contains the products of double bond hydrogenation, viz., cis- and trans-pinanes. The Ru, Rh, and Pd metals have a higher catalytic activity in β-pinene isomerization than Ir and Pt. Among the VIII Group metals studied, the Pd-based catalyst has the highest catalytic activity in double bond isomerization of α- and β-pinenes. The general scheme of the mechanism of hydrogenation and isomerization of α- and β-pinenes
研究了Pd/C、Ru/C、Rh/C、Pt/C和Ir/C催化剂上α-和β-蒎烯液相加氢和异构化的动力学规律,温度范围为20至100 °C,氢气压力为 1-11 bar,使用正辛烷作为溶剂。α-蒎烯和β-蒎烯在Ru/C、Rh/C、Pt/C和Ir/C催化剂上同时发生加氢和异构化反应,反应混合物中含有双键加氢产物,即顺式-和反式蒎烷。Ru、Rh 和 Pd 金属在 β-蒎烯异构化中比 Ir 和 Pt 具有更高的催化活性。在研究的 VIII 族金属中,Pd 基催化剂在 α- 和 β-蒎烯的双键异构化中具有最高的催化活性。
