Synthesis of diols from jojoba oil via rhodium-catalyzed reductive hydroformylation: a smart way to access biobased polyurethanes

Abstract

Jojoba oil ester has been functionalized with alcohol groups via hydrohydroxymethylation (HHM) catalyzed by a Rh/amine system. In the optimized conditions, a full conversion together with a 99% yield in...

Synthesis of sustainable eugenol/hydroxyethylmethacrylate-based polymers with antioxidant and antimicrobial properties

“…10 Over the years a number of strategies has been adopted to achieve antimicrobial properties, 11–13 among which the most relevant are those relying on the use of natural compounds. 14–18…”

“…10 Over the years a number of strategies has been adopted to achieve antimicrobial properties, [11][12][13] among which the most relevant are those relying on the use of natural compounds. [14][15][16][17][18] In this framework, the synthesis of eugenol-based polymers is a quite relevant topic for the pharmaceutical field and may contribute to overcoming some issues related to the delivery of antioxidants as well as to counteracting microbial infections. 20 EU has several reactive groups, namely the phenol group, the allyl group and the free positions of the aromatic ring.…”

Versatile Epoxidized Soybean Oil-Based Resin with Excellent Adhesion and Film-Forming Property

“…Plant oils (POs) as abundantly available and renewable feedstocks have attracted tremendous interest in developing novel polymers to replace petroleum-based counterparts because of increasing concern regarding the depletion of fossil reserves and environmental issues. , To obtain high-performance polymers, modifications are necessary for most POs as they are not reactive enough in polymerization reactions. Various modifications, including epoxidation, hydroformylation, hydrogenation, transesterification, amidation, acrylation, and so on, are employed to obtain reactive PO-based monomers for further utilization in various fields.…”
