Abstract:
(EN) A methylsilicic acid hydrogel is produced by reacting a solution of sodium methyl siliconate with a gaseous acid agent. The resulting product is vacuumised to remove residual gas, and washed with water. A significant OH-group content in the hydrogel, which results from bubbling the gaseous acid agent through the solution of sodium methyl siliconate, makes it possible to increase the selectivity of the adsorption properties when the hydrogel is used in medicine and veterinary science.
(FR) L’hydrogel d’acide méthylsilicique est obtenu par l’interaction d'une solution de siliconate de méthyle de sodium avec un agent acide gazeux. Le produit obtenu est mis sous vide pour éliminer le gaz résiduel puis rincé à l’eau. Une teneur importante de l’hydrogel en groupes OH due à un barbotage de l'agent acide gazeux par le mélange de siliconate de méthyle de sodium assure une plus grande sélectivité des propriétés d'adsorption lors de son utilisation en médecine et dans le domaine vétérinaire-
(RU) Гидрогель метилкремниевой кислоты получают взаимодействием раствора метилсиликоната натрия с газообразным кислым агентом. Полученный продукт вакуумируют для удаления остаточного газа и отмывают водой. Значительное содержание ОН-групп в гидрогеле, обусловленное барботированием газообразного кислого агента через раствор метитлсиликоната натрия, обеспечивает повышенную селективность адсорбционных свойств при его использовании в медицине и ветеринарии.
