2-Methyl-4-nitroaniline Chemical Properties,Uses,Production
Chemical Properties
Yellowneedle
Uses
2-Methyl-4-nitroaniline was used in preparing in-plane aligned nanofibers by the electrospinning technique. It was the starting reagent in the synthesis of 3-chloro-5-methylphenyl isocyanate. It was used to deposit polycrystalline thin films on Ag, Cu and Si by conventional and partially ionized beam deposition.
Production Methods
N-Benzenesulfonyl-o-toluidine is dissolved in chlorobenzene at 40 – 50 ℃, and 62 % nitric acid is added gradually to give 5- nitro-N-benzenesulfonyl-o-toluidine, which is isolated and hydrolyzed in sulfuric acid to give 5-nitro-o-toluidine in 80 % yield.
General Description
Yellow needles or mustard yellow powder.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
2-Methyl-4-nitroaniline is incompatible with acids, acid chlorides, acid anhydrides, chloroformates and strong oxidizing agents.
Fire Hazard
Flash point data for 2-Methyl-4-nitroaniline are not available; however, 2-Methyl-4-nitroaniline is probably combustible.
Purification Methods
Crystallise the nitrotoluidine from EtOH. The acetyl and benzoyl derivatives have m 200o and 174o (EtOH) respectively. [Beilstein 12 IV 1809.]
