Identification of derivatives of bisphenol A diglycidyl ether and novolac glycidyl ether in can coatings by liquid chromatography/ion trap mass spectrometry.
A reversed-phase liquid chromatographic method combined with fluorescence and multiple mass spectrometric detection in series is presented for the separation and structure elucidation of bisphenol A diglycidyl ether (BADGE) and novolac glycidyl ether (NOGE) derivatives. Atmospheric pressure chemical ionization in the positive ion mode and collision induced fragmentation in the ion trap allowed ...
متن کاملStability of bisphenol A diglycidyl ether and bisphenol F diglycidyl ether in water-based food simulants
Varnishes used for the inner coatings of food cans are often based on epoxy resins or vinylic organosols. The epoxy resins can be produced from bisphenol A (BPA) and bisphenol F (BPF), and these also contain bisphenol A diglycidyl ether (BADGE) or bisphenol F diglycidyl ether (BFDGE) as stabilising components. These compounds may break down during storage and also by the influence of food simul...
متن کاملSimilar dielectric behaviour of polyphenylglycidyl-ether and diglycidyl-ether of bisphenol-A at glass transition temperature
In this work, the dynamics of the primary and the Johari-Goldstein (JG) processes are studied with dielectric spectroscopy. We found the relaxations at glass transition temperature in polyphenylglycidylether and diglycidyl ether of bisphenol-A to be strongly correlated over a wide temperature T and pressure P range. Analysing the temperature and pressure behaviour of the and (JG) -processes...
متن کاملBisphenol A diglycidyl ether as a potential metabolic source of bisphenol A.
Epoxy resins find widespread use as adhesives and coatings in the construction and food industries. The majority of the products are based on resins that use bisphenol A diglycidyl ether (BADGE) as a precursor. This raises the question if BADGE could be a potential source of bisphenol A (BPA). The recent paper by Perez et al. (1) on the estrogenicity of BPA and some of its analogs and derivativ...
متن کاملspecific migration of bisphenol-a diglycidyl ether (badge) and its derivatives in four different temperatures in epoxy lacquer
migration of compounds from packaging materials is one of the most important aspects of food safety. epoxy resins have been in inner coatings of food cans since the 1960s. these resins can be produced from bisphenol-a diglycidyl ether (badge) that is also utilized as a starter. migration of potentially toxic compounds in epoxy resins used for commercial cans is a very important food safety issu...
