英文摘要: To control the catalytic activity and selectivity by regulating the Lewis acidity of catalyst is always the important field of research on catalytic alkylation reaction. Our research aims at synthesizing dodecylbenzene with benezene and twelve olefin. A series of bis[(perfluoroalkyl)sulfonyl]imides salt with different perfluoroalkyl-group and different metal cation will be designed and prepared. The research on the relationship of delocalization of negative charge of nitrogen atom in the bis[(perfluoroalkyl)sulfonyl]imides anion, metal cation and acidic strength will be investigated . The catalytic performance and catalytic mechanism will then be studied and the system of bis[(perfluoroalkyl)sulfonyl]imides salt catalysts used for synthesizing dodecylbenzene will be built and optimized, which will provide theoretical and technological basis for developing new catalysts on alkylation.
