【摘要】:以雞蛋殼為原料,對真空微波輔助法制備醋酸鈣的加工工藝進行了優(yōu)化。以醋酸鈣產率為指標,考察了反應時間、固液比、微波功率、微波時間與真空度等醋酸鈣制備工藝技術參數。結果表明,在真空度0.06 MPa、微波功率500 W、微波時間1.5 min、固液比1∶5 g/mL,反應時間2 h時,醋酸鈣的產率達到最大值94.1%。此工藝制備醋酸鈣時間短、成本低、操作簡單,為醋酸鈣的工業(yè)化生產提供理論基礎。
[Abstract]:The preparation process of calcium acetate by vacuum microwave assisted method was optimized by using egg shell as raw material.Taking the yield of calcium acetate as an index, the technological parameters of preparation of calcium acetate were investigated, such as reaction time, solid-liquid ratio, microwave power, microwave time and vacuum degree.The results show that under the conditions of vacuum 0.06 MPA, microwave power 500 W, microwave time 1.5 min, solid-liquid ratio 1:5 g / mL, reaction time 2 h, the yield of calcium acetate reaches the maximum value of 94.1g / mL.The preparation of calcium acetate by this process has the advantages of short time, low cost and simple operation, which provides a theoretical basis for the industrial production of calcium acetate.
