氫氧(yang)化(hua)(hua)鈉(na)用(yong)(yong)(yong)途極廣(guang)(guang)。用(yong)(yong)(yong)于制(zhi)造(zao)紙漿、肥皂、染(ran)料、人(ren)造(zao)絲、制(zhi)鋁(lv)、制(zhi)、棉織(zhi)品整理、煤焦(jiao)油產物的(de)提純，以及食品加(jia)工(gong)、木(mu)材加(jia)工(gong)及機(ji)械(xie)工(gong)業(ye)(ye)等(deng)方面(mian)。氫氧(yang)化(hua)(hua)鈉(na)使用(yong)(yong)(yong)相當(dang)廣(guang)(guang)泛，除了在化(hua)(hua)學實驗中被用(yong)(yong)(yong)做試(shi)劑以外，還可用(yong)(yong)(yong)做堿(jian)性(xing)干燥(zao)劑，這是(shi)由于它具有(you)很強(qiang)的(de)解潮性(xing)。氫氧(yang)化(hua)(hua)鈉(na)廣(guang)(guang)泛運用(yong)(yong)(yong)于國民經濟，很多工(gong)業(ye)(ye)部門(men)生產都會使用(yong)(yong)(yong)氫氧(yang)化(hua)(hua)鈉(na)。扔掉(diao)的(de)氫氧(yang)化(hua)(hua)鈉(na)不能(neng)直接倒入下(xia)水(shui)道，可以運用(yong)(yong)(yong)酸性(xing)中和，如鹽酸、硫酸等(deng)。氫氧(yang)化(hua)(hua)鈉(na)仍是(shi)許多有(you)機(ji)反應的(de)出色催化(hua)(hua)劑。

扔掉的氫(qing)氧(yang)化鈉(na)不(bu)能直(zhi)接倒入下(xia)水(shui)道，可(ke)以(yi)運用(yong)酸(suan)性中和，如(ru)鹽酸(suan)、硫酸(suan)等。氫(qing)氧(yang)化鈉(na)仍是許多有機反應的出色催化劑。氫(qing)氧(yang)化鈉(na)被使用(yong)在水(shui)處理方(fang)面的如(ru)下(xia)課題：消除水(shui)的硬度；調節水(shui)的pH值；對(dui)廢水(shui)進行中和；離(li)子交換樹(shu)脂(zhi)的再(zai)生(sheng)；通過沉淀消除水(shui)中重(zhong)金屬離(li)子。固體氫(qing)氧(yang)化鈉(na)可(ke)裝(zhuang)入0.5毫米厚的鋼(gang)桶中嚴封，每(mei)桶凈重(zhong)不(bu)超過100 公斤；塑料袋或二層牛皮(pi)紙袋外(wai)全開(kai)口或中開(kai)口鋼(gang)桶。
