Abstract:
Twenty-one core samples from the Carboniferous Keluke Formation in the Qaidam basin, NW China, have been geochemically characterized to investigate thermal maturation influence on the evolution behaviors of aromatic hydrocarbons and the validity of commonly used maturity parameters. The Keluke Formation was deposited in marine to continental transitional facies and dominated by type III kerogen. Rock-Eval Tmax and vitrinite reflectance (%Ro) measurement suggested that the studied samples are highly matured at peak oil to gas condensate generation stages. Most biomarkers lost their sensitivity

Abstract:
Using a combined directed ortho metalation (DoM) – Suzuki–Miyaura cross coupling – directed remote metalation (DreM) approach, the alkylphenanthrenes (APs) 1-methyl- (5a), 1,7-dimethyl- (5b), 2,7-dimethyl- (5c), 7-ethyl-1-methyl- (15), and 7-tert-butyl-1-methylphenanthrenes (27) have been synthesized in four to seven steps and 21%–36% overall yields. In contrast to classical protocols, this method, which may be scaled to gram quantities, provides single isomers of APs in high purity of value as analytical standards for environmental studies.

Radke et al. Claimed the drastic decrease in β/ α ratio is due to the organic facies. However, such a phenomena could be also possibly caused

According to the literature report, anhydrous pyrolysis of methylphenanthrenes transfer to each other, and the proposed mechanism was extramolecular rearrangement. Thus, in this study, hydrous and anhydrous pyrolysis of 9-methylphenanthrene were carried out. The results
