  • Purification of solvents used for the purification of alkylene oxide
    Patent number: 7182841
    Abstract: This invention concerns a process for removing carbonyl-containing impurities from impure extractive distillation solvent such as a glycol, comprising: contacting the impure extractive distillation solvent with an acidic ion exchange resin. The purified extractive distillation solvent can be recycled for use as a solvent in an extractive distillation process that removes impurities from alkylene oxide. The extractive distillation solvent can be ethylene glycol monomethyl ether (EGME) used to purify propylene oxide.
    Type: Grant
