摘要

The main purpose of this work is the identification and quantification of phenolic compounds in coal tar samples of a ceramic industry from Cocal (SC-BR). The samples were subjected to liquid chromatography in preparative scale, using ion exchange resin Amberlyst A-27tm as stationary phase. The fractions obtained were classified as "acids" and "BN" (bases and neutrals). The identification and quantification of phenols was made by gas chromatography coupled with mass spectrometry and gas chromatography with flame ionization detection (GC/MS & GC/FID). It was identified near twenty five phenols 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.
