Composition and structure characterization of coker gas oils derived from FCC decant oil before and after hydrotreating was written by Cai, Xinheng;Liu, Yingrong;Liu, Zelong;Fan, Qiming;Tian, Songbai. And the article was included in Shiyou Xuebao, Shiyou Jiagong in 2014.SDS of cas: 205-39-0 This article mentions the following:

Coker gas oils derived from FCC decant oil before and after hydrotreating were characterized by GC-FID/MS and NMR. A total of 121 aromatic compounds in the coke gas oils were identified and quantitated, including polycyclic aromatic hydrocarbons (PAHs), hydrogenated PAHs, C0-C2 substituted PAHs, thiophenic compounds and carbazoles. The compositional and structural changes in process of hydrotreating-delayed coking of FCC decant oil were also investigated. Coker gas oils derived from FCC decant oils with and without hydrotreating had different compound compositions, though their hydrocarbon group composition were quite similar. The gas oil from hydrotreated FCC decant oil had less unsubstituted polycyclic aromatic and heteroaromatic hydrocarbons, while more alkyl substituted aromatics and naphthenic-aromatics than that from the unhydrotreated one, implying that hydrotreating is beneficial for enhancing cracking and condensation reactions and improving liquid products in delayed coking of FCC decant oil. In the experiment, the researchers used many compounds, for example, Naphtho[2,1-b]benzofuran (cas: 205-39-0SDS of cas: 205-39-0).

Naphtho[2,1-b]benzofuran (cas: 205-39-0) belongs to benzofurans derivatives. Benzofuran derivatives have shown many biological activities, including antifungal and antimicrobial properties, and acting as antagonists of H3 receptors and angiotensin II. Substituted benzofurans find applications such as fluorescent sensors, oxidants, in drug discovery, and in another field of chemistry and agriculture.Recommanded Product: 205-39-0

Identification of methoxylated phenols as candidate tracers for atmospheric wood smoke pollution was written by Hawthorne, Steven B.;Miller, David J.;Barkley, Robert M.;Krieger, Mark S.. And the article was included in Environmental Science and Technology in 1988.Recommanded Product: 205-39-0 This article mentions the following:

More than 70 organic compounds were identified in unfractionated CH2Cl2 extracts of soot from residential wood stoves by a combination of capillary gas chromatog. coupled with low-resolution mass spectrometry (GC/MS), GC coupled with high-resolution mass spectrometry, and chem. ionization mass spectrometry with deuteriated methanol as the reagent gas. Thirty of the species are derivatives of guaiacol and syringol, which result from the pyrolysis of wood lignin. Soots from hardwood and pine show similar proportions of the syringol derivatives, but pine soot has much higher proportions of the guaiacol derivatives Samples collected onto filters backed up by polyurethane foam plugs in the cooled smoke plume showed that some of the methoxylated phenols were primarily in the vapor phase, whereas the majority were associated with the particulates. These species are expected to be unique to wood smoke in urban atms. and are therefore suggested as tracers for atm. wood smoke pollution.

Naphtho[2,1-b]benzofuran (cas: 205-39-0) belongs to benzofurans derivatives. Benzofurans are only weakly aromatic in nature and they are cleaved by many oxidative and reductive conditions. Benzofurans have also made significant and distinctive contributions to biology.

Di-tert-butylneopentylphosphine (DTBNpP): An Efficient Ligand in the Palladium-Catalyzed α-Arylation of Ketones was written by Raders, Steven M.;Jones, Jessica M.;Semmes, Jeffrey G.;Kelley, Steven P.;Rogers, Robin D.;Shaughnessy, Kevin H.. And the article was included in European Journal of Organic Chemistry in 2014.Application of 205-39-0 This article mentions the following:

Di-tert-butylneopentylphosphine (DTBNpP) and palladium(II) acetate provide an efficient catalytic system for the α-arylation of ketones. Aryl bromides were coupled with ketones using 0.25-0.5 mol-% Pd(OAc)2/DTBNpP in toluene at 50 °C, whereas aryl chlorides required a higher catalyst loading (0.5-2.0 mol-%) and a higher temperature (80 °C). Coupling of 2-bromophenol with ketones using the Pd/DTBNpP system provides an efficient route for the synthesis of benzofurans.

Aryl-Aryl Bond Formation by Flash Vacuum Pyrolysis of Benzannulated Thiopyrans was written by Amick, Aaron W.;Wakamiya, Atsushi;Scott, Lawrence T.. And the article was included in Journal of Organic Chemistry in 2008.Name: Naphtho[2,1-b]benzofuran This article mentions the following:

In contrast to fully unsaturated 7-membered ring sulfur heterocycles (thiepines), some of which extrude sulfur and give the ring-contracted hydrocarbon even at room temperature in solution, benzannulated thiopyrans (6-membered sulfur heterocycles) require flash vacuum pyrolysis (FVP) conditions in the gas phase at temperatures in the range of 1000-1200 °C to promote the corresponding reaction. Thus, FVP of benzo[kl]thioxanthene (1 = I) gives fluoranthene, and naphtho[2,1,8,7-klmn]thioxanthene (6 = VI) gives benzo[ghi]fluoranthene (7 = VII). FVP of thioxanthone gives fluorenone together with lesser amounts of dibenzo[b,d]thiophene from competing decarbonylation. In the experiment, the researchers used many compounds, for example, Naphtho[2,1-b]benzofuran (cas: 205-39-0Name: Naphtho[2,1-b]benzofuran).
