A system, comprising:
- a reactor configured to produce a product stream in the presence of dehydration agent,
- wherein the reactor comprises:
- an inlet configured to receive a hydroxypropanamide stream comprising a hydroxypropanamide, and solvent;
- an outlet configured to output the product stream;
- and
- a multitemperature stage column having a zone comprising TiO2 and separately, a zone comprising SiO2;
- wherein the product stream comprises the unsaturated amide and/or the unsaturated nitrile, or isomers thereof and the solvent.
