摘要： 在超临界二氧化碳流体下,用SO42-/Zr-MCM-41中孔分子筛作催化剂催化α-蒎烯水合反应.SO42-/Zr-MCM-41在超临界CO2下比常规条件下显示出对松油醇更高的选择性,并保持了在常规条件下的高催化活性.考察了在超临界CO2条件下,不同反应条件对反应的影响,得到了较佳的工艺条件,即:氯乙酸、松节油及水的物质的量之比为1:1:3,催化剂用量为松节油质量的7.5%,Si/Zr物质的量之比1:0.05,60℃反应8 h.在此条件下,松节油的转化率达94%,对松油醇的选择性达88%.

Abstract: The hydration of α-pinene to α-terpineol was studied using SO42-/Zr-MCM-41 mesoporous molecular sieves as catalyst in supercritical carbon dioxide (SCCD) for the first time. The reaction results showed that SO42-/Zr-MCM-41 was of better selectivity to the α-terpineol in SCCD than in conventional conditions, and was of similar catalytic activity in SCCD as in conventional conditions. The effects of preparing conditions of catalysts and the reaction conditions on the reaction results in SCCD were examined and the optimum conditions were obtained as follows:mass ratio of chloroacetic acid: turpentine: water 1:1:3,dosage of catalyst 7.5% of turpentine (mass),mass ratio of Si/Zr 1:0.05, reaction temperature 60℃ of 8h. Under the optimum conditions, the conversion of pinene is 94%, and the selectivity to terpineol can reach 88%.

Key words: supercritical carbon dioxide, hydration reaction, turpentine, acid catalysis
