Bisphenol A diglycidyl ether → HCID 131731082, compound

Participants

Reaction Conditions

Reaction Steps

20.0 g (approx. 116 mmol epoxy groups) of distilled bisphenol A diglycidyl ether (Epilox A 17-01), 10.0 g (113.5 mmol) of N,N-dimethylurea, and 40 mL ethanol were added to a 250 mL two-necked flask with a reflux condenser. It was refluxed for 7 h at 90° C.; only traces of N,N-dimethylurea were still detectable toward the end of the reaction. After the solvent had been driven off at 60° C. on the rotary evaporator, approx. 30 g of a highly viscous, partially waxy material with a “urea equivalent weight” of approx. 258 g/eq was obtained.
