Abstract:

Large amounts of residual 1-methylnaphthalene are generated when 2-methylnaphthalene is extracted from alkyl naphthalene. In order to transform waste into assets, this study proposes a feasible process for preparing 2-methylnaphthalene from 1-methylnaphthalene through isomerization and crystallization. The 1-methylnaphthalene isomerization was carried out in a fixed-bed reactor over mixed acids-treated HBEA zeolite. The results showed that acidic properties of catalysts and reaction temperature were associated with the 2-methylnaphthalene selectivity, yield and catalytic stability. At a high r

Abstract:

This paper introduces the current technology of separating and refining β-methylnaphthalene from wash oil. On this basis, I propose a new production method of β-methylnaphthalene after many experiments. Industrial methylnaphthalene is washed twice with sulfuric acid and is distilled once. The content of β-methylnaphthalene is higher than 96%.The yield is 60%, which is higher than current domestic production levels.

Abstract:

1-Methylnaphthalene is a critical component for constructing fuel surrogates of diesel and aviation kerosene. However, the reaction pathways of 1-methylnaphthalene included in existing detailed chemical kinetic models vary from each other, leading to discrepancies in the simulation of ignition and oxidation processes. In the present study, reaction classes and pathways involved in the combustion of 1-methylnaphthalene were analyzed, and effects of rate constants of reactions related to 1-methylnaphthalene and its significant intermediates on ignition delay times and species concentration profi

ABSTRACT The highly enriched deltaproteobacterial culture N47 anaerobically oxidizes the polycyclic aromatic hydrocarbons naphthalene and 2-methylnaphthalene, with sulfate as the electron acceptor.

Abstract. Current atmospheric models do not include secondary organic aerosol (SOA) production from gas-phase reactions of polycyclic aromatic hydrocarbons (PAHs). Recent studies have shown that primary semivolatile emissions, previously assumed to be inert, undergo oxidation in the gas phase, leading to SOA formation. This opens the possibility that low-volatility gas-phase precursors are a potentially large source of SOA. In this work, SOA formation from gas-phase photooxidation of naphthalene, 1-methylnaphthalene (1-MN), 2-methylnaphthalene (2-MN), and 1,2-dimethylnaphthalene (1,2-DMN) is s

Abstract:

ABSTRACT An active sulfate-reducing consortium that degrades 2-methylnaphthalene (2-MNAP) at rates of up to 25 μM day−1 was established. Degradation was inhibited in the presence of molybdate and ceased in the absence of sulfate. As much as 87% of 2-[14C]MNAP was mineralized to14CO2. 2-Naphthoic acid (2-NA) was detected as a metabolite, and incubation with either deuterated 2-MNAP or [13C]bicarbonate indicates that 2-NA is the result of oxidation of the methyl group. Also detected were carboxylated 2-MNAPs, suggesting the presence of an alternative pathway for 2-MNAP degradation.

Abstract:

We investigated the possibility of producing porous carbon-mineral materials based on sapropel, and also the variation of their textural characteristics and the chemical state of the surface by acidic, alkaline treatment and processing with water vapor. Prepared carbon-mineral-supported cobalt-molybdenum catalyst tested in the reaction of hydrotransformation of 2,4 – dibenzothiophene and α - methylnaphthalene.

Abstract:

Two new naphthoquinones, 8-[(2′E)-3′,7′-dimethylocta-2′,6′-dienyl]-2,7-dihydroxynaphthalene-1,4-dione (1) and 2-hydroxy-6,7-dimethoxy-3-methylnaphthalene-1,4-dione (2), and one known naphthoquinone, (+)-teretifolione-B (3), were isolated from the roots of Conospermum sphacelatum Hook. (Proteaceae) collected in central Queensland. The structures of compounds (1) and (2) were determined by spectroscopic analysis.
