Abstract
Polyglycidyl compounds are prepared by reacting certain polyallyl compounds with a percarboxylic acid containing 3 or 4 C atoms, subsequently removing, by distillation, the carboxylic acid formed from the percarboxylic acid, then separating the remaining mixture by simultaneous extraction with a lipophilic and a hydrophilic phase, subsequently working up the laden lipophilic phase and the laden hydrophilic phase separately in a manner which is known per se, and obtaining the polyglycidyl compound as the residue from working up of the laden hydrophilic phase.
