Utilization of lignocellulosic biomass as a future energy source is a research field of widespread growth. The lignin fraction has potential as a renewable resource to provide building blocks for the chem. industry and is the most prominent source of bio-based aromatics Lignin, combined with formic acid and water under high temperature and pressure, is converted to a bio-oil rich in alkylated phenols and aliphatic hydrocarbons in a unique conversion process termed the LtL-process (lignin-to-liquid). In this work, this conversion technique has shown to be applicable to a variety of lignins, with organosolv extracted lignin as the main focus because of its high purity. The organosolv lignins appeared to be well suited for LtL-conversion generating higher yields of bio-oil than a lignin-rich residue from enzymic hydrolysis. 31P-NMR and GC-MS showed that the O/C ratios of the bio-oils decreases with increasing reaction temperature during LtL-solvolysis due to a decrease in methoxylated phenols and an increase in phenols with no methoxy substituent. This was verified by partial least squares (PLS) regression anal. and elemental anal. of the feedstocks and resulting bio-oils, from which an effective hydrodeoxygenation during LtL-conversion was evident too. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Safety of 4-Hydroxy-3-methoxyphenethanol).
4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) 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. Polyesters are important plastics, with monomers linked by ester moieties. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Safety of 4-Hydroxy-3-methoxyphenethanol
