Catalytic synthesis of n-amyl acetate with ferrocene and molybdosilicic heteropoly substituted

Three kinds of ferrocene and molybdosilicic heteropoly substituted with Keggin structure were synthesized.The n-amyl acetate was synthesized from the reaction of acetic acid and n-amyl alcohol.The effects of molar ratio of n-amyl alcohol to glacial acetic acid,dosage of catalyst,reaction time on the esterification ratio and reuse of catalyst were discussed.The results showed that the Molar ratio of ethanol to acetic acid is 2.0∶1,the dosage of catalyst is 0.5% of the material gross,reaction time is 2.5 h.Moreover,after continuous use for three times,the activity of the catalyst hardly descend.
