以贝壳为钙源一次煅烧法制取柠檬酸钙

Study on the preparation of the calcium citrate from shells with once time calcination

本论文采用一次煅烧法,研究了以贝壳为钙源制备柠檬酸钙的工艺条件。通过综合利用单因素实验、正交实验对影响反应的各因素进行分析,得出制备柠檬酸钙的最佳条件是:1g煅烧后的贝壳粉加10mL水,用2mol/L的柠檬酸15mL在70℃条件下中和反应,制得柠檬酸钙的产率为73.36%,纯度为93.8%。

In this paper, experiments were conducted to study the preparation of the calcium lactate from shells with calcination only once. The optimal condition, which was obtained by single factor experiments and orthogonal experiments, includes l g egg powder, 10 mL water, 2mol/L lactate acid 15 mL, reaction temperature 60℃, with a yield of 73.36% and a purity of 93.8%.
