Web22 mrt. 2024 · A bio-based vanillin epoxy (VE) is synthesized from the lignin-derived vanillin, and a thermoset resin is prepared after mixing it with a 4,4′-diaminodiphenyl methane (DDM) hardener. Further, it is infused in high-cellulose-containing alkali-treated jute fiber (TJF) mats through a simple approach to enhance the adhesion between the VE-DDM … WebThe product formed is chloromethane, which is one H-atom from the methane group is replaced by a Cl atom, hence this reaction is a substitution reaction. But this reaction will not get stopped over here, the reaction will further continue and all the H-atoms in methane will get replaced by Cl atoms.
