FIELD: chemistry.
SUBSTANCE: invention relates to methods of producing modified silicagels. Method involves covalent immobilisation through a click-reaction of azido-alkyne cycloaddition of bromide of 5-(4-pro-2-ynyloxy)phenyl-2,3-diphenyl-2H-tetrazol-3-yl and 3-azidopropyl-silicagel. Process is carried out in a medium of acetonitrile in catalysis of 10 mol % copper (I) iodide and 100 mol % N,N,N',N'-tetramethylethylenediamine (TMEDA) with heating and stirring for 4 hours.
EFFECT: invention widens the range of silica-based sorbents with a covalently immobilized azole salt.
