“…Owing to the excess amount of ethylene glycol, the kinetic characteristics of catalyst-free acetalization only depend on the furfural concentration, and therefore, the kinetic model was assumed to be pseudo-first-order. 33,51 As depicted in Figure 3(a), the k value (slope) increased as the reaction temperature increased, suggesting that increasing temperature is beneficial to catalyst-free acetalization of furfural and ethylene glycol, which is in agreement with the analysis results of reaction temperature optimization (Figure 2). Moreover, the FD formation rate increased with the reaction temperature elevating from 40 to 60 °C (Table 1), which further corroborated that increasing the reaction temperature was favorable for this transformation.…”

“…Los autores demostraron que el catalizador que contiene un 20% en peso de WOx resultó ser el más activo, atribuyendo este resultado a la alta dispersión del WOx, que conduce a una mayor acidez del catalizador. De esta manera, en 2 h se alcanzó una conversión de glicerol del 100% con un 97,4% de selectividad a solketal[152].En la Tabla 2-21 se resumen los resultados reportados por los diferentes autores.Valorización catalítica de bioglicerol para la obtención de aditivos para combustibles: reacciones de cetalización y esterificación…”
