Procedure

Distillation was conducted in the same manner as in Example A2 except that the internal pressure of flask of 1.33×103 Pa was used instead of that of 1.33×104 Pa in Example A2, to thereby obtain about 10 g each of the forerun, middle-run, post-run and bottom. The compositions of N-methyl-2-pyrrolidone and m-cresol contained therein were determined in the same manner as in Example A2 to give each the same composition, N-methyl-2-pyrrolidone/m-cresol=47.8% by weight/52.2% by weight (1:1 by molar ratio), that is, no difference in compositions thereof was found.
