Sol-gel material absorbing aldehydes and ketones, and the process for its preparation

Abstract

The present invention concerns an adsorbent porous sol-gel material comprising at least-silane oxides;—an inorganic and/or organic acid with a boiling temperature higher than 100° C.;—a molecular probe of general formula (I) or one of the salts of same in which R1, R2, R3, R4, R5, R6 separately represent a hydrogen atom, a (C1-C6) alkyl group, a (C3-C7) cycloalkyl group, an alkyl-(C3-C7) cycloalkyl group; in which Z represents a spacer group chosen from a (C1-C16) alkyl group, a (C2-C16) alkenyl group, a (C2-C16) alkynyl group, a (C1-C16) halogenoalkyl group, an aryl group, an aryloxy group, a carbocycle group, or an aryl-(C1-C16) alkyl group.
