Abstract: N′,N-bis (2-hydroxyethyl) oxamide was prepared from diethyl oxalate and monoethanolamine in the presence of methanol as solvent.The structure of product was characterized by FT-IR.The effects of solvent amount,reaction temperature and holding time,reactant ratio on the yield were discussed.The results showed that optimum conditions for reaction were obtained:methanol as solvent,mass ratio of methanol to diethyl oxalate=5∶1;molar ratio of diethyl oxalate to monoethanolamine=1∶2.3;reaction temperature=70℃,holding time 1.5h.The yield was 97.1%.
