On December 1, 2020, Solomonov, Boris N.; Yagofarov, Mikhail I. published an article.Synthetic Route of 91-16-7 The title of the article was An approach for the calculation of vaporization enthalpies of aromatic and heteroaromatic compounds at 298.15 K applicable to supercooled liquids. And the article contained the following:

An approach for the calculation of the vaporization enthalpies of aromatic and heteroaromatic compounds at T = 298.15 K with accuracy competitive with experiment was proposed. The vaporization enthalpies may be calculated from the solution enthalpies of liquid and solvation enthalpies in benzene. The solution enthalpies of liquids were shown to be constant within a given type of aromatic compounds For a set of 67 liquid and 41 solid aromatic and heteroaromatic compounds not capable of intermol. hydrogen bonding, it was exptl. demonstrated that the solution enthalpies of liquids or supercooled liquids in benzene were equal to 1 ± 1 kJ·mol-1. The way to consider intermol. hydrogen bonding, e.g., in phenol, aniline, pyrrole derivatives, was also proposed. The methods for solvation enthalpy calculation were proposed previously. The calculated and literature vaporization enthalpies values of 415 aromatic and heteroaromatic compounds were compared. Average absolute deviation amounted to 1.3 kJ·mol-1. The proposed approach is especially valuable for calculation of the vaporization enthalpies of low-volatile compounds, including those solid at T = 298.15 K. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Synthetic Route of 91-16-7

On April 13, 2004, Kim, Yun-Hi; Ahn, Jun-Hwan; Shin, Dong-Cheol; Kwon, Soon-Ki published an article.HPLC of Formula: 146370-51-6 The title of the article was Synthesis and characterization of poly(terphenylenevinylene) derivatives containing alkoxy substituents and (or) phenyl pendant group. And the article contained the following:

The blue electroluminescent polymers, poly(terphenylenevinylene) derivatives that have advantages of PPP and PPV, were prepared by Suzuki coupling reaction. The structure and properties of the polymers were analyzed by various spectroscopic methods. Poly(MHTPPV) and poly(TPPV) with Ph pendant group in a vinyl bridge showed blue shifted absorption spectra, large band gap and enhanced thermal stability as compared with that of poly(MHTPV). The PL spectra of the films of the polymers showed maximum peaks at 450-460 nm, which are pure blue emissions. The blue electroluminescence (λmax=450-460 nm) was obtained with the turn on voltage of 8-10 V, when the simple light-emitting diodes of ITO/polymer/Al were fabricated. The excimer emission due to interchain interaction was reduced by the introduction of substituents into the vinyl bridge and (or) the main chain. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).HPLC of Formula: 146370-51-6

Coulomb, Julien; Certal, Victor; Larraufie, Marie-Helene; Ollivier, Cyril; Corbet, Jean-Pierre; Mignani, Gerard; Fensterbank, Louis; Lacote, Emmanuel; Malacria, Max published an article in 2009, the title of the article was Intramolecular Homolytic Substitution of Sulfinates and Sulfinamides.Formula: C8H10BrNO And the article contains the following content:

A general and efficient method for the synthesis of cyclic sulfinates and sulfinamides based on intramol. homolytic substitution (SHi) at the sulfur atom by aryl or alkyl radicals is described. Both alkyl and benzofused compounds can be accessed directly from easily prepared acyclic precursors. Enantiomerically enriched sulfur-based heterocycles were formed through an SHi process with inversion of configuration at the sulfur atom. Cyclization of prochiral radicals proceeded with varying stereochem. outcomes, depending on the size of the incoming radical. 2-Pyridyl and 2-quinolyl radicals led to biaryl compounds, which result from attack onto the ortho position of the arylsulfinate rather than a thiophilic substitution. The experimental process involved the reaction of (2-Bromo-5-methoxyphenyl)methanamine(cas: 887581-09-1).Formula: C8H10BrNO

Shankar, Jaya Seeli; Kumar, Sangeetha Ashok; Periyasami, Bhuvana K.; Nayak, Sanjay K. published an article in 2020, the title of the article was Mechanism of photoinduced charge transfer at MEH-PPV and titanium dioxide nanoparticle interface.Recommanded Product: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene And the article contains the following content:

In this study, we investigated mechanisms of photoinduced electron transfer from a conjugated polymer poly(2-methoxy-5-(2-ethylhexyloxy)1,4-phenylenevinylene) (MEH-PPV) to titanium dioxide (TiO2) nanoparticles (acceptor) through steady-state photoluminescence (PL) spectroscopy. Since mixed phase TiO2 has better photocatalytic compared to single phase, it is an efficient charge separation process during photoexcitation of polymer nanocomposites by incorporating the mixed phase TiO2 nanoparticles into the MEH-PPV polymer matrix through in situ polymerization Structural characterization revealed only phys. interaction between the polymer matrix and dispersed nanoparticles. The absorbance spectra of nanocomposites also indicated the absence of ground state complex formation. Luminescence quenching of polymer nanocomposites compared to pristine MEH-PVV signifies the charge transfer taking place at the MEH-PPV/TiO2 interfaces. Thus, the MEH-PPV/ mixed phase TiO2 nanocomposite serves as an active layer for photovoltaic application. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Recommanded Product: 1-((2-Ethylhexyl)oxy)-4-methoxybenzene

Adilina, Indri Badria; Widjaya, Robert Ronal; Hidayati, Luthfiana Nurul; Supriadi, Edi; Safaat, Muhammad; Oemry, Ferensa; Restiawaty, Elvi; Bindar, Yazid; Parker, Stewart F. published an article in 2021, the title of the article was Understanding the Surface Characteristics of Biochar and Its Catalytic Activity for the Hydrodeoxygenation of Guaiacol.Formula: C8H10O2 And the article contains the following content:

Biochar (BCR) was obtained from the pyrolysis of a palm-oil-empty fruit bunch at 773 K for 2 h and used as a catalyst for the hydrodeoxygenation (HDO) of guaiacol (GUA) as a bio-oil model compound Brunauer-Emmet-Teller surface area anal., NH3 and CO2-temperature-programmed desorption, scanning electron microscope-dispersive X-ray spectroscopy, CHN anal. and X-ray fluorescence spectroscopy suggested that macroporous and mesoporous structures were formed in BCR with a co-presence of hydrophilic and hydrophobic sites and acid-base behavior. A combination of IR, Raman and inelastic neutron scattering (INS) was carried out to achieve a complete vibrational assignment of BCR. The CH-OH ratio in BCR is ∼5, showing that the hydroxyl functional groups are a minority species. There was no evidence for any aromatic C-H stretch modes in the IR, but they are clearly seen in the INS and are the majority species, with a ratio of sp3-CH:sp2-CH of 1:1.3. The hydrogen bound to sp2-C is largely present as isolated C-H bonds, rather than adjacent C-H bonds. The Raman spectrum shows the characteristic G band (ideal graphitic lattice) and three D bands (disordered graphitic lattice, amorphous carbon, and defective graphitic lattice) of sp2 carbons. Adsorbed water in BCR is present as disordered layers on the surface rather than trapped in voids in the material and could be removed easily by drying prior to catalysis. Catalytic testing demonstrated that BCR was able to catalyze the HDO of GUA, yielding phenol and cresols as the major products. Phenol was produced both from the direct demethoxylation of GUA, as well as through the demethylation pathway via the formation of catechol as the intermediate followed by deoxygenation. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Formula: C8H10O2
