The effect of O2 and NO2 on the ring retaining products of the reaction of benzene with hydroxyl radicals. Monat- shefte fur Chemie 127, 875-881.Moschonas, N., Danalatos, D., and Galvas, S., 1999: The effect of O 2 and NO 2 on the ring retaining products of the reaction of ...
It was observed that a polar substituent in the benzene ring mainly affected ka in the nitric acid oxidation of diphenylmethanes. The mechanism of reaction of these benzyl compounds is discussed.doi:10.1016/S0040-4020(01)93076-5Y. Ogata
Moreover, some researchers also believe that the stronger pharmacological activities of CAPE-pNO2 may be due to the increased nitro group, an electron withdrawing group, which may decrease the cloud density of benzene ring, and change the bioactivities of CAPE-pNO2 [68]. Therefore, it is ...
Air pollution in São Paulo is constantly being measured by the State of Sao Paulo Environmental Agency, however there is no information on the variation between places with different traffic densities. This study was intended to identify a gradient of exposure to traffic-related air pollution with...
High Accuracy and Reliability: This nitrogen dioxide gas sensor (TB200B-ES1/ES4-NO2-1000) offers a high level of accuracy, with a 5% full-scale accuracy and a repeatability of less than 2%. This ensures precise readings and reliable results in air quality monitoring applications. ...
(HEDMs),extensive theoretical calculations were carried out to investigate on a series of polynitrotriprismanes (PNNPs): C6H6-n(NO2)n (n= 1-6).Heats of formation (HOFs), strain energies (SE), and disproportionation energy (DE) were obtained using B3LYP/6-311+G(2df,2p)//B3LYP/6-31...
On the other hand, the Bird index indicates that phosphorine is less aromatic than arsabenzene. Therefore, it is also interesting to investigate the effect of the substituent and its position on the aromaticity of the ring. Table 2. Selected characteristics of ring atoms. Compound C6H6 C5H5N ...
On the other hand, the LUMO orbital showed significant differences between the compound Azo1 and its nitro congeners (Azo2 to Azo4). In Azo1, the LUMO orbital is related to a pi delocalization system that encompasses the phenyl azo ring, the phenol ring, and the imine group, while in ...
