The aim of the research was to develop a method for identification of compounds emitted during thermal degradation of binders used in foundry. Research were performed with the use of Certified Reference Materials mixtures of semi-volatiles compounds with furfuryl alcohol and aldehyde. Furfuryl-urea resin samples were also used. Station for thermal degradation of materials used in foundry was designed and made. Thermal degradation process conditions and gas chromatograph coupled with high resolution mass spectrometry operating conditions were established. Organic compounds emitted during degradation were identified. The paper briefly represents the range of study and the results obtained for furfuryl-urea resin thermal degradation. Significant information about volatile and semi-volatile organic compounds emitted in different temperatures is also discussed.
