A process for recovering a divinylarene dioxide from a crude feed stream comprising the steps of: (a) providing an effluent reaction stream containing at least one divinylarene dioxide product and other compounds; and (b) separating/recovering the divinylarene dioxide product from the other compounds of the reaction effluent from step (a); wherein the percent recovery of the divinylarene dioxide product recovered comprises greater than about 85 percent; and wherein the percent purity of the divinylarene dioxide product recovered comprises greater than about 85 percent.

Process for recovering divinylarene dioxides

Use a modified, amine-functionalized anion exchange resin as a catalyst to produce a bishalohydrin ether and then dehydrohalogenate the bishalohydrin ether with an aqueous inorganic hydroxide mixture to yield a liquid epoxy resin.

Production of epoxy resins using improved ion exchange resin catalysts

A process for preparing a divinylarene oxide including (a) reacting (i) at least one divinylarene; (ii) at least one peroxycarboximidic acid; (iii) at least one solvent; and (iv) at least one basic compound, under reaction conditions to form a reaction effluent containing a divinylarene oxide product; and then (b) evaporating the reaction effluent of step (a) to form a concentrate containing the divinylarene oxide product; and wherein the concentrate separates into two liquid phases.
