And the article was included in Journal of Industrial and Engineering Chemistry (Amsterdam, Netherlands) in 2022.Recommanded Product: 1,2-Propanediol This article mentions the following:
Reported the sustainable route for the synthesis of ionic carbon from bio-derived sugarcane-waste (Bagasse) and further anchoring with iminophosphine rhodium complex (Rh@BCNP) and utilized for tandem hydroformylation reaction. The SEM anal. confirmed the formation of spherical shape morphol. of carbon with sizes ranging from 30-150 nm. The successful functionalization of the iminophosphine rhodium complex on the carbon surface were determined by XPS, TEM, FE-SEM, 31P NMR, 13C CP-MAS-NMR and FTIR anal. Furthermore, ICP-OES anal. confirmed the presence of 0.307 mmoles/g of Rh and 0.484 mmoles/g of P on the carbon surface. Rh@BCNP catalyst was the best combination of triphenylphosphine ligand, imine and rhodium metal, resulting in hybrid material with some acidic properties of carbon that favor the selectivity towards linear products. Rh@BCNP showed remarkable catalytic performance under moderate reaction conditions (80°C, 40 bar (CO + H2)) in 5 h. This sharp divergence from other methods leading to linear amines and acetals results in a novel atom economic approach to synthesize pharmaceuticals and industrial products. The Rh@BCNP catalyst gave recyclability up to five cycles. In the experiment, the researchers used many compounds, for example, 1,2-Propanediol (cas: 57-55-6Recommanded Product: 1,2-Propanediol).
1,2-Propanediol (cas: 57-55-6) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.Recommanded Product: 1,2-Propanediol
