Ningbo Inno Pharmchem Co., Ltd. provides aniline oil, a cornerstone chemical in numerous industrial processes. Understanding its fundamental chemical properties is key to appreciating its broad utility and the critical role it plays across various manufacturing sectors.

Aniline, with the chemical formula C6H5NH2, is the simplest aromatic amine. It is characterized by a phenyl group attached to an amino group. Physically, pure aniline is a colorless to pale yellow oily liquid that can darken upon exposure to air and light due to oxidation. It has a distinctive odor often described as resembling rotten fish, and it ignites readily, burning with a characteristic smoky flame of aromatic compounds. Key physical properties include a density of approximately 1.022 g/cm³, a boiling point of 184.4 °C, and a melting point of -6.2 °C. Its solubility in water is moderate, around 36 g/L at 20 °C, but it is miscible with many organic solvents, making it adaptable to various reaction mediums. These properties, combined with its reactive amino group and aromatic ring, make aniline oil an exceptionally versatile intermediate for chemical synthesis.

The industrial significance of aniline oil cannot be overstated. Its primary applications include the production of methylene diphenyl diisocyanate (MDI) for polyurethanes, a vast array of dyes and pigments, and chemicals used in rubber processing. Furthermore, it is a vital intermediate in the synthesis of pharmaceuticals, such as paracetamol, and is extensively used in the production of agrochemicals like pesticides and herbicides. The demand for aniline oil is closely tied to the performance of these major industries, which constantly require this fundamental building block. Ningbo Inno Pharmchem Co., Ltd. is dedicated to supplying high-purity aniline oil that meets the stringent quality requirements of these diverse applications, ensuring reliable and efficient chemical synthesis for our partners.
