Influence of Dispersion Medium on Clusterization of Water and Hydrogen Peroxide Bound To Silica-Sorbitol Composite
Keywords:
A-300/sorbitol composite, NMR spectroscopy, state of water, hydrogen peroxide, effect of solventsAbstract
The interfacial behavior of water and hydrogen peroxide in solution alone or adsorbed on a surface of nanosilica A-400, silica gel Si-60 or composite prepared using mechanochemical activation of sorbitol – nanosilica A-300 has been studied by low-temperature 1H NMR spectroscopy. It has been shown that water in the hydrogen peroxide solution forms clusters of average radius R » 1 nm. At a surface of nanosilica, water forms clusters at R < 0.8 nm and domains at R = 2–50 nm. For the solution bound to the A-300/sorbitol composite, two main signals appear in the spectra at the chemical shift of 4 and 6 ppm corresponding to structures of strongly associated water dissolved different amounts of H2O2. In this case, the formation of domains is preferable at R » 50 nm. Addition of polar solvents (CD3CN, DMSO) leads to the formation of clusters including H2O – electron-donor complexes.References
