| Abstract: | The solid base hydroxyapatite （HAP） was prepared by the precipitation method, and was characterized by XRD. The esterification of acetic anhydride and phenol to phenyl acetate, which was catalyzed by HAP, was studied. The yield ofphenyl acetate was up to 93.1% when the reaction was carried out with catalyst mass fraction in the total weight of the material 4 %, mole ratio of acetic anhydride to phenol 1.05 ; 1, reaction temperature 140- 150 ℃ and reaction time 3 h. And the stability of HAP was excellent. |
