Highly Selective Hydrogenation of Tetralin to cis‐Decalin Using Ru Catalyst

Abstract

High activity Ru catalyst was prepared for the first time to produce cis‐decalin from tetralin hydrogenation. Supercritical CO2‐methanol method was used to prepare Ru supported catalyst. Using this catalyst, the yield of cis‐decalin could reach as high as 92.52%. Furthermore, the catalyst remained a high activity after five cycles.

Comparative Study on the Hydrogenation of Naphthalene over Both Al2O3-Supported Pd and NiMo Catalysts against a Novel LDH-Derived Ni-MMO-Supported Mo Catalyst

“…It was suggested that the competition for catalytic adsorption sites was responsible for inhibiting cis to trans isomerization up until significant tetralin conversion. Wang et al . synthesized a chromium-based metal organic framework (MOF) for use in tetralin hydrogenation reactions spanning 140–220 °C across a range of 30–70 bar H 2 .…”

“…It was suggested that the competition for catalytic adsorption sites was responsible for inhibiting cis to trans isomerization up until significant tetralin conversion. Wang et al 16 synthesized a chromium-based metal organic framework (MOF) for use in tetralin hydrogenation reactions spanning 140−220 °C across a range of 30−70 bar H 2 . The results indicated that a highly enriched cis/trans ratio was achieved across all levels of tetralin conversion, due to a greater adsorption facility for tetralin by the highly porous MOF support.…”
