The 2-cyanoacrylate-purifying method includes the steps of: (a) adding a specific polyhydric aromatic compound to the 2-cyanoacrylate which has been colored; and (b) storing, at a temperature in a range of 0� C. to 40� C. for 0.5 day or more, the resulting mixture obtained in the step (a), and then subjecting the mixture to reduced pressure distillation. |
