Title: Separation of high-boiling substance from reaction mixture produced in diaminotoluene production
Inventor: HEIKO BETSUKUHAUSU
IPC: C07C209/84
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To provide a method for treating an amine mixture produced in the production of diaminotoluenes by hydrogenating dinitroaromatic compounds in order to separate high-boiling substances from a desired amine product.  
     SOLUTION: First, reaction water and a solvent are removed from a diaminotoluene isomer mixture (TDA mixture) followed by separating low- boiling TDA isomers by use of a TDA isomer distillation column. The bottom phase left after the 1st distillation comprises a mixture of m-TDA 4 and high- boiling substances. The bottom phase 3 is separated and concentrated until the high-boiling substance content comes to about 25-60wt.%. Subsequently, the concentrated bottom phase is mixed with o-TDA in the weight ratio of (1:1) to (1:5), and the resultant m-/o-TDA mixture is removed by distillation. Finally, the m-/o-TDA mixture thus recovered is returned to the TDA isomer distillation column.
