alpha-terpinene were demonstrated to be prohaptens able to induce contact allergy. The difference in sensitizing capacity of conjugated dienes as compared to alkenes with isolated doublebonds was found to be due to the high reactivity and sensitizing capacity of the allylic epoxides metabolically formed from conjugated dienes. We recommend that these structure-activity relationship rules are incorporated into

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 VIIIGroupmetals 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。
