‘Lignin and extractives first’ conversion of lignocellulosic residual streams using UV light from LEDs was written by Hynynen, Jonna;Riddell, Alexander;Achour, Abdenour;Takacs, Zoltan;Wallin, Mats;Parkaas, Jim;Bernin, Diana. And the article was included in Green Chemistry in 2021.Application In Synthesis of 4-Benzyloxyphenol The following contents are mentioned in the article:

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: 103-16-2Application In Synthesis of 4-Benzyloxyphenol).

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. Polyesters are important plastics, with monomers linked by ester moieties. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Application In Synthesis of 4-Benzyloxyphenol

Two different new calamitic liquid crystals (LCs), 4-[4-(((S)-3,7-dimethyloctyloxy)phenoxy)carbonyl]phenyl 4-(n-decyloxy)benzoate (DPDEB) and 4-[4-(((S)-3,7-dimethyloctyloxy)phenoxy)carbonyl]phenyl 4-(n-dodecyloxy)benzoate (DPDOB) were synthesized and characterized using ¹H-NMR, and ¹³C-NMR. The LC behavior of the target compounds was investigated by optical polarization microscopy (PM) and differential scanning calorimetry (DSC). The selectivity coefficients, a, of the structural isomers at infinite dilution for the DPDEB and DPDOB LCs were determined for Bu acetate, Bu alc. and amyl alc. isomers. Surface energy anal. has been performed using inverse gas chromatog. (IGC). By using suitable solvents, the surface properties and separation power of isomers of DPDEB and DPDOB LCs were determined between 303.2 and 323.2 K. Experiments with LC’s have been conducted at infinite dilution to the specific adsorption enthalpy and the specific adsorption free energy. IGC measurements exhibited values of acidity constants (K_A) of 0.033 and 0.057 and basic constants (K_D) of 0.176 and 0.242 for DPDEB and DPDOB, resp. It has been found that all LCs show basic character. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Quality Control of 4-Benzyloxyphenol).

4-Benzyloxyphenol (cas: 103-16-2) 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, including apples, durians, pears, bananas, pineapples, and strawberries. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Quality Control of 4-Benzyloxyphenol

Polyesters are important plastics, with monomers linked by ester moieties. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Synthetic Route of C13H12O2

Catalytic hydrogenolysis of lignin β-O-4 aryl ether compound and lignin to aromatics over Rh/Nb₂O₅ under low H₂ pressure was written by Guan, Weixiang;Chen, Xiao;Hu, Haoquan;Tsang, Chi-Wing;Zhang, Jie;Lin, Carol Sze Ki;Liang, Changhai. And the article was included in Fuel Processing Technology in 2020.Computed Properties of C13H12O2 The following contents are mentioned in the article:

The increasing risk of fossil fuels depletion due to surging energy demand has accelerated the search of alternative renewable sources. Lignin, one of the major components of lignocellulosic biomass, is the only abundant renewable natural resource for aromatic compounds In this work, the effects of metals and process parameters were discussed via the catalytic hydrogenolysis of β-O-4 lignin model compound, 2-phenethyl Ph ether. The best results were obtained over Rh/Nb₂O₅ with an overall conversion of 99.3% and exceptional selectivity of 98.9% to aromatic products when the hydrogenolysis was carried out at 260° and 0.1 MPa H₂ for 4 h. The high efficiency is mainly attributed to the cooperation between Rh and NbOx at the perimeter sites, in which Rh particles are responsible for the dissociation of H₂ and NbOx for activating C-O bonds. With respect to depolymerize of ash wood lignin, the liquid products were mostly aromatics over Rh/Nb₂O₅ under 0.1 MPa H₂. The results achieved in this work provide a promising prospect towards valorization of lignin into production of valuable aromatic compounds under low hydrogen pressure.

Rapid phenolic O-glycosylation of small molecules and complex unprotected peptides in aqueous solvent was written by Wadzinski, Tyler J.;Steinauer, Angela;Hie, Liana;Pelletier, Guillaume;Schepartz, Alanna;Miller, Scott J.. And the article was included in Nature Chemistry in 2018.Category: ethers-buliding-blocks The following contents are mentioned in the article:

Glycosylated natural products and synthetic glycopeptides represent a significant and growing source of biochem. probes and therapeutic agents. However, methods that enable the aqueous glycosylation of endogenous amino acid functionality in peptides without the use of protecting groups are scarce. Here, we report a transformation that facilitates the efficient aqueous O-glycosylation of phenolic functionality in a wide range of small mols., unprotected tyrosine, and tyrosine residues embedded within a range of complex, fully unprotected peptides. The transformation, which uses glycosyl fluoride donors and is promoted by Ca(OH)₂, proceeds rapidly at room temperature in water, with good yields and selective formation of unique anomeric products depending on the stereochem. of the glycosyl donor. High functional group tolerance is observed, and the phenol glycosylation occurs selectively in the presence of virtually all side chains of the proteinogenic amino acids with the singular exception of Cys. This method offers a highly selective, efficient, and operationally simple approach for the protecting-group-free synthesis of O-aryl glycosides and Tyr-O-glycosylated peptides in water. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Category: ethers-buliding-blocks).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water.

Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

para-selective hydroxylation of alkyl aryl ethers was written by Zhu, Runqing;Sun, Qianqian;Li, Jing;Li, Luohao;Gao, Qinghe;Wang, Yakun;Fang, Lizhen. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2021.Quality Control of 4-Benzyloxyphenol The following contents are mentioned in the article:

Para-Selective hydroxylation of alkyl aryl ethers is established, which proceeds with a ruthenium(II) catalyst, hypervalent iodine(III) and trifluoroacetic anhydride via a radical mechanism. This protocol tolerates a wide scope of substrates and provides a facile and efficient method for preparing clin. drugs monobenzone and pramocaine on a gram scale. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Quality Control of 4-Benzyloxyphenol).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. 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.Quality Control of 4-Benzyloxyphenol
