28 - 048MCM-41–Quaternary Organic Tetraalkylammonium HydroxideComposites as Strong and Stable Broensted Base Catalysts. —Quaternary tetraalkylammonium hydroxide grafted on MCM-41 is a strongBroensted catalyst for Knoevenagel condensations, Michael additions, and aldolcondensations. The mechanical stability of the inorganic support materialensures easy separation of the solid catalyst together with waste minimizationand the possibility of recycling. — (RODRIGUEZ, ISABEL; IBORRA, SARA;CORMA, AVELINO; REY, FERNANDO; JORDA, JOSE L.; Chem.
