Abstract
The article discusses the effect of various factors on the modification rate of polysilicic acid. The reaction of polysilicic acid with ethanolamine is due to the polycondensation of the silanol and hydroxyl groups. The formation of the corresponding product as a result of the reaction has been confirmed by IR spectroscopy. The dependence of the reaction rate on temperature and the addition of tetraethyl orthosilicate has been studied. The optimum time for modification was shown to be 5 hours without tetraethyl orthosilicate and a temperature of 60°C, and 2 hours and 60°C in the presence of tetraethyl orthosilicate.

Keywords
Silicic acid, Ethanolamine, Tetraethyl orthosilicate, Temperature, Reaction kinetics.
