Patent ID: 8716502

Claim:
A process for manufacturing at least one divinylarene oxide comprising the steps of: (a) reacting (i) at least one divinylarene with (ii) at least one peroxycarboximidic acid epoxidizing agent in the presence of (iii) at least one solvent and (iv) at least one basic compound, to form a reaction effluent comprising at least one divinylarene oxide and at least one amide; (b) evaporating at least a portion of at least one lights from the reaction effluent of step (a) at a temperature and pressure sufficient to form a biphasic liquid concentrate comprising (b1) an organic phase containing at least a portion of the at least one divinylarene oxide and (b2) an aqueous phase; and at a temperature and pressure sufficient to minimize the thermal degradation or hydrolysis of the at least one divinylarene oxide; and (c) separating the organic phase containing the at least one divinylarene oxide from the aqueous phase.
