Background: Naphthalene exposures for most non-occupationally exposed individuals occur primarily indoors at home. Residential indoor sources include pest control products (specifically moth balls), incomplete combustion such as cigarette smoke, woodstoves and cooking, some consumer and building products, and emissions from gasoline sources found in attached garages. The study aim was to assess...
To test the hypothesis that o-hydroxy amines are proximate agents in chemical carcinogenesis paraffin pellets containing the hydrochlorides of 2-amino-l-fluorenol, 2-amino-3-fluorenol, 2-amino-5-fluorenol, 2-amino-7-fluorenol, 2-fluorenamine, and 1amino-2-naphthol were implanted into the urinary bladders of Swiss female mice. Paraffin pellets alone were implanted as controls. Histological exami...
Naphthalene and 2-naphthol are two naphthalene derivatives, which play important roles in the chemical and pharmaceutical industries. The aim of this study was to evaluate the impact of biofield energy treatment on the isotopic abundance of 13 C/ 12 C or 2 H/ 1 H and 18 O/ 16 O in naphthalene and 2-naphthol using gas chromatography-mass spectrometry (GCMS). Naphthalene and 2-naphthol samples we...
In the title compound, C(24)H(18)N(2)O(4), the phenyl and benzene rings are both oriented almost perpendicular to the naphthalene ring system at dihedral angles of 70.97 (5) and 84.64 (5)°. The former rings make a dihedral angle of 87.15 (6)°. The mol-ecule has a Z configuration about the C=N bond. In the crystal, mol-ecules are connected by a pair of inter-molecular O-H⋯O hydrogen bonds betwee...
In the title compound, C(10)H(9)NO, the amino and the hydr-oxy groups act both as a single donor and a single acceptor in hydrogen bonding. In the crystal, mol-ecules are connected via chains of inter-molecular ⋯N-H⋯O-H⋯ inter-actions, forming a two-dimensional polymeric structure resembling the hydrogen-bonded mol-ecular assembly found in the crystal structure of naphthalene-1,5-diol. Within t...
A room-temperature phosphorimetric (RTP) study of the inclusion process between 1- and 2-naphthol, beta-cyclodextrin (beta-CD) and 3-bromo-1-propanol as heavy atom pertuber has been performed. Experimental conditions were optimized for the formation of trimolecular complexes with lifetimes of 10.82 and 9.41 ms for 1- and 2-naphthol, respectively. A synchronous-derivative room-temperature phosph...
Benzo[b]cyclohexa-2,4-dien-1-one (4) and benzo[b]cyclohexa-2,5-dien-1-one (5), the two most stable keto tautomers of 1-naphthol (1), were generated in aqueous solution by Norrish Type II fission of 4- and 2-phenacyl-1-tetralone, respectively, and the pH-rate profiles of their enolization were measured by flash photolysis. Several isotopic exchange rates of 1 were measured in aqueous acid to det...
