o-Nitroaniliini eli 2-nitroaniliini (C6H6N2O2) on nitroryhmän sisältävä orgaaninen yhdiste ja aniliinin johdannainen. Yhdistettä käytetään orgaanisessa synteesissä valmistettaessa väriaineita ja muita kemikaaleja. o-Nitroaniliinista käytetään myös nimiä 2-nitroaminobentseeni ja 1-amino-2-nitrobentseeni. Kiinteänä aine on väriltään oranssia. o-Nitroaniliini on m-nitroaniliinin ja p-nitroaniliinin isomeeri.

Valmistus

o-Nitroaniliinia valmistetaan yleensä teollisesti o-kloorinitrobentseenin ammonolyysillä eli reaktiolla väkevän ammoniakkiliuoksen kanssa. Reaktio tapahtuu 4MPa:n paineessa ja lämpötila kohotetaan vähitellen 180 °C asti. Reaktio on hyvin eksoterminen ja liiallinen lämmitys voi johtaa hallitsemattomaan reaktioon.[4]

Yhdistettä voidaan valmistaa myös lähtemällä asetanilidista, jolloin muodostuu myös p-nitroaniliinia, tai 2-nitroaniliini-4-sulfonihaposta.[2]

Käyttö

Suurin osa o-nitroaniliinista käytetään o-fenyleenidiamiinin valmistukseen raudan tai vedyn avulla pelkistämällä. Ainetta käytetään myös atsovärien ja vat-väriaineiden sekä 2-aminoasetanilidin valmistamiseen.[2][4]
