Paragraph 0014, (2017/07/19)
A process for preparing 3, 4, 5 - toluene azeotrope by-product of the 2, 4, 5 - method for comprehensive utilization of toluene azeotrope, which belongs to the field of chemical synthesis. In order to 2, 4, 5 - trifluoro toluene as the raw materials, the aminolysis reaction, catalytic hydrogenation dechlorination reaction, the chlorination reaction to synthesize 2, 6 - dichloro - 4 - trifluoromethyl aniline. The above-mentioned integrated utilization method, the useless by-product into higher economic value products, the overall yield 61.7%, purity of 99.5% or more, less impurity species, product quality and stable performance.
