The present invention provides an ethyl-2-cyanoacrylate adhesive composition obtained as a result of significant improvement on conventional problems, that is, irritating odor and whitening of conventional ethyl-2-cyanoacrylate adhesive compositions. According to a method of the present invention for purifying an ethyl-2-cyanoacrylate adhesive composition, a sum total of an acrylonitrile content and an ethanol content is arranged to be in a range of 1 ppm to 150 ppm, by carrying out deaeration at the same time as injection of an inactive gas at a reduced pressure in a range of 100 Pa to 10000 Pa at a temperature in a range of 5° C. to 50° C. Thereby, the method of the present invention allows improving irritating odor and whitening. |
