Abstract: The invention relates to a process for distillatively preparing TDA from a reactant stream comprising TDA, high boilers and low boilers in a dividing wall column in which a dividing wall is disposed in the longitudinal direction of the column to form an upper combined column region ( 2 ), a lower combined column region ( 3 ), a feed section ( 4 ) having a rectifying section ( 5 ) and stripping section ( 6 ), and also a withdrawal section ( 7 ) having a rectifying section ( 9 ) and stripping section ( 8 ), which comprises the following steps: a. feeding the reactant stream ( 13 ) into the feed section ( 4 ) of the dividing wall column ( 1 ); b. drawing off a low boiler fraction via the top of the column ( 11 ); c. drawing off TDA via a side draw ( 14 ) in the withdrawal section ( 7 ) of the dividing wall column ( 1 ); d. drawing off a low boiler fraction via the bottom of the column ( 12 ).
