performed in a solid–liquid phase-transfercatalysis (SL–PTC) system using sodium hydroxide as the solid phase. Various parameters that influenced the pseudo-first-order rate constant including stirring speed, catalysts, salt, water and temperature were investigated to explore the process of the generation and transfer of the active intermediate. A reasonable interfacial mechanism of the PTC reaction of
