Abstract

Seven acidic functional ionic liquids were prepared and used as catalysts in α-pinene esterification.A suitable ionic liquid [HSO3-pmim]H2PO4 was obtained and characterized by FT-IR,1H NMR and 13C NMR.The influences of factors on α-pinene esterification results were investigated and the obtained optimum conditions were n(α-pinene)∶n([HSO3-pmim]H2PO4)∶n(chloroactic acid)∶n(acetic acid)=5∶0.9∶5∶14,reaction temperature 40 ℃ and reaction time 10 h.Under above conditions,the conversion of α-pinene was 85.6% and the selectivity of terpinyl acetate was 36.0%.When the composite catalytic system was reused for 5 times,α-pinene conversion and selectivity of terpinyl acetate were still 83.5% and 33.7% respectively.
