CARAMAO, Elina Bastos  and  NASCIMENTO FILHO, Irajá do. Quantitative analysis of phenol and alkylphenols in Brazilian coal tar. Quím. Nova [online]. 2004, vol.27, n.2, pp.193-195. ISSN 0100-4042.

The main purpose of this work is the identification and quantification of phenolic compounds in coal tar samples from a ceramics factory in Cocal (SC), Brazil. The samples were subjected to preparative scale liquid chromatography, using Amberlyst A-27TM ion-exchange resin as stationary phase. The fractions obtained were classified as "acids" and "BN" (bases and neutrals). The identification and quantification of phenols, in the acid fraction, was made by gas chromatography coupled to mass spectrometry (GC/MS). Nearly twenty-five phenols were identified in the samples and nine of them were also quantified. The results showed that coal tar has large quantities of phenolic compounds of industrial interest.

Keywords : coal tar; phenols; GC/MS.
