研制了一种用于电合成的陶瓷电化学反应器。CEM由五个结构化陶瓷层的组装构成。在一层上，丝网印刷了具有亚毫米电极间间隙的铂叉指带电极。微反应室由七个通道构成，其体积小于100微升。在850 ℃下烧结1小时后，CEM表现为固体和致密单元。将CEM直接连接到质谱仪的六端口阀，允许对反应混合物进行在线取样和分析。进行2-糠酸甲酯的甲氧基化，并通过质谱分析研究在CEM中停留时间的影响。
A ceramic electrochemical reactor (CEM) devoted to electrosyntheses was developed. The CEM was constituted by the assembly of five structured ceramic layers. On one layer, platinum interdigitated band electrodes with a submillimetre interelectrode gap were screen-printed. The microreactor chamber was constituted by seven channels and its volume was less than 100 microL. After a sintering step at 850 degree C for 1 h, the CEM appeared as a solid and compact unit. The CEM was directly connected to the six port valve of a mass spectrometer allowing an on-line sampling and analysis of the reaction mixture. The methoxylation of the methyl-2-furoate was carried out and the effect of the residence time in the CEM was investigated thanks to mass spectrometry analyses.
