The aim of this study was to explore the conversion mechanism of α-O-4 linkage lignin dimer model compound (monobenzone) in supercritical ethanol. The decomposition processes of monobenzone were investigated at different reaction time (0-12 h), conversion temperature (250-310 °) and initial concentrations (0.01-0.03 g/mL). The reaction mechanism and pathways were proposed based on the distribution of products, the bond dissociation energies and the free radical theory. The results showed almost complete degradation was achieved in supercritical ethanol system. A higher temperature, a longer reaction time and a higher initial concentration significantly promoted the formation of solid residue due to the condensation reactions of the degradation intermediates/products. Based on the formation mechanism of products, the conversion products were classified into three types: (1) its own fragmentation compounds, (2) condensation compounds of its intermediates and (3) the second fragmentation compounds of its intermediates. A depolymerization reaction mechanism of monobenzone that primarily involved homolytic cleavage of the Cα-O linkage was proposed. In addition, the bibenzyl were an important and unstable intermediate product, it can continue to produce many different radical species that can participate in a variety of reaction mechanisms, resulting in complex reaction pathways and products distribution, even forming higher-mol. weight solid residue. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Computed Properties of C13H12O2).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Computed Properties of C13H12O2
