　　無水醋酸鈉想要達到一定的使用效果，是需要我們對其進行水溶液制備的，在水溶液制備的時候要注意對制備過程的嚴格把控，制備的過程需要用到一些化學物品，在選擇原料的時候注意純度的把控，下面我們就來了解下水溶液的制備過程。 </p> <p> <br /> </p> <p align="center"> <img title="無水醋酸鈉" alt="無水醋酸鈉" src="/Upload/thumb_5b447567d24c2_bateditor.jpg" width="400" height="300" /> </p> <p> 　　1、由醋酸鈣與純堿進行復分解反應，變為無水醋酸鈉；<br /> 　　2、將反應液濃縮至26°加活性炭脫色，然后進行冷卻結晶，離心分離即得成品；<br /> 　　3、當需獲得無水醋酸鈉時，將結晶再重新熔化，真空吸濾；<br /> 　　4、將母液結晶放在不銹鋼槽中冷卻，然后再離心、吸濾、甩干后，用電加熱法使晶體脫水，干燥，即得無水品。也可用醋酸和苛性鈉直接反應生成無水醋酸鈉水溶液。<br /> 　　以上就是對無水醋酸鈉水溶液制備的情況介紹，在整個制備過程中要注意方法的正確掌握，要注意把反應溫度控制在一個合理的區間范圍內，做好脫水以及干燥的處理，確保制得的水溶液是符合生產要求的。 </p></div> <div
