摘要： 在超临界CO2条件下采用Pd/C催化剂进行催化松香加氢反应的研究。超临界CO2条件与常规条件下反应产物相比较,产品中枞酸、去氢枞酸含量都较常规条件下的氢化松香产品低。详细考察了反应温度、反应时间、催化剂用量、催化剂重复使用对反应的影响。结果表明Pd/C催化剂中Pd的流失是造成催化剂失活的主要原因。

关键词: Pd/C, 氢化松香, 超临界CO2

Abstract: Hydrogenation of rosin over Pd/C catalysts was studied in supercritical CO2 (scCO2) phase. Comparison of results in scCO2 with those in conventional conditions showed that the product contained lower of abietic and hydroabietic acid. The effects of reaction temperature, reaction times, amount of Pd/C catalysts and the reuse of Pd/C catalysts were studied. The reason of the decrease of catalyst activity was the losing of Pd in Pd/C catalysts when were reused.

Key words: Pd/C catalyst, hydrogenated rosin, supercritical CO2 fluid
