Porous catalysis

WebThe preparation of a new class of reactive porous solids, prepared via straightforward salt metathesis reactions, is described here. Reaction of the dimethylammonium salt of a magnesium-based porous coordination cage with the chloride salt of [Cr II Cl(Me 4 cyclam)] + affords a porous solid with concomitant removal of dimethylammonium chloride. WebIn this study, a porous CaO-based catalyst was synthesized using a fast mineralization process induced by sodium poly (styrenesulfonate) (PSS) followed by calcination. The solid base catalyst was tested in palm oil transesterification to determine its viability in biodiesel production. Scanning electron microscopy ...
