过去在研究相转移催化反应机理时仅考虑在相转移催化剂作用下反应物、中间体(离子)、产物在两相间的转移,并导致两相间反应进行。我们以研究结果证明水相的表面能和两相的界面能与相转移催化反应的结果有密切关系。

关键词: 相转移催化, 界面能, 表面活性剂, 氟化合物

The interface tension and surface tension of the phase transfer catalysis reactions (using phase transfer catalysts, hydrocarbon surfactants and fluorocarbon surfactants) have been determined. It is found that phase transfer catalysts and surfactants can reduce the interface tension and surface tension of the reaction systems. The results show that the interface tension and surface tension play an important role in the reaction systems.

Key words: PHASE TRANSFER CATALYSIS, INTERFACIAL ENERGY, SURFACTANTS, FLUORINE COMPOUNDS
