摘要
以鸡蛋壳为钙源制备乳酸-葡萄糖酸钙(CLG),并考察了鸡蛋壳的煅烧条件、原料配比、反应时间、反应温度及加水量等因素对乳酸-葡萄糖酸钙产量及溶解度的影响。实验结果表明,鸡蛋壳的最佳煅烧温度1000℃、煅烧时间1h;蛋壳灰分4g、0.095mol乳酸、0.048mol的葡萄糖酸、加水量70mL、温度为50℃、反应时间1h为最佳工艺条件,其产品产率高达94%以上、常温下溶解度高达21%以上。
The paper reports the result of using egg shells as calcium source to produce calcium lactate gluconate （CLG）.The fluence on yield and dissolution degree from incineration condition of egg shells, proportion of materials, concentration of reactant, time of reaction and temperature of reaction are discussed, The experimental results show that the incinerating condition for egg shells are optimal at 1000℃ for lh,and calcium lactate gluconate can be prepared at 50℃ for lh with other conditions of egg shells ash of 4g,lactic acid of 0.095mol,gluconic acid of 0.048mol and water of 70mL, and the gluconate is more than degree is more than 21% yield of calcium lactate 94% ,and dissolution at room temperature.
