Valorization of chitin derived N-acetyl-D-glucosamine into high valuable N-containing 3-acetamido-5-acetylfuran using pyridinium-based ionic liquids was written by Zang, Hongjun;Lou, Jing;Jiao, Shuolei;Li, Huanxin;Du, Yannan;Wang, Jiao. And the article was included in Journal of Molecular Liquids in 2021.Safety of Pyridinehydrochloride This article mentions the following:
A series of pyridinium-based ionic liquids were synthesized to directly catalyze the conversion of N-acetyl-D-glucosamine (NAG, the monomer of chitin) to 3-acetamido-5-acetylfuran (3A5AF). The yield of 3A5AF in 1-carboxymethyl pyridinium chloride ionic liquid reached 37.49%, without any additives. Using B2O3 and CaCl2 as additives, the optimum yield increased to 67.37% at 180鎺矯 in 20 min. In addition, HPLC-MS anal. was utilized to elucidate the reaction mechanism. The research on turning “waste” into “wealth” opens up new ways for the utilization of biomass waste, which not only reduces environmental pollution but also has potential economic value. In the experiment, the researchers used many compounds, for example, Pyridinehydrochloride (cas: 628-13-7Safety of Pyridinehydrochloride).
Pyridinehydrochloride (cas: 628-13-7) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. Reduced pyridines, namely tetrahydropyridines, dihydropyridines and piperidines, are found in numerous natural and synthetic compounds. The synthesis and reactivity of these compounds have often been driven by the fact many of these compounds have interesting and unique pharmacological properties. Safety of Pyridinehydrochloride
