Abstract
The study of the chemical composition of water formed during pyrolysis of waste tyres was made. The obtained pyrolytic water was characterized by FT-IR techniques, gas chromatography-mass spectrometry, dissociation extraction and a distribution chromatography method. It was found out that pyrolytic water consists of about 93 compounds, from which 27 compounds were identified by GC-MS method. Quantitative analysis established that total content of compounds is up 0,90 g/dm3, from which caprolactam – 46 %, cyclohexanone – 5, aniline – 17, benzonitrile – 6, о-cresol – 2,6, p-cresol – 2,8, benzothyazole – 4,9, 2,4-dimethylquinoline – 4,6, phthalimide – 2,5 %. By dissociative extraction of organic acids and bases it was shown that peaks of some components of chromatogram contain minor components. Distribution coefficients in hexane-water system of cyclohexanone, aniline, benzonitrile, о-cresol, p-cresol, 2,5-dimethylphenol, benzoic acid, benzothyazole, caprolactam, 1-methyl-isoquinoline, 2,4-dimethylquinoline and phthalimide were defined.
