“…After each recycling run no leaching of the H 3 PW could be detected by UV-Vis spectroscopy. In the case of H 3 PW on pristine silicalite-1, a significant decrease in conversion was observed under similar reaction conditions, indicating an improved H 3 PW-support interaction for silicalite-1 [92] Table 3. Specific surface area (S BET ), total pore volume (V total ) and total acidity by NH 3 -TPD of H 3 PW/SiO 2 solid acid catalysts.…”

“…In a similar approach, Preyssler‐type HPAs were incorporated into mesoporous SiO 2 materials and applied in the esterification of HMF with n BuOH [92] . Although commercially available Keggin‐HPAs are most commonly used, Preyssler‐HPAs exhibit beneficial properties such as an increased acidity and hydrolytic stability [93–95] .…”

“…Este comportamiento se puede relacionar con una mayor cantidad de sitios activos que son necesarios para la transformación del intermediario de Knoevenagel, que conduce a la formación del uracilo, por lo tanto, una masa de catalizador <50 mg no es suficiente para logar esta transformación con altos rendimientos. El comportamiento directamente proporcional entre la masa del catalizador y el rendimiento es característico en los sistemas catalíticos y no puede asociarse con una pérdida de sitios activos de la hidrotalcita [195,196]. basicidad.…”
