Reaction Conditions:
with octadecyltriethoxysilane-treated high-silica Hβ-20 zeolite in water at 130; for 24 h;Reagent/catalyst;
Steps:
2.4. Catalytic tests
General procedure: The heterogeneous catalysts, stored under ambient conditions,were used for catalytic reactions without any pretreatment. Typically,ester (1 mmol), 1 mL H2O and 10 mg of catalysts and a magneticstarter bar were added to a reaction vessel (Pyrex pressuretube, 13 mL), and the mixture was heated at 130 °C under air withstirring at 300 rpm. For the catalytic tests in Table 1 and kineticstudy, conversions and yields were determined by GC-FID usingn-dodecane as an internal standard as follows. After completionof the reaction, acetone (7 mL) was added to the mixture, andthe catalyst was separated by centrifugation. Then, n-dodecane(0.2 mmol) was added to the reaction mixture, and the mixturewas analyzed by GC-FID and GC-MS. The GC-FID sensitivities ofthe products were determined using commercial carboxylic acidsor the isolated products after the reaction. For some of the productsin Tables 2 and 3, we determined isolated yields of the carboxylicacids as follows. After the filtration of the catalyst, followed bywashing the catalyst with acetone (6 mL), and by evaporation,the product was isolated by column chromatography using silicagel 60 (spherical, 63-210 μm, Kanto Chemical Co. Ltd.) with hexane/ethyl acetate (60/40-80/20) as the eluting solvent, followedby analyses by 1H NMR, 13C NMR and GC-MS equipped with thesame column as GC-FID.
