一般描述

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。它参与金/木炭或金/石墨催化的甘油氧化反应。参与无溶剂条件下的羟醛缩合反应。

应用

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′-双(磺酸基)-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转化为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。
  • ZSM(zeolite socony mobil)沸石的合成。


氢氧化钠可用于胶体二氧化硅比表面积的滴定法测定。它可用于硼氢化钠的直接氧化，通过循环和线性伏安法、计时电流法和计时电位法开展研究。可用于制备柠檬酸缓冲液和硼酸缓冲液。

它可用于合成：
  • 烷基芳基氨基磺基甜菜碱
  • (3 -[4-叔辛基苯氧基乙氧基乙氧基乙基]二甲基氨丙烷磺酸酯(XOSB)
  • 三磺基甜菜碱(TriSBn)


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。

特点和优势

  • 提高效率——免除需要松散硬化粉末的时间和精力
  • 更加安全——避免使用工具大力敲碎团块的风险
  • 更加经济——制备和溶剂化速度更快，提高效率并节约成本
  • 质量保证——经过专业检测的出色品质，无抗结剂添加
  • 灵活的用量选择——有从研究到放大级别的用量规格可供选择
