Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 3121-61-7, Name is 2-Methoxyethyl acrylate, molecular formula is C6H10O3, belongs to esters-buliding-blocks compound. In a document, author is Feng, Zixing, introduce the new discover, Quality Control of 2-Methoxyethyl acrylate.
The chemical and structural transformation of bamboo wastes during torrefaction process
To investigate the chemical and structural transformation of bamboo during torrefaction process, bamboo wastes were torrefied at temperatures of 200, 250, and 300 degrees C and residence times of 1.0, 1.5, and 2.0 hr, whose properties were determined by thermogravimetry coupled with mass spectrometry (PY-MS), Fourier transform infrared spectrometer (FTIR), X-ray diffraction (XRD), and solid-state nuclear magnetic resonance spectroscopy (NMR). The results showed that torrefaction improved the energy density and calorific value, reduced the volatile matters, and pollutant emission of bamboo wastes. The chemical and structural transformation of bamboo wastes was due to pyrolysis of some chemical groups. Torrefaction temperatures had the more significant effect than residence times. The energy enrichment factor (EEF), the calorific value improvement (CVI), and fuel ratio (FR) of torrefied bamboo wastes increased with the increase of torrefaction temperatures and residence times. When torrefaction temperatures increased to 300 degrees C, crystalline region of cellulose was destroyed. There were more than 10 families of pyrolysis products, including alcohol, acid, aldehyde, alkane, ester, ether, furan, ketone, phenol, etc. Torrefaction changed the chemical environment of H atoms from aromatics of guaiacs unit, beta-O-4 structure, beta-beta structure to xylan. The beta-O-4 bond was broken in guaiacle unit and formed aromatization and alkyl side chains. The results will be helpful to reveal torrefaction mechanism of bamboo wastes and further develop their add-valued utilization as energy products.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 3121-61-7. Quality Control of 2-Methoxyethyl acrylate.
