Abstract: THE PROCESS FOR THE PRODUCTION OF BIS-HYDROXYALKYL PHTHALATES BY REACTING AN ALKYLENE OXIDE WITH A BENZENE DICARBOXYLIC ACID IN THE PRESENCE OF A CATALYST AND IN A NITROBENZENE OR NITROTOLUENE REACTION MEDIUM. FOR EXAMPLE ETHYLENE OXIDE IS REACTED WITH TEREPHTHALIC ACID IN A NITROBENZENE REACTION MEDIUM USING A TERTIARY AMINE CATALYST SO AS TO PRODUCE BIS(2-HYDROXYETHYL) TEREPHTHALATE.

Abstract: PROCESS FOR THE PRODUCTON OF BIS-HYDROXYALKYL PHTHALATES BY REACTING AN ALKYLEN OXIDE WITH A BENZENE DICARBOXYLIC ACID IN THE PRESENCE OF A CATALYST AND IN AN ALKYLSUBSTITUTED DIOXOLENE REACTION MEDIUM. FOR EXAMPLE ETHLENE OXIDE IS REACTED WITH TEREPHTHALIC ACID IN A 2ETHYL, 2-METHYL DIOXOLANE REACTION MEDIUM USING A TERTIARY AMINE CATALYST SO AS TO PRODUCE BIS(2-HYDROXYENTHYL) TEREPHTAHALATE.
