Cornstalk liquefaction (CSL) in methanol, water or methanol/water mixed solvents was studied at 250-320 °C. Each reaction mixture was separated into extract 1 (E1, including the solute in filtrate and methanol-extractable portion), extract 2 (E2, methanol-inextractable but isometric carbon disulfide/acetone-extractable portion) and residue (isometric carbon disulfide/acetone-inextractable portion) by filtration and sequential extraction with methanol and isometric carbon disulfide/acetone mixed solvent. The cornstalk, E1, E2 and the residues were analyzed using a Fourier transformation IR spectrometer and each E1 was analyzed using a gas chromatog./mass spectrometer. The microstructures of the cornstalk and its derived residues were observed with a scanning electron microscope. The results show that methanol and water exhibited a synergic effect on the CSL. The isometric methanol and water mixed solvent was found to be most effective for CSL at 300 °C for 30 min. Under such conditions, the total yield of gases, E1 and E2 and the yield of E1 reached 88.1% and 52.4%, resp. The yields decreased as the temperature or time was further increased, suggesting that some of the extractable species were repolymd. at higher temperatures or for prolonged time. E1 consisted of hydrocarbons, alkanols, tetrahydrofuranylmethanols, arenols, methoxyalkanes, methoxyarenes, ketones, carboxylic acids, esters, chloromethylbenzenes, nitrogen-containing species and several other species. In the experiment, the researchers used many compounds, for example, 1-Methyl-4-nitroimidazole (cas: 3034-41-1Computed Properties of C4H5N3O2).
1-Methyl-4-nitroimidazole (cas: 3034-41-1) belongs to imidazole derivatives. The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with a Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.Computed Properties of C4H5N3O2
