Synthesis method
By O-nitrotoluene is obtained by chlorination and reduction. 1.Chlorinated in o-nitrotoluene , add 2% Iron acts as a catalyst in50-60℃ Pour in chlorine until the relative density of the reaction solution reaches1.27-1.29（50℃) Until now, use 5% Hydrochloric acid washing, and then Wash with water, and finally adjust the pH with liquid alkalipH for7. Separate the water layer, evaporate the water, and conduct vacuum distillation to collect120-150℃（) fraction, cool, crystallize and filter to obtain2-chlorine-6-Nitrotoluene. 2.Reduction Add hydrochloric acid and iron powder Stir and heat in the reaction pot until 90℃ , slowly add the melted2-Chlorine -6-Nitrotoluene, added , reflux reaction3h. Cool, add liquid alkali to adjustpH is8, steam distilled, get 3-Chloro-o-toluidine.
Purpose
