There are three peak groups of aromatic hydrocarbons (AHs) in the TICs of Biluo Co oil shale samples: a peak group of naphthalenes and alkyl naphthalenes, a peak group of phenanthrenes and alkyl phenanthrenes, and a peak group of aromatic sterenes and other polynuclear aromatic hydrocarbons (PAHs).
However, the samples used in this research were located outside the maturity centre, which shows that the methylated naphthalenes were affected by a factor other than thermal stress.
Through cleavages of bonds within the rings coupled with photochemical and acid catalyzed processes during diagenesis/catagenesis, these tetracyclic and pentacyclic aromatic hydrocarbons could be broken into methyl-substituted naphthalenes and phenanthrenes, respectively.
The mass chromatograms of naphthalenes, phenanthrenes and akyl derivatives of representative coal and shale extracts from the Maastrichtian Mamu Formation in the Anambra Basin are shown in Figures 4a-b and 5a-b, respectively.
The NOAA initially used gas chromatography-mass spectrophotometry (GC/ MS) with low detection limits, but the alkyl naphthalenes were omitted, thereby underestimating total naphthalene concentrations.
You may already know of naphthalenes from the mothballs in your closet.
In this study, baffles have been incorporated in both the roller bioreactor and BMB and mass transfer and bioremediation of pure naphthalene and methyl naphthalenes, as well as a mixture of these compounds are reported.
Kenplast G low-viscosity mixture of alkylated naphthalenes and phenanthrenes is an extender for epoxies, a secondary plasticizer for PVC, and a reportedly excellent compatibilizer for PVC/vinyl acetate combinations.
The polycyclic organic matter (POM) emitted at the highest rates were naphthalene and the monomethylated naphthalenes (1-methylnaphthalene and 2-methylnaphthalene).
Furthermore, radical-initiated reactions of naphthalene and alkyl-naphthalenes, which are also emitted in vehicle exhaust, produce what generally are the most abundant nitro-PAHs in ambient air, the semi-volatile nitronaphthalenes and methylnitronaphthalenes (Cecinato 2003; Gupta et al.
Key words: endocrine disruption, gonadotropins, 1,2,3,4,6,7-hexachlorinated naphthalene, in utero and lactational exposure, onset of spermatogenesis, polychlorinated naphthalenes, rats.
The researchers discovered that naphthalene -- a two-ring PAH found in exhaust -- can react with nitrogen dioxide, another important air pollutant, via a new mechanism involving unstable molecular fragments, or free radicals.
