The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Thermal decomposition [of peat] in aqueous media》. Authors are Kaganovich, F. L.; Rakovskii, V. E..The article about the compound:5-Iodo-2-furaldehydecas:2689-65-8,SMILESS:IC1=CC=C(O1)C=O).Category: naphthyridine. Through the article, more information about this compound (cas:2689-65-8) is conveyed.
cf. preceding and following abstracts In the presence of excess H2O and steam, sapon, of esters is much more complete than during other kinds of pyrolysis. Large increases in amounts of HCO2H recovered indicate its formation by reaction of H2O with methoxyfurfural. Saponification of phenylglucosides and similar compounds is responsible for the increased yields of phenols. For the highest yields of volatile fatty acids, the temperature of wet carbonization should be 350° and the moisture content of the initial product ≥75%. Humic and uronic acids form unstable hydrates during wet carbonization and the temperature of decarboxylation is depressed by as much as 100% hence larger amounts of CO2 are evolved at lower temperatures
There is still a lot of research devoted to this compound(SMILES：IC1=CC=C(O1)C=O)Category: naphthyridine, and with the development of science, more effects of this compound(2689-65-8) can be discovered.
