【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.更多还原

【Abstract】 Using borneol, isoborneol, acetic acid, propionic acid, butyric acid and isobutyric acid as the raw materials and nanometer solid superacid S2 O 82 - /ZrO2 as the catalyst for the first time, eight borneol and isoborneol 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 isobornyl acetate has not been re- ported.更多还原
