Dihydrodihydroxy compounds are important intermediates in the metabolic pathways of aromatic hydrocarbons, giving rise to many of the metabolites observed in the urine when the parent hydrocarbons are given to animals. Thus, for example, when tran8-1,2-dihydro-1,2-dihydroxynaphthalene is given to rats it is excreted partly unchanged in conjugation with glucuronic acid, partly as 1-naphthol in c...

Naphthol isomers were simultaneously and spectrophotometrically determined in wastewater, using a model based on net analyte signal (NAS). The calibration method used is a variation of the original hybrid linear analysis method as proposed by Goicoechea and Olivieri (HLA/GO). Owing to spectral interferences, the simultaneous determination of mixtures of naphthol isomers, using a spectrophotomet...

a convenient and efficient procedure for the synthesis of 14-aryl or alkyl-14h-dibenzo[a,j]xanthenes by condensation of 2-naphthol and aldehydes in the presence of methylimidazolium hydrogensulfate, as a brönsted acidic ionic liquid ([hmim]hso4), is described. both aromatic and aliphatic aldehydes reactedeasily to afford the corresponding 14-aryl or alkyl-14h-dibenzo[a,j]xanthenes in good yield...
