The title compound, C(26)H(25)NO, was obtained via a one-pot synthesis from the reaction of 2-naphthol, 1-(p-tol-yl)ethyl-amine, p-toluene-sulfonic acid and benzaldehyde. There are three mol-ecules per asymmetric unit, all having similar conformations. There are intra-molecular O-H⋯N and C-H⋯O hydrogen bonds, with only van der Waals forces found between mol-ecules.
The title compound, C(22)H(18)N(2)O, was synthesized from naphthalen-2-ol, benzaldehyde and pyridin-2-amine. In the crystal, mol-ecules are linked into centrosymmetric R(2) (2)(16) dimers by pairs of O-H⋯N hydrogen bonds. The mol-ecular conformation is stabilized by an N-H⋯O hydrogen bond. The dihedral angle between the naphthylene ring system and the phenyl ring is 72.86 (12)°.
In the title compound, C(23)H(25)NO, the dihedral angle between the naphthyl-ene ring system and the benzene ring is 78.17 (10)°. The mol-ecular conformation is stabilized by a strong intra-molecular O-H⋯N hydrogen bond.
Abstract The use of chemical additives (1- and 2-naphthol, formaldehyde) in hydrothermal pre-treatments pine, birch, willow wood was evaluated to minimize lignin condensation reactions consequently improve the saccharification pre-treated materials. residual hydrolysis lignins were then tested preparation polylactic acid (PLA)-based composites. results showed that addition 2-naphthol pre-treatm...
Ionic liquid (IL) based dispersive liquid-liquid microextraction (DLLME) with back-extraction coupled with capillary electrophoresis ultraviolet detection was developed to determine four phenolic compounds (bisphenol-A, β-naphthol, α-naphthol, 2, 4-dichlorophenol) in aqueous cosmetics. The developed method was used to preconcentrate and clean up the four phenolic compounds including two steps. ...
