“…5e and f) conrm its uniform hexagonal pore structure, which indicates the successful formation of the SBA-15. 31 Aer polymerisation with PNIPAM and PMAA, the average particle size increased to 970 nm. The black dots present in the inner pore channels of the PdNPs-SBA-15-PNIPAM/PMAA are attributed to the PdNPs, which conrms the incorporation of PdNPs into the SBA-15-PNIPAM/PMAA.…”

El uso de la biomasa como materia prima para la síntesis de diversos materiales es una actividad que continúa creciendo y ha permitido el desarrollo de nuevos procesos y productos, como la síntesis de bioplastificantes a base de ácidos orgánicos como el ácido succínico, y materiales carbonáceos a partir de azúcares, polímeros naturales como la celulosa, almidón, entre otros. Aquí hemos desarrollado una serie de catalizadores, entre ellos uno a base de almidón con propiedades ácidas, un material mesoporoso no cristalino como la SBA -15 con ZrO2 incorporado y sulfatada, y carbones impregnados con ácido dodecatungstofosfórico. Estos fueron probados en la reacción de esterificación de ácido succínico con etanol, empleando la resina ácida Amberlyst 36 como catalizador de referencia para comparar los catalizadores y estudiar la influencia de los parámetros de reacción.

“…The SBA‐15 mesoporous siliceous material was synthesized by hydrothermal treatment in a strongly acidic medium according to Valles et al. 38 by using the triblock copolymer Pluronic 123 (P123, Sigma‐Aldrich) as template and tetraethyl orthosilicate (TEOS, 98%, Sigma‐Aldrich) as source of silicon, with a molar gel composition of 1 TEOS:158 H 2 O:6 HCl:1.6 × 10 −2 P123. In a polypropylene container, 1.5 g of P123 and 48 mL of 2 M HCl were mixed at 50 °C with stirring.…”

“…Their particular textural properties make such materials of great interest for use as catalysts, adsorbents, and supports 31. The incorporation of heteroatoms such as aluminum, gallium, titanium, and zirconium into the SBA‐15 framework and occasionally treatment with mineral acids to generate Brønsted and Lewis acid sites is an attractive strategy for the preparation of solid acid catalysts for a wide variety of processes of industrial interest 32–38. The advantages of heteroatom incorporation are both modification of textural properties and development of acidic properties.…”

Catalytic esterification of succinic acid with ethanol to obtain diethyl succinate (DES), a nontoxic plasticizer, is reported. Three sulfated zirconias supported on SBA‐15 [SZ‐SBA‐15(X)] with Si/Zr molar ratios (X) of 10, 20, and 30 were synthesized and characterized. N2 adsorption/desorption isotherms and X‐ray diffraction patterns evidenced preservation of the ordered mesoporous structure of the catalysts after incorporation of Zr. Yields of DES greater than 85 % were obtained at the final reaction time by using SZ‐SBA‐15(10) and SZ‐SBA‐15(20) catalysts, which were higher than those achieved with Amberlyst 36. Reuse of the SZ‐SBA‐15(20) catalyst showed that, even though the structure of the support was preserved, decreases in sulfur concentration and in the DES yield occurred.
