常规方法:用内衬塑料袋，外套编织袋或麻袋包装。醋酸钠具有潮解法，贮运中要注意防潮，严禁与腐蚀性气接触，防止曝晒和雨淋，运输要加防雨覆盖物。
有吸湿性。易溶于水，溶于乙醇。低毒，半数致死量(大鼠，经口)3530mg/kg。
毒性分级:中毒
Acros Organics:乙酸钠 Acetic acid, sodium salt, anhydrous, for anal
方法一:由醋酸钙与纯碱进行复分解反应，变为醋酸钠，将反应液浓缩至26°Be，加活性炭脱色，然后进行冷却结晶，离心分离即得成品。当需获得无水醋酸钠时，将结晶醋酸钠再重新熔化，真空吸滤，将母液结晶放在不锈钢槽中冷却，然后再离心、吸滤、甩干后，用电加热法使晶体脱水，干燥，即得无水品。也可用醋酸和苛性钠直接反应生成醋酸钠。
