Function of aromatic compounds as indicators in laboratory experiments of heavy oil with fire flooding

open access: yesShiyou shiyan dizhi, 2022
Identifying whether high-temperature oxidation is realized in fire flooding has become one of the technical difficulties in evaluating the effect of fire flooding for heavy oil reservoirs. In order to study how the chemical properties of crude oil varied

Ultrasound-promoted synthesis of 2-organoselanyl-naphthalenes using Oxone® in aqueous medium as an oxidizing agent [PDF]

open access: yesPeerJ, 2018
A green methodology to synthesize 2-organoselanyl-naphthalenes based on the reaction of alkynols with diaryl diselenides is described. The electrophilic species of selenium were generated in situ, by the oxidative cleavage of the Se–Se bond of diaryl ...

Naphthalenes and Quinolines by Domino Reactions of Morita–Baylis–Hillman Acetates

open access: yesMolecules, 2020
An efficient synthetic route to highly functionalized naphthalenes and quinolines has been developed using domino reactions between Morita–Baylis–Hillman (MBH) acetates and active methylene compounds (AMCs) promoted by anhydrous K2CO3 in dry N,N ...

Contamination and sources of polychlorinated naphthalenes in the surface sediments of Chaobai River, China

open access: yesEcotoxicology and Environmental Safety, 2022
In aquatic systems, sediment is both a sink for persistent organic pollutants (POPs) and a potential source of POPs release. Consequently, it is important to understand the pollution characteristics and sources of polychlorinated naphthalenes (PCNs) as ...
