反応手順
After the pressure drop (column 1: approx. 45 mbar, column 2: approx. 25 mbar) und the temperature profile (73-77° C.) had stabilized, m-xylidine (16.9 kg/h) was fed to the 2nd plate and diketene (total 12.0 kg/h) to plate Nos. 14, 15 and 16 of the first column. The diketene feed was started only after the xylidine-containing reflux had reached plate No. 14.
