The structure and physicochemical properties of polyacrylamide (PAA), which is formed in the sulfur dioxide–acrylamide–water reaction system, depend on the synthesis temperature. It has been shown that the addition of ...

The present research has studied the spectral data, thermochemical transformations and hydrolysis of hexafluorosilicates with guanidine containing cations (C22H32Cl2N10)SіF6 (І) and (C21H45N9)(SiF6)1.5 (ІІ) for their ...

The reaction products formed in the SO2–L–H2O–O2 systems (L is n-propylamine, n-butylamine, tert-butylamine, n-heptylamine, n-octylamine, aniline) were isolated and identified as “onium” salts [n-C3H7NH3]2SO4, [n-C4H9NH3]2SO4, ...

The degree of hydrolysis α is within 89.0–99.8%, approaching to quantitative values in some cases. The closeness of the values α agrees with the determination of the pH of aqueous solutions of salts which were in a narrow ...

There was shown that the water solubility of hexafluorosilicates with aromatic “onium” cations — protonated forms of pharmaceuticals inverse-proportionally correlates with the number of short interionic contacts (H-bonds), ...

In our previous work, it was shown that the newly synthesized "onium" hexafluorosilicate has caries preventive effect significantly higher than a similar action of sodium fluoride. This study determined caries-preventive ...
