Catalytic Synthesis of Benzyl Acetate over Acid-Treated Crosslinked Montmorillonite
Abstract:
Crosslinked montmorillonite and the acid-treated crosslinked montmorillonite were studied by means of XRD,BET and SEM.For the 15%(mass fraction) acid-treated crosslinked montmorillonite,its surface area was 229 m2/g,d001=1.25 nm.Benzyl acetate was prepared directly from benzyl alcohol and acetic acid with acid-treated montmorillonite as the catalyst and toluene as the water stripping agent.The results show that the 15%(mass fraction) acid-treated crosslinked montmorillonite is an excellent catalyst.The optimum reaction conditions were that n(alcohol):n(acid) was 1:1.2,ω(cat)=0.4%,and the reaction time was 1.5 h.The esterification rate was about 99%.
