摘要
The Lewis acid-catalyzed addition of tri-methylsilyl cyanide to p-chlorobenzaldehyde in a micro-channel reactor was investigated.The microchannel was integrated to promote both reaction and separation of the biphase system.FeF3 and Cu(triflate)2 were used as water-stable Lewis acid catalysts.Sodium dodecyl sulfate was incorporated in the organic-aqueous system to enhance the reactivity and to manipulate the multiphaseflow inside the microchannel.It was found that the dynamics and the kinetics of the multiphase reaction were affected by the new micellar system.Parallel multiphaseflow inside the microchannel was obtained,allowing for continuous and acceptable phase separation.Enhanced selectivity was achieved by operating at lower conversion values.
