摘要
以冰片、异冰片、乙酸、丙酸、丁酸、异丁酸为原料,首次采用纳米固体超强酸S2O28-/ZrO2催化合成了8个冰片、异冰片酯.酯化率42%～98%,反应选择性好,产物用1HNMR,13CNMR和IR进行结构确证.这些酯(除了乙酸冰片酯和乙酸异冰片酯外)的合成未见文献报道.
Using borneol, isobomeol, acetic acid, propionic acid, butyric acid and isobutyric acid as the raw materials and nanometer solid superacid S208^2-/ZrO2 as the catalyst for the first time, eight borneol and isobomeol ester compounds were prepared. Their yields were between 42% and 98% and the catalyst showed good selectivity. The structures of all these products were characterized by IR, ^13C NMR and ^1H NMR spectra. The synthesis of these esters except bornyl acetate and isobrnmyl acetate has not been reported.
