Abstract- The Pbotocheaical reactions of several famiZias of ketones adsorbed on various forms of silica hava been investigated. The influence of surface coverage, silica average Pore diameter, teqmrature, applied magnetic fields, and additives on the product distributions have been determined. tie results are consistent with a model in which the silica surface consists of two major regions, one consisting of stronger binding sites {active ailan groupsf and the other consisting of weaker binding sites ffrae sf~anol groups). The relative proportions of these two typBs of sites are relateii to the Pore size of the silica, smaller pores correla-ting with a larger fraction of the stronger binding sites and larger Pores correlating with a smalle...
