Multiphase surfactant-assisted reaction-separation system in a microchannel reactor

Salah ALJBOUR, Tomohiko TAGAWA, Mohammad MATOUQ, Hiroshi YAMADA

Frontiers of Chemical Science and Engineering 2009, Volume 3, Issue 1,   Pages 33-38 doi: 10.1007/s11705-009-0108-6

Abstract: The Lewis acid-catalyzed addition of trimethylsilyl cyanide to -chlorobenzaldehyde in a microchannel reactor was investigated. The microchannel was integrated to promote both reaction and separation of the biphase system. FeF and Cu(triflate) 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 multiphase flow inside the microchannel. It was found that the dynamics and the kinetics of the multiphase reaction were affected by the new micellar system. Parallel multiphase flow inside the microchannel was obtained, allowing for continuous and acceptable phase separation. Enhanced selectivity was achieved by operating at lower conversion values.
