Debus radsizewski reaction

WebIn this work, a novel renewable taurine-based ionic liquid (IL), [TauIm][HSO4], was synthesized via the Debus–Radziszewski reaction. The synthesized IL was then used to produce ethyl levulinate (EL) from several lignocellulosic substrates under microwave irradiation. Experimental conditions (temperature, time, and IL quantity) for EL production … WebJun 1, 2024 · Very recently, Debus-Radziszewski (DB) reaction has been found to be able to synthesize main-chain polyimidazoliums in a greener, more simplified manner [49]. In the continuity of this synthetic breakthrough, a logical question in front of us is, would it be possible to synthesize porous PIL membranes directly from main-chain polyimidazoliums ...
