The ethoxylated butoxyethanol-bisphenol A diglycidyl ether adducts were identified in the acetonitrile extracts of can-coating materials, a previously undetected compound in epoxy resin can-coatings.
The acetonitrile extracts of can-coating materials have been analyzed by using high-pressure liquid chromatography/electrospray ionization-mass spectrometry (HPLC/ESI-MS). On the basis of detected ions [M + H](+), [M + NH4](+), [M + Na](+) and product ions, the ethoxylated butoxyethanol-bisphenol A diglycidyl ether adducts were identified in two of the analyzed extracts. Although the oxyethylene unit-containing compounds are widely used for the production of different kinds of materials, the ethoxylated species have not been earlier detected in epoxy resin can-coatings.
