Abstract

The acidity and basicity of Sn−Mo−Ox catalysts with different Mo/Mo+Sn atomic ratios were measured by determining the adsorption isotherms of pyridine and acetic acid by chromatographic method. It was found that acidity and basicity go through a maximum at a Mo content of 15–20 at.%.

Abstract

Измеряли кислотность и основность катализаторов Sn−Mo−Ox с различным атомным соотношением Mo/Mo+Sn, определяя адсорбционные изотермы пиридина и уксусной кислоты хроматографическим методом. Кривые кислотностн и основности имеют максимум при содержании Mo=15–20 at.%.
