O-nitrotoluene by chlorination, reduction derived.
1. Chlorination In o-nitrotoluene, add 2% ferric chloride as a catalyst, pass chlorine gas at 50-60°C, until the relative density of the reaction solution reaches 1.27-1.29 (50°C), use 5% It was washed with hydrochloric acid, washed with water, and finally adjusted to pH 7 with a caustic soda. Divide the water layer and evaporate the water, then vacuum distillation, collecting 120-150 ° C (5.33-8.0kPa) fractions, cooling and crystallization, filtration, 2-chloro-6-nitrotoluene.
2. Reduction Add hydrochloric acid and iron powder to the reaction kettle with stirring and heating until 90°C. Slowly add the melted 2-chloro-6-nitrotoluene, complete the addition, and reflux for 3 hours. Cool, add alkali to adjust the pH to 8, steam distillation to give 3-chloro-o-toluidine.
It is an important raw material for synthetic dyes and pesticides. It can synthesize dye DB-50, and can produce herbicides for paddy fields to kill crickets.
