THE EFFECT OF REVERSED MICELLAR SYSTEMS ON THE CATALYTIC ACTIVITY OF MONODISPERSE CATALYSTS - II - THE REACTION MODEL FOR STYRENE HYDROGENATION IN CTAB 1-HEXANOL (1-PENTANOL OR 1-BUTANOL) WATER REVERSED MICELLAR SOLUTION/

A general reaction model for styrene hydrogenation in the CTAB/1-hexan ol(1-pentanol or l-butanol)/water reversed micellar solutions was prop osed to interpret the catalytic behavior of monodisperse nickel boride particles prepared in situ. Based on this model, the effect of revers ed micellar components on hydrogenation activity of the catalyst has b een discussed in detail. It is worth noticing that, in the three rever sed micellar systems, adding ethanol into the reversed micellar soluti ons will result in the change of catalyst's activity in the different ways, i.e. decrease for the reversed micellar solution with the low CT AB concentration (6 wt%) and increase for those with the high CTAB con tent (23 wt % or 38 wt%). The result is attributed to the combined eff ects of the hydrogen transfer and the coagulation of the monodisperse catalysts on the activity of the catalyst.
