  • PROCESS FOR REMOVING METHOXYETHANOL FROM A MIXTURE COMPRISING METHOXYETHANOL AND MORPHOLINE
    Publication number: 20210016204
    Abstract: A method for removing methoxyethanol from a mixture comprising methoxyethanol and morpholine makes use of the selective adsorption of methoxyethanol onto a mixed oxide comprising a spinel phase. The mixed oxide comprises 20 to 30% by weight MgO and 80 to 70% by weight Al2O3. The spinel phase has the formula MgAl2O4. The mixture is a pre-purified reaction output of the reaction of diethylene glycol with ammonia in the presence of an amination catalyst.
