| | 2-メチル-4-ニトロアニリン Usage And Synthesis |
| 外観 | 黄色～黄褐色, 結晶性粉末～粉末 | | 溶解性 | 水に難溶, エタノール, アセトンに可溶。エタノール及びアセトンに溶けやすく、水にほとんど溶けない。 | | 用途 | 有機合成原料。 | | 用途 | 染料、ジアゾ感光剤の中間体、顔料の中間体。 | | 化学的特性 | Yellowneedle | | 使用 | A red azoic dye. | | 使用 | 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. | | 調製方法 | 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. | | 一般的な説明 | Yellow needles or mustard yellow powder. | | 空気と水の反応 | Insoluble in water. | | 反応プロフィール | 2-Methyl-4-nitroaniline is incompatible with acids, acid chlorides, acid anhydrides, chloroformates and strong oxidizing agents. | | 火災危険 | Flash point data for 2-Methyl-4-nitroaniline are not available; however, 2-Methyl-4-nitroaniline is probably combustible. | | 純化方法 | Crystallise the nitrotoluidine from EtOH. The acetyl and benzoyl derivatives have m 200o and 174o (EtOH) respectively. [Beilstein 12 IV 1809.] |
