    • An aryl-alkyl (R-Ar) hydrocarbon is prepared by an electrosynthesis process in an electrolytic cell (100) having an alkali ion conductive membrane (110) positioned between an anolyte compartment (112) configured with an anode (116) and a catholyte compartment (114) configured with a cathode (118). An anolyte solution (124) containing an alkali metal salt of an alkyl carboxylic acid (128) and an aryl compound (130) is introduced into the anolyte compartment (112). The aryl compound (130) may include an alkali metal salt of an aryl carboxylic acid, an arene (aromatic) hydrocarbon, or an aryl alkali metal adduct (Ar- M+). The anolyte solution (124) undergoes electrolytic decarboxylation to form an alkyl radical. The alkyl radical reacts with the aryl compound to produce the aryl-alkyl hydrocarbon.
    • 在具有位于阳极(116)的阳极电解液室(112)和阴极电解液(116)之间的碱金属离子传导膜(110)的电解槽(100)中,通过电合成工艺制备芳基 - 烷基(R-Ar) 隔室(114)配置有阴极(118)。 将含有烷基羧酸(128)和芳基化合物(130)的碱金属盐的阳极电解液(124)引入阳极电解液室(112)中。 芳基化合物(130)可以包括芳基羧酸的碱金属盐,芳烃(芳族)烃或芳基碱金属加合物(Ar-M +)。 阳极电解液(124)进行电解脱羧以形成烷基。 烷基与芳基化合物反应生成芳基 - 烷基烃。

    • Alkali bicarbonate is synthesized in an electrolytic cell (100) from alkali carbonate. The electrolytic cell (100) includes an alkali ion conductive membrane (110) positioned between an anolyte compartment (112) configured with an anode (116) and a catholyte compartment (114) configured with a cathode (118). The alkali conductive membrane (110) selectively transports alkali ions (120) and prevents the transport of anions produced in the catholyte compartment. An aqueous alkali carbonate solution is introduced into the anolyte compartment (112) and electrolyzed at the anode (116) to produce carbon dioxide and/or hydrogen ions which react with alkali carbonate to produce alkali bicarbonate. The alkali bicarbonate is recovered by filtration or other separation techniques. When the catholyte solution includes water, pure alkali hydroxide is produced. When the catholyte solution includes methanol, pure alkali methoxide is produced.
    • 在碱金属碳酸盐的电解池(100)中合成碱金属碳酸氢盐。 电解池(100)包括位于由阳极(116)构成的阳极电解液室(112)和配置有阴极(118)的阴极电解液室(114)之间的碱金属离子传导膜(110)。 碱性导电膜(110)选择性地输送碱离子(120)并防止在阴极电解液室中产生的阴离子的运输。 将碱金属碳酸盐水溶液引入阳极电解液室(112)中并在阳极(116)处电解以产生与碱金属碳酸盐反应产生碱式碳酸氢盐的二氧化碳和/或氢离子。 通过过滤或其他分离技术回收碱金属碳酸氢盐。 当阴极电解液包含水时,产生纯碱氢氧化物。 当阴极电解液包含甲醇时,产生纯碱金属甲醇盐。
