摘　　要：针对目前国内工业上生产d-酒石酸方法的缺点,提出了以d-酒石酸钠为原料用电渗析生产d-酒石酸的方法.该法操作简单,技术可靠,得到的d-酒石酸产品质量分数99.5%以上,回收率95%,生产1t纯d-酒石酸晶体,电耗约2000kWh.对电渗析由d-酒石酸钠生产d-酒石酸方法与旧法作了简单的经济比较后认为,该法可用于工业生产.A new technological process of producing d-tararic aicd from its sodium salt solution by electrodialysis was proposed.The process has the advantages of simple operation and high yield.The purity of the product,d-tararic aicd,is over 99.5%,the content of sulfate anion in the product is less than 0.01%.The power consumption is about 2 000 kWh/t.
