CH2 Linkage Effects on the Reactivity of Bis(aminophosphine)–Ruthenium Complexes for Selective Hydrogenation of Esters into Alcohols

open access: yesScientific Reports, 2017
A novel ruthenium complex binding to two subtly different aminophosphine ligands, (o-PPh2C6H4CH2NH2)(o-PPh2C6H4NH2)RuCl2, was successfully isolated. This bis(aminophosphine)–ruthenium complex shows efficient activity in both dimethyl oxalate (DMO) and ...

Rate constants of oxidation of unsaturated fatty esters studied by chemiluminescence [PDF]

open access: yes, 2012
This study deals with oxidation kinetics of three unsaturated fatty esters: methyl oleate, methyl linoleate and methyl linolenate at temperatures ranging from 90 to 150 °C. The reaction was monitored by chemiluminescence. A kinetic model was derived from

Investigation of Lactones as Innovative Bio-Sourced Phase Change Materials for Latent Heat Storage

open access: yesMolecules, 2019
In the presented work, five bio-based and bio-degradable cyclic esters, i.e. lactones, have been investigated as possible phase change materials for applications in latent heat storage systems. Commercial natural lactones such as ε-caprolactone and &

Morphology–acidity synergy in ZSM-5 for selective para-xylene synthesis via CO2/H2-mediated toluene methylation

open access: yesJournal of CO2 Utilization
CO2/H2-mediated toluene methylation over metal oxide–zeolite bifunctional catalyst offers a sustainable route for para-xylene (PX) synthesis, yet how zeolite morphology and acidity synergistically govern this coupled process remains unclear.
