Procedure
A reactor was charged with γ-butyrolactone, 2-aminoethanol and water, to produce N-(2-hydroxyethyl)-2-pyrrolidone. The molar ratio of the 2-aminoethanol/γ-butyrolactone was 1.0, and that of the γ-butyrolactone/water was 1.1. The reaction temperature was 250° C. and the reaction time was 2 hours.
