Kinetics of Homogeneous Reaction of Potassium Methoxide Based on K2CO3 Catalyst in Transesterification of RBDPO to Biodiesel

Science and Technology Indonesia
Biodiesel production is generally catalyzed by potassium methylate or sodium methylate catalysts based on KOH and NaOH and these catalysts are still imported. The search for a cheap and effective catalyst continues to be carried out by researchers.

Conversion of Glucose to 5-Hydroxymethylfurfural in a Microreactor

Frontiers in Chemistry, 2020
5-hydroxymethylfurfural (5-HMF) is one of the key bio-based platform chemicals for the production of high-value chemicals and fuels. The conventional production of 5-HMF from biomass is confronted by the relatively low yield and high production cost.

Hydrothermal Synthesis of Siderite and Application as Catalyst in the Electro-Fenton Oxidation of p-Benzoquinone

Molecules, 2022
A weak aspect of the electro-Fenton (EF) oxidation of contaminants is the dependence of the Fenton reaction on acidic pH values. Therefore, the rationale of this work was to develop a novel catalyst capable of promoting the EF oxidation process at near ...

Effect of substrate and catalyst chirality on the diastereoselective epoxidation of R-(+)-limonene with manganese(III) salen complexes

Revista Facultad de Ingeniería Universidad de Antioquia, 2013
The asymmetric epoxidation of R-(+)-limonene in the presence of the Jacobsen´s catalyst in its chiral and achiral either homogeneous or heterogeneous (immobilized on Al-MCM-41) forms was studied using in situ generated dimethyldioxirane as oxidizing ...
