    • A sodium sensor to measure a concentration of sodium methylate in methanol. The sensor assembly includes a solid alkali ion conducting membrane, a reference electrode, and a measurement electrode. The solid alkali ion conducting membrane transports ions between two alkali-containing solutions, including an aqueous solution and a non-aqueous solution. The reference electrode is at least partially within an alkali halide solution of a known alkali concentration on a first side of the solid alkali ion conducting membrane. The measurement electrode is on a second side of the solid alkali ion conducting membrane. The measurement electrode exhibits a measurable electrical characteristic corresponding to a measured alkali concentration within the non-aqueous solution, to which the measurement electrode is exposed.
    • 用于测量甲醇钠甲醇浓度的钠传感器。 传感器组件包括固体碱离子传导膜,参比电极和测量电极。 固体碱离子导电膜在两种含碱溶液之间输送离子,包括水溶液和非水溶液。 参考电极至少部分地在固体碱离子传导膜的第一侧上已知碱浓度的碱金属卤化物溶液中。 测量电极位于固体碱离子传导膜的第二侧。 测量电极显示对应于测量电极暴露于其中的非水溶液内测量的碱浓度的可测量的电特性。

    • A method for producing an alkali metal hydroxide, comprises providing an electrolytic cell that includes at least one membrane having ceramic material configured to selectively transport alkali metal ions. The method includes introducing a first solution comprising an alkali metal hydroxide solution into a catholyte compartment such that said first solution is in communication with the membrane and a cathode. A second solution comprising at least one alkali metal salt and one or more monovalent, divalent, or multivalent metal salts is introduced into an anolyte compartment such that said second solution is in communication with the membrane and an anode. The method includes applying an electric potential to the electrolytic cell such that alkali metal ions pass through the membrane and are available to undertake a chemical reaction with hydroxyl ions in the catholyte compartment to form alkali metal hydroxide.
    • 一种碱金属氢氧化物的制造方法,其特征在于,提供一种电解槽,该电解槽具有至少一层具有选择性地输送碱金属离子的陶瓷材料的膜。 该方法包括将包含碱金属氢氧化物溶液的第一溶液引入阴极电解液室,使得所述第一溶液与膜和阴极连通。 将包含至少一种碱金属盐和一种或多种一价,二价或多价金属盐的第二溶液引入阳极电解液室,使得所述第二溶液与膜和阳极连通。 该方法包括向电解槽施加电位使得碱金属离子通过膜并且可用于与阴极电解液室中的羟基离子进行化学反应以形成碱金属氢氧化物。
