Uses and applications

What the substance is used for, by industry and function

Color test for pine wood.

3-Nitroaniline is used as a diazo component (Fast Orange R Base) in azo dyes (e.g., C.I. Disperse Yellow 5 and C.I. Acid Orange 18).

Used as dye intermediate.

How it is made

Partial reduction of 1,3-dinitrobenzene with sodium sulfide.

From aniline by nitration after acetylation, with subsequent removal of acetyl group by hydrolysis, from m-nitrobenzoic acid.

1,3-Dinitrobenzene is added to warm water containing magnesium sulfate. An aqueous solution of sodium hydrogen sulfide (6 molar equivalents) is added gradually to the vigorously stirred emulsion, and reduction is completed by heating to 90 °C. The 3-nitroaniline produced solidifies on cooling and is separated by filtration.
