Aniline plays a crucial role in the dye industry and serves as a fundamental component for numerous azo dyes. It is extensively utilized in the synthesis of various intermediates such as acetanilide, acetoacetanilide, aminoazobenzene, methyl aniline, diethyl aniline, and more.

When recently distilled, the substance should exhibit as a clear oily liquid, ranging from colorless to pale yellow, with a distinctive strong aroma. However, over time, it tends to darken during storage. Adherence to the standards outlined is essential for this material. It's imperative to maintain a well-equipped laboratory for conducting the specified tests according to the methods outlined in the standard.

TESTS

The subsequent test must be conducted for Aniline technical.

• Relative density

• Crystallizing Point

• Distillation range

• Assay

• Nitrobenzene content by GC

• Moisture content

PACKING AND MARKING

Packing and marking procedures need to comply with IS 2833:2019 standards. The material should be packed in suitable drums, ensuring each container is securely sealed and labeled with the required information as per the standard. The product's container should bear the Standard Mark (ISI Mark) only if the material meets the specified requirements. To utilize the standard mark (ISI Mark), manufacturers must obtain a BIS license from the Bureau of Indian Standards, which involves an evaluation of manufacturing infrastructure, quality control, testing capabilities, and production processes.
