摘要
本项目在原生产工艺的基础上作了较大的改进,即采用一步法在无有机溶剂(原溶剂为乙醇)的条件下合成双乙酸钠。以碳酸钠和乙酸为原料在水系介质中进行反应。实验结果证明:用水替代乙醇作溶剂,在调整后的工艺条件下,所制备的双乙酸钠产品质量稳定,收率高,生产成本低,设备投资少的特点。
Traditional process technology was innovated in this paper. SDA was synthesized from sodium carbonate and acetic acid as raw materials in water - medium instead of ethanol. The test results showed that the new process had the advantages of stable quality,high yield,low cost and less equipment investment.
