I started preparation morpholine dehydration diethanolamine by starting materials: diethanolamine (1mol), H2SO4 (1.8 mol). Temperature (200 oC). After 1o h the acidic solution neutralized with NaOH 50 % . What can I do next step purification morpholine from aqueous soultion?

As morpholine is water soluble it remains in aqueous solution.you have to saturate the solution with NaOH solid flakes .when solution become supersaturated,separate layers of morpholine might be separated.if not you can extract with solvent like cyclohexane,distillation of solvent gives you crude Morpholine which can be purified by distillation.
