Investigation Of Lauric Acid Conversion With The STA Incorporated Heterogeneous Catalysts In Liquid Phase Reaction

Öz

In this study, firstly the synthesis of acidic catalysts was carried out by loading the active compound silicotungstic acid(STA) with dry (W/Si:10-50%) and wet (W/Si:10%) impregnation methods into MCM-41 support material. These synthesized catalysts were used in the production of mono-di and tri laurin. The amount of active substance in the synthesized catalysts was determined by the ratios of tungsten in STA and silicon in MCM-41 structure. Moreover, W/Si: 10% by weight of STA was applied to the support material after the calcination process was loaded by dry impregnation method. Brønsted acid (BA) and Lewis acid (LA) regions of synthesized catalysts were determined by DRIFT analysis. The catalytic activities of the catalysts were determined by a glycerol-lauric acid esterification reaction in a batch reactor. The effect of calcination and active compound ratio with reaction temperature on the lauric acid conversion and mono-di and tri laurin selectivity was investigated. Furthermore, the esterification reaction of glycerol with lauric acid was carried out under the same conditions in the presence of a commercial catalyst Amberlyst-21. The experimental results of the synthesized catalysts and Amberlyst-21catalyst were compared. The synthesized catalysts after comparison were observed that have high catalytic activity. Lauric acid conversion and monolaurin selectivity have been obtained with W/Si: 10% catalyst (dry impregnation method) 3/3/1 molar ratio at383K after 6 hours 95% and 88%, respectively. XRD analysis was conducted on calcined-uncalcined MCM-41support material. Moreover, the structural properties of synthesized catalysts after the esterification reaction were determined by SEM-MAPPING analysis methods.
