Hydrodeoxygenation (HDO) of isoeugenol (IE) was investigated using bimetallic iridium-rhenium and platinum-rhenium catalysts supported on alumina in the temperature and pressure ranges of 200-250 °C and 17-40 bar in nonpolar dodecane as a solvent. The main parameters were catalyst type, hydrogen pressure, and initial concentration. Nearly quantitative yield of the desired product, propylcyclohexane (PCH), at complete conversion in 240 min was obtained with Ir-Re/Al2O3 prepared by the deposition-precipitation method using 0.1 mol/L IE initial concentration. High iridium dispersion together with a modification effect of rhenium provided in situ formation of the IrRe active component with reproducible catalytic activity for selective HDO of IE to PCH. The reaction rate was shown to increase with the increasing initial IE concentration promoting also HDO and giving a higher liquid phase mass balance. Increasing hydrogen pressure benefits the PCH yield.

异丁香酚在氧化铝负载的Ir，Pt和Re催化剂上的加氢脱氧
研究了异丁香酚（IE）的加氢脱氧（HDO），使用负载在氧化铝上的双金属铱-and和铂-ium催化剂在200-250°C和17-40 bar的温度和压力范围内在非极性十二烷中作为溶剂。主要参数是催化剂类型，氢气压力和初始浓度。使用通过沉积沉淀法使用0.1 mol / L IE初始浓度制备的Ir-Re / Al2O3，在240分钟内完全转化时，所需产物丙基环己烷（PCH）的收率接近定量。铱的高分散性以及effect的改性作用提供了IrRe活性成分的原位形成，具有可重现的IE对PCH选择性HDO催化活性。反应速率显示出随着初始IE浓度的增加而增加，还促进了HDO并给出了更高的液相质量平衡。氢气压力的增加有利于PCH的产率。
