Two-stage steam explosion pretreatment of softwood with 2-naphthol as carbocation scavenger
Background Lignocellulosic biomass is considered as a potential source for sustainable biofuels. In the conversion process, a pretreatment step is necessary in order to overcome the biomass recalcitrance and allow for sufficient fermentable sugar yields

A wave-mechanical treatment of the Mills-Nixon effect [PDF]
The Mills-Nixon effect has been examined by a very simple wave-mechanical treatment. This has led to the conclusion that the effect of saturated side rings upon the ratio of the coefficients of the wave-functions of the two Kekulé structures is ...

Cyclization of hydrazones derived from 2-acetyl-1-naphthol and 1-acetyl-2-naphthol with triphosgene gave naphtho[1,2-e]-1,3-oxazines, naphtho[2,1-e]-1,3-oxazines or their spiro dimers depending on the molar ratio of triphosgene used for the cyclization.

Reactions of cyclobutenones with nucleophilic reagents via vinylketen intermediates [PDF]
While strong nucleophiles add to the endocyclic double bond of cyclobutenones to yield cyclobutanones, weaker nucleophiles (e.g. alcohols, aniline) interact with the vinylketens which are thermally or photochemically generated from cyclobutenones; the ...

High-Performance Liquid Chromatographic Determination of Naphtholsulfonic Acids
A HPLC-method for the quantitative analysis of mixed solutions of 2-naphthol-5,7-disulfonic acid and 2-naphthol-7-sulfonic acid was developed. A complete reproducible separation of these compounds in a very short time could be reached by using a ...

Alumina growth narrows surface pores and seals non‐selective defects, enhancing selectivity while preserving the nanoporous graphene architecture. Additionally, the deposition enables gradient‐controlled structural modification, with intergrown alumina acting as a physical cross‐linker that stabilizes the laminar structure.

Acid Catalyzed Formation of C–C and C–S Bonds via Excited State Proton Transfer
The behavior of 2-naphthol and 7-bromo-2-naphthol as organic photoacids are exploited in organic synthesis for the preparation of benzyl sulfides (using a trichloroacetimidate derivative as the starting substrate) and polycyclic amines via acid catalyzed

In the title compound, C(10)H(6)N(2)O(5), the two fused rings are almost co-planar, with an r.m.s. deviation of 0.0163 Å. The nitro groups are oriented at dihedral angles of 2.62 (11) and 44.69 (11)° with respect to the plane of the parent fused rings. Intra-molecular O-H⋯O and C-H⋯O hydrogen bonds complete S(6) ring motifs.
