Chitosan/MCM-41-SO3H composites as catalyst of the etherification of limonene

Results in Materials, 2021
Etherification of limonene with methanol, ethanol, 1-propanol, 2-propanol, 1-butanol and 2-butanol to ethers were performed using a mesostructured silica with sulfonic groups, like MCM-41-SO3H, immobilized in chitosan (CHT), as composite catalyst (MCM-41-

Taking electrodecarboxylative etherification beyond Hofer–Moest using a radical C–O coupling strategy [PDF]

Nature Communications, 2020
Since its discovery, the Hofer-Moest mechanism strongly limits the scope of electrochemical decarboxylative etherification. Here, the authors report the electrochemical conversion of carboxylic acids into alkyl benzotriazole ethers expanding the scope to

Etherification of Glycerol with Propylene or 1-Butene for Fuel Additives [PDF]

The Scientific World Journal, 2017
The etherification of glycerol with propylene over acidic heterogeneous catalysts, Amberlyst-15, S100, and S200 resins, produced mono-propyl glycerol ethers (MPGEs), 1,3-di- and 1,2-di-propyl glycerol ethers (DPGEs), and tri-propyl glycerol ether (TPGE).

Efficient synthesis of bioetheric fuel additive by combining the reductive and direct etherification of furfural in one-pot over Pd nanoparticles deposited on zeolites

Green Energy & Environment, 2023
Furfuryl ethers have been considered to be a promising fuel additive. One step reduction etherification of furfural over supported Pd catalysts provides a facile way for the preparation of furfuryl ether.

An investigation into the process intensification of gasoline etherification by coupling with membrane separation

Results in Engineering, 2023
The etherification of gasoline is an efficient approach to diminish the olefin content as well as improve the stability and octane number of the fuel. Nevertheless, the olefin conversion rate during the gasoline etherification process is restricted by ...
