Lignocellulosic biomass, especially lignin and extractives, has the potential to substitute fossil precursors in the chem. industry. The conversion of lignin has been intensively researched, but challenges remain as high temperatures and increased pressure are commonly used, which is not energy efficient. Lignin and wood extractives bear chromophoric groups that can absorb light in the UV region, which enables photochem. reactions. UV light emitting diodes (UV-LEDs) are an emerging technol.; they are cheap, versatile, and energy-efficient compared to existing mercury lamps. UV-LEDs were used in this study as a proof of concept for the valorization of a lignocellulosic residual stream from the pulp and paper industry, sawdust. In a process at ambient temperature and pressure and without the use of a catalyst, we have shown that lignin and extractives can be valorised using light from UV-LEDs. Simplified lignin model compounds were used to pinpoint chem. reactions during irradiation, and to ease the anal. of the sawdust samples. The rate of conversion upon irradiation of the model compounds was found to be 0.7-2.3 g L-1 h-1, depending on the concentration of the starting compounds This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2SDS of cas: 103-16-2).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.SDS of cas: 103-16-2
