Lignin, a component of the cell walls of plants and the second most abundant biopolymer has long been regarded as disturbing substance in pulp production by paper industry. This view has changed in recent decades. Thus, lignin is increasingly regarded as an alternative to crude oil. Tuned and modified lignins have suitable properties to use them as building blocks for various applications as well as for the production of basic chems. By modifying lignin, its reactivity and uniformity can be increased. In addition, properties of the lignin can be changed and influenced by selective modification. By a solvent-free modification with dihydroxybenzene, aliphatic OH groups of the lignin side chain can be removed and covalent C-C bonds to the aromatics can be formed. At the same time, aryl-alkyl ether cleavage occurs, which reduces the mol. weight of lignin by about one third. In addition, ongoing reactions result in the reduction in the mol. weight distribution. All this leads to a more uniform and reactive lignin which is interesting as a precursor for various applications. This work provides a deeper understanding of ongoing reactions with dihydroxybenzenes and the structure of modified lignins. 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 are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. 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.Safety of 4-Hydroxy-3-methoxyphenethanol
