Zeolite-based catalysts are versatile catalytic systems for a wide range of laboratory studies and industrial scale processes. The chemical composition, ion exchange, and pore size structure attributes of zeolites are responsible for their extensive catalytic applications. Esterification is one of the most important and routinely processes in diverse fields of organic synthesis. It has a long history in both industrial processes and laboratory work due to its versatility. This review intends to give a detailed insight into the significance of zeolite-based catalysts for ester bond formation

“…To optimize the biodiesel production, the catalyst with the best performance (C18) was used in a 2 3 directed design with four central points, using as input variables the amount of catalyst, methanol:oil molar ratio, and reaction time. The best reaction conditions to obtain up to 95% of biodiesel are shown in Table 3.…”

“…In this context, the use of heterogeneous catalysts seems as a feasible solution to overcome these problems, since the material can be separated from the product mixture and its nature is less aggressive than the basic remnants of homogeneous catalysts. Among the heterogeneous catalysts that have been explored in biodiesel production, we found waste materials [2], zeolites [3], and metal oxides, such as CaO, TiO 2 , MgO, and ZnO [4][5][6]. Sodium titanates are promising materials that have been studied for biodiesel production.…”

Sodium titanates were evaluated as heterogeneous catalysts for biodiesel production. Materials were prepared using an experimental design considering NaOH and TiO2 concentrations and hydrothermal and calcination temperatures as input variables. Materials characterization was carried out by DRX-Rietveld refinement, CO2-TPD, and XPS. Statistical analysis of the experimental results indicates that the calcination temperature is the most influential factor in the formation of sodium titanates with high catalytic performance in transesterification reactions. Further analysis of the oil-to-biodiesel conversion revealed that the catalytic activity of sodium titanates is directly correlated to the catalyst associated species and to the density of medium-strong basic sites on the surface of the material, obtaining up to 95% conversion to biodiesel at 60 °C using 3.6% weight catalyst with respect to oil.

“…Some studies are focused on the development of environmentally benign heterogeneous base‐catalyzed transesterification reactions , . Du et al reported preparation of NaY supported La 2 O 3 catalysts and its application in transesterification of castor oil to biodiesel . In some of our previous studies, acid‐base functionalized mesoporous MCM‐48, SBA‐15 and MCM‐41 were prepared using APTES (aminopropyl triethoxysilane) and MPTES (mercaptopropyl triethoxysilane) through post‐synthetic modification and were found to play significant role in transesterification of triacetin , …”

SAPO‐5 and SAPO‐34 materials were modified using post‐synthetic alkali treatment, which results in the formation of hierarchical SAPO‐5 and SAPO‐34 materials. To test the generation of mesoporosity, the modified materials were thoroughly characterized using XRD, FE‐SEM, TGA, ICP‐OES, and N2 adsorption/desorption techniques. Alkali treated SAPO‐5 and SAPO‐34 materials were utilized for the model reaction triacetin transesterification, under optimized conditions by varying the catalyst amount and reaction time: 90 % triacetin conversion with 66 % methyl acetate yield was achieved using modified SAPO‐5 catalyst, whereas 68 % triacetin conversion with 37 % methyl acetate yield was achieved using modified SAPO‐34 catalyst. The alkali treated SAPO‐5 catalyst was stable up to the 4th cycle.
