摘要: We report pure formic acid-mediated liquefaction of chitin for the first time. Formic acid exhibited a remarkable ability in functionalization and depolymerization ball-milled as well proto-chitin raw shrimp shells. Up to 60% combined yield series structurally identified monomeric products was obtained after reaction at 100 °C 12 h. The product stream could also converge single compound, 5-(formyloxymethyl)furfural (FMF), 35% longer evolution monitored by electrospray ionization mass spectrometry (ESI-MS), key finding is that involves several major chemical events following sequence: (1) process starts with partial formylation hydroxyl groups side chains generating soluble polymeric derivatives; (2) catalyzes polymer chain breakage non-conventional, non-hydrolytic pathway forming dehydrated monomers oligomers; (3) continues, water accumulates system, which induces more monomer oligomer generation via hydrolysis, formation rehydrated products. As such, constantly generated subsequently consumed hydrolysis rehydration, making self-sustained one.
