将3-二烷基氨基取代的丙酸的六种甲酯进行电化学氟化,得到相应的全氟代氟化物。研究了以下二烷基氨基取代基:二乙基氨基,二正丙基氨基,二正丁基氨基,吡咯烷基,吗啉代和哌啶子基。这些以合理收率获得的全氟酸氟化物被认为是制备软质(可降解)含氟化合物的潜在关键前体。这些盐在水溶液中显示出明显降低的表面张力。报告了所获得的所有全氟酸氟化物的物理性质,以及它们的光谱数据(19 F NMR,质谱和IR光谱)。
A process for removing contaminants from the surface of a substrate comprises contacting the substrate with a cleaning composition comprising at least one mono-, di-, or trialkoxy-substituted perfluoroalkane, perfluorocycloalkane, perfluorocycloalkyl-containing perfluoroalkane, or perfluorocycloalkylene-containing perfluoroalkane compound, the compound optionally containing additional catenary heteroatoms. The compounds exhibit good solvency properties while being environmentally acceptable.
