    摘要: The present invention relates to a method of preparing N-substituted maleimide in high purity and high yield, wherein, unlike a conventional method of preparing N-substituted maleimide after preparing N-substituted maleamic acid, an organic solvent, an acid catalyst, a dehydration co-catalyst and a stabilizer are added into a reactor without separately preparing N-substituted maleamic acid, and then a primary amine is added into the reactor to form an amine salt, maleic anhydride is added into the reactor, and the resulting mixture is subjected to a dehydration-cyclization reaction, wherein water produced during the reaction is azeotropically distilled with the organic solvent so as to effectively suppress formation of a maleimide polymer. Particularly, the invention simplifies the process, has high yield, minimizes side reactions, eliminates the introduction of expensive raw materials and the complicated treatment of the reaction solution and significantly shortens the time over which the raw materials and maleic anhydride are added.

    摘要: A serial interface interposed between two serially connected unit cells provides mechanical strength to the serial connection and conductive coupling therebetween. The serial interface includes an inter-connector having a first vent hole formed therein configured for conductively coupling an anode outer wall of a first unit cell and a cathode terminal of a second unit cell to each other; and a spacer having a second vent hole formed therein and configured to be disposed between the inter-connector and an anode outer wall of the second unit cell to prevent a short-circuit due to the movement of the inter-connector.
