Abstract In this study first different SiO2 Al2O3 ratios of Al MCM 41 according to previous reports were synthesized and various amounts of H3PO4 were loaded on Al MCM 41 These catalysts were used in vapour phase esterification to produce of hexyl acetate and butyl acetate High conversion and selectivity were obtained Some techniques such as BET XRD Si MAS NMR were used for investigating the structural properties of these catalysts The optimized catalyst was selected The operational factors such as reaction temperature molar ratio of reactants SiO2 Al2O3 ratio of catalyst H3PO4 feed flow rate were examined Finally the catalytic efficiency of each catalyst was tested for 18h The results showed that 30 H3PO4 Al MCM 41 70 was more active than the other catalyst for esterification of acetic acid with 1 hexanol and Al MCM 41 150 showed the best results for esterification of acetic acid with 1 butanol The hydrophobic properties total acidity of catalyst and length of alkyl group were suggested to play important roles in the conversion and selectivity
