New Magnetic Fe Oxide-Carbon Based Acid Catalyst Prepared from Bio-Oil for Esterification Reactions

Prospectives for bio - oil upgrading via esterification over zeolite catalysts

A silica-based magnetic platform decorated with mixed ligand gold nanoparticles: a recyclable catalyst for esterification reactions.

A novel and convenient synthetic strategy for the preparation of magnetically responsive silica nanospheres decorated with mixed ligand protected gold nanoparticles is described. Gold nanoparticles are attached to the silica surface via stable amide bond formation. The hierarchical nanospheres show promising results as reusable and efficient catalysts for esterification reactions and they can b...

New Homogeneous And Robust Catalyst for Heck and Suzuki Reactions

In this work, different ethyl 2,4-dioxo-4-arylbutanoate derivatives were prepared and evaluated for their Src Kinase inhibitory activity. For this purpose, the appropriate substituted acetophenone derivatives reacted with diethyl oxalate in the presence of sodium ethoxide in dried ethanol to give the corresponding products. All compounds showed moderate activities comparing with staurosporine a...

Mesoporous Carbon Modified with Iron Oxide Based Magnetic Nanomaterials for Removal of Malachite Green Dye From Aqueous Solution

Mesoporous carbon (CMK-3) modified with Fe3O4 nanoparticles has been successfully synthesized and characterized by powder X-ray diffraction (XRD), N2 adsorption-desorption, scanning electron microscope (SEM) and transmission electron microscopy (TEM).The results depict that the synthesized Fe-CMK-3 preserved the ordered mesoporous structure of CMK-3, and magnetic species were dispersed insi...

Improving bio-oil quality and stability based on capping reactions

With the rapid development of global economy, there is an ever-growing demand for energy. The excessive use of traditional fossil fuel exposes the human to multiple environmental issues. As a promising technology, thermochemical conversion of biomass is able to provide not only environmental-friendly substitute fuel, but also other value-added chemicals. However, the complex composition and poo...
