P3.5 – Bio-based polymers based on dehydrovanillin.
Bio-based vanillin is a relevant building block for a plethora of green polymer concepts. It can be obtained from the oxidative depolymerization of Kraft lignin [1]. This bio-based vanillin provides a lower CO_2 footprint compared to synthetic vanillin and is potentially scalable. Here we explore bio-based polyether concepts based on dehydrovanillin. The synthesis of dehydrovanillin […]
P3.6 – Synthesis and characterization of epoxidized lignin
The development of bio-based epoxy resins from renewable feedstocks are significantly in high demand as a sustainable alternative to petroleum-derived polymers. In this study, lignin extracted from different sources, specifically spruce and oat husk, was utilized in both its non-fractionated and in different fractions/depolymerized forms. These lignin variants were chemically modified through epoxidation using epichlorohydrin […]
