storage method

this product is sealed and stored in a cool, dry place.

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

organic synthesis intermediates.
