对与甘氨酸,丙氨酸或β-丙氨酸有关的环状氨基取代的羧酸的九种甲酯进行电化学氟化。这样以合理的产率得到了相应的全氟氟化物和裂解产物。作为环状氨基取代基,研究了吡咯烷基,吗啉代,哌啶子基,六亚甲基亚氨基和N'-甲基哌嗪基。未观察到环化副产物的形成,这与脂族二烷基氨基取代的羧酸的氟化形成对比。从这样的2-环氨基丙酸甲酯[环氨基:吡咯烷基,吗啉代或哌啶子基],与全氟酸氟化物一起得到全氟甲基酯,产率为1-2%和14-29。 % 分别。前一种化合物的形成归因于庞大的环状氨基的阻断作用。报告了所获得的新化合物的物理性质及其光谱(19 F NMR,质量和IR)数据。

The filter medium is a filter medium which uses a liquid containing oil and water as a separation target, and has a channel for the liquid. The filter medium includes a base constituting the channel, and one or more of nitrogen-containing fluorine compounds which are provided on at least a portion of a surface of the channel. The nitrogen-containing fluorine compound includes an oil-repellency imparting group and any one hydrophilicity imparting group selected from a group consisting of an anion type, a cation type, and an amphoteric type, in a molecule.
