Aa. Plakidkin et al., ACIDIC CENTERS ON THE SURFACE OF SILVER CATALYST FOR FORMALDEHYDE PREPARATION AND WAYS OF ITS REGENERATION, Russian journal of applied chemistry, 70(9), 1997, pp. 1419-1422
The concentration of acid centers on the surface of catalysts subjecte
d to various treatments was measured by nonaqueous potentiometric titr
ation. The influence is considered of the acidity of the catalyst surf
ace on the main process, methanol oxidation into formaldehyde, and on
the side process, formation of condensation products.
