[Determination of residual monomers of epoxy resins in wine simulants]

Wine is widely stocked in epoxy resin vats. These bisphenol A epoxy resins are cured with methylenedianiline hardener. The residual monomers are able to migrate through the polymer matrix into the wine. So, migration studies were undertaken in order to prevent human health hazard. In this paper specific chromatographic methods for the determination of the residual monomers in simulants of wine are described. Liquid chromatographic methods were developed for the determination of methylenedianiline and bisphenol A, and a gas chromatographic method for the determination of epichlorhydrin. The procedures described proved to be sensitive, reproducible and efficient.
