Heterogenisation of ketone catalysts within mesoporous supports for asymmetric epoxidation

, 2013
The synthesis of the first mesoporous silica (150 Å) anchored carbohydrate-derived chiral ketone is described. This new heterogeneous catalyst has been shown to be effective in the asymmetric epoxidation of olefins by oxone.

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.
