ 99.8%、收率 85% 的产品。

Synthesis of calcium propionate from indigenous limestone from Swat area in Pakistan
In this study, native limestone from the Swat area of Pakistan was used for the synthesis of calcium propionate. The powdered limestone was allowed to react with propionic acid and the effect of the synthesis parameters, that is, the particle size (50, 100, 150, and 200 mesh), propionic acid (10, 15, and 30 %), solid-liquid ratio (0.1:10, 0.12:1, 0.14:1, and 0.16:1), reaction time (1, 1.5, 2, and 2.5 hours) and the temperature (60, 80, 90, and 100 °C) on the percentage yield and purity of calcium propionate was studied. The results showed that the optimum synthesis parameters were 200 mesh particle size, 15% propionic acid concentration, 0.14:1 solid-liquid ratio, 2.5 hours reaction time, and 80 °C temperature. The product obtained under optimal conditions was characterized by infrared spectroscopy, thermogravimetry, and scanning electron microscopy. The results revealed that a product having ≥ 99.8% purity with 85% yield can be obtained by this process.
