M-Cresol → HCID 69990582, compound

Participants

Reaction Steps

Distillation was conducted in the same manner as in Example B2, except that the internal pressure of flask of 1.33×103 Pa was used instead of that of 1.33×104 Pa in Example B2, to thereby obtain about 10 g each of the forerun, middle-run, post-run and bottom. The compositions of 1,3-dimethyl-2-imidazolidinone and m-cresol contained therein were determined in the same manner as in Example B2 to give each the same composition, 1,3-dimethyl-2-imidazolidinone/m-cresol=51.35% by weight/48.65% by weight (1:1 by molar ratio), that is, no difference in compositions thereof was found.
