Making of multifunctionalized mesostructured porous oxide, used for e.g. selective adsorption, comprises polycondensation, separation, reaction with a first agent, elimination, reaction with a second agent and recuperation

摘要

Preparation of multifunctionalized mesostructured porous oxide (I) comprises: polycondensating an oxide precursor (A) in an acid medium, in a micellar solution of ionic surface-active (A1); separating (A); reacting (A) with a first functionalized agent; eliminating (A1); reacting (A) with a second functionalized agent; repeating elimination and reaction of (A); optionally eliminating the remaining (A1); and recovering (I). Preparation of multifunctionalized mesostructured porous oxide (I) comprises: polycondensating an oxide precursor (A) in an acid medium, in a micellar solution of ionic surface-active (A1) (which leads by self-assembly to (I) containing surface-active micelle); separating (A) formed from the reactive mixture; reacting (A) containing (A1) with a first functionalized agent; eliminating at least partially (A1) of functionalized (A); reacting (A) with a second functionalized agent (where the first and second functionalized agents can form a covalent bond with the hydroxy groups released from (A)); repeating elimination and reaction of (A) with functionalized second agent for each additional functionality with a functionalized agent; optionally eliminating the remaining (A1); and recovering (I). An INDEPENDENT CLAIM is also included for (I) obtained by the process.
