Cryptomeria japonica was treated with 90% pyridinium chloride ([Py]Cl) and 10% water weight/weight solution at 80 and 120°C. Most hemicellulose in C. japonica was liquefied and over half the lignin in C. japonica was solubilized after treatments at 80 and 120°C. However, cellulose was mostly insoluble at 80°C and partially soluble at 120°C. The crystal structure of cellulose in the cell walls was retained after treatment at 80°C for 48 h. The degradation products from the polysaccharides were obtained in different yields. The 90% [Py]Cl and 10% water weight/weight solution is effective for the treatment of lignocellulosics, such as liquefaction of lignocellulosics and the production of useful low mol. weight compounds In the experiment, the researchers used many compounds, for example, Pyridinehydrochloride (cas: 628-13-7Reference of 628-13-7).
Pyridinehydrochloride (cas: 628-13-7) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of −48.7 × 10−6 cm3·mol−1.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ·mol−1 in the liquid phase and 140.4 kJ·mol−1 in the gas phase. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.Reference of 628-13-7
