Alcoholysis is a promising approach for converting biomass into fuels and/or chems. under mild conditions. However, the effect of pretreatment on biomass alcoholysis was rarely reported. Herein, the effect of pretreatment with H2O2 on sweet sorghum stalk (SSS) methanolysis was examined The results show that the pretreatment could markedly improve the bio-oil (BO) yield and decrease the appropriate temperature for obtaining maximum BO yield. The appropriate temperature for pretreated SSS methanolysis was determined to be 280 °C and the maximum BO yield is 44 wt%. In addition, higher heating values of the BOs were also enhanced based on elemental anal. According to anal. with gas chromatograph/mass spectrometer, phenolic compounds, esters, and sugars are predominant in the BOs, and the yield of phenolic compounds significantly increased from 91.75 to 111.68 mg·g-1 by the pretreatment. Moreover, polar species in the BOs decreased and deoxygenation occurred during pretreated SSS methanolysis. Analyses with scanning electron microscope and N2 physisorption reveal that pretreated SSS has more grooves and higher sp. surface area and anomalous porosity than SSS. According to analyses with Fourier transform IR spectrometer and X-ray photoelectron spectrometer, oxygen functional groups mainly in the forms of C=O and COO were introduced into SSS by the pretreatment. The changes of phys. and chem. structures should be responsible for enhancing SSS methanolysis and property of the BO. In the experimental materials used by the author, we found Methyl 3-oxovalerate(cas: 30414-53-0Computed Properties of C6H10O3)
Methyl 3-oxovalerate(cas: 30414-53-0) belongs to ketone compounds. Ketone compounds have important physiological properties. They are found in several sugars and in compounds for medicinal use, including natural and synthetic steroid hormones. Molecules of the anti-inflammatory agent cortisone contain three ketone groups.Computed Properties of C6H10O3
