4,6-二羟基嘧啶废水中提取甲酸钠的研究

Study on extraction of sodium formate from 4,6-dihydroxypyrimidine wastewater

研究了一种从4,6-二羟基嘧啶废水中提取甲酸钠的方法。4,6-二羟基嘧啶废水经过浓缩除氯化钠盐,得到富含甲酸钠母液,富含甲酸钠母液经冷冻得到二水甲酸钠,二水甲酸钠重结晶得到纯度为97%以上的甲酸钠。采用该方法实现了甲酸钠和氯化钠的分离。

A method for extracting sodium formate from wastewater was studied.The wastewater was concentrated and desalted to obtain mother liquor rich in sodium formate,which was then frozen to obtain sodium formate dihydrate,and the sodium formate dihydrate was recrystallized to obtain sodium formate with a purity of more than 97%,thus separating sodium formate from sodium chloride.
