2-Methyl-4-nitroaniline Chemical Properties,Usage,Production

Description

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.

Chemical Properties

Yellowneedle

Uses

A red azoic dye.

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.]
