Aromatic compounds in waste gases formed during thermal decomposition of foundry binders


The paper presents the results of analysis of gases formed under the impact of high temperature acting on moulding sands with the addition of selected organic resins and hardeners, commonly used in foundries as binders for these sands. As a research tool, a dedicated gas chromatograph, designed to identify specifically aromatic compounds from the group of alkanes, was applied.
