STUDY ON EMISSION OF DECOMPOSED CHEMICALS OF ESTERS CONTAINED IN PVC FLOORING AND ADHESIVE

Recently, products of chemical reaction have been at issue as the topic of research on Indoor AirQuality. In this study, the emission mechanism of 2-ethyl-1-hexanol (2E1H) is studied. It has beenreported that 2E1H at high concentrations is measured in indoor air over the long term. The emissionmechanism for 2E1H is considered that water with high pH in concrete slabs and self-leveling sub-floormaterial reacts to di-2-ethylhexyl phthalate (DEHP) in PVC flooring and compounds containing the2-ethyl-1-hexyl group in the adhesive.
