Title:
NANOPOROUS DETECTORS OF MONOCYCLIC AROMATIC COMPOUNDS AND OTHER POLLUTANTS
Document Type and Number:
WIPO Patent Application WO/2010/004225
Kind Code:
A3
Abstract:
Porous sol-gel material essentially consisting of units of one or more first polyalkoxysilanes chosen from the following compounds: (chloromethyl)triethoxysilane; 1,3-dimethyltetramethoxydisiloxane; ethyltrimethoxysilane; triethoxy(ethyl)silane; triethoxymethylsilane; triethoxy(vinyl)silane; trimethoxymethylsilane; trimethoxy(vinyl)silane; tetraethoxysilane or tetramethoxysilane (TMOS) and of units of one or more second polyalkoxysilanes chosen from the following compounds: (N‑(3-(trimethoxysilyl)propyl)ethylenediamine; 3‑aminopropyltriethoxysilane (APTES) and 3-aminopropyltrimethoxysilane, in a first polyalkoxysilane/second polyalkoxysilane molar ratio of 1/0.01 to 1/1, optionally comprising a probe molecule, method of preparation and applications in the trapping of monocyclic aromatic hydrocarbons and other pollutants or in their detection.
