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.

In particular, a process is related for the conversion of glycerin, in particular glycerin from renewable sources, to propanols, the process including the following steps:
(a) hydrogenating a glycerin phase with a Co—Cu—Mn—Mo based hydrogenation catalyst to give an effluent containing water and an organic mixture of more than 40 wt % of a mixture of ethanol, 1-propanol and 2-propanol and the rest being unreacted propanediols and glycerin, with traces of ethylene glycol;
(b) separating by mainly distillation the ethanol, 1-propanol and 2-propanol mixture from the other components in the effluent of step a); and (c)
