一般說明

氢氧化钠(NaOH)又称苛性碱,是一种水溶性无机碱,具有广泛的工业应用,如滴定、溶出度测定以及去除吸气瓶中的酸性气体等。它参与由金/木炭或金/石墨催化的甘油氧化。它参与无溶剂醛缩合反应。

應用

氢氧化钠可用作滴定法、溶出度测定的碱,调节pH值和去除吸气瓶中的酸性气体。
它可用于以下过程:
  • 在存在金催化剂的情况下将甘油转化为甘油酸。
  • 钯催化乙烯基烷氧基硅烷与芳基溴或氯化物的交叉偶联反应,以生成苯乙烯。
氢氧化钠(NaOH)应用于以下过程:
  • 制备用于蛋白质交联技术的3,3′-二(磺胺)-4,4′-二(氯乙酰氨基)偶氮苯钠(BSBCA)
  • 制备电解液,以研究电解液组成对电化学还原法将CO2化为CO的影响。
  • 制备用于保存睾丸生殖细胞三维染色质结构的三维(3D)载玻片法的CSK(细胞骨架)缓冲液。
  • ZSMs (zeolite socony mobils)的合成。
氢氧化钠,可用滴定法测定胶体二氧化硅的比表面积。它还可用于硼氢化钠的直接氧化,可用循环伏安法、线性伏安法、计时安培法和计时电位法检测。可用于制备柠檬酸缓冲液和硼酸缓冲液。它可用于合成:
  • 烷基芳基氨基磺酸盐
  • (3 -[4-辛基苯氧基乙氧基乙氧基]二甲基氨基丙烷磺酸盐(XOSB)
  • 三磺甜菜碱(TriSBn)
