2-Nitroaniline, also known as ortho-nitroaniline, is a significant chemical compound with a wide range of applications in various industries. As a reliable supplier of 2-Nitroaniline, I am pleased to share detailed information about its physical properties, which can help you better understand this compound and its potential uses.
Appearance and Odor
2-Nitroaniline is an orange to red crystalline solid at room temperature. Its distinct color makes it easily recognizable in laboratory and industrial settings. The compound has a characteristic odor, which is often described as slightly aromatic. However, it's important to note that inhaling the fumes of 2-Nitroaniline can be hazardous, so proper safety precautions should always be taken when handling it.
Melting and Boiling Points
One of the key physical properties of 2-Nitroaniline is its melting point. It melts at approximately 71 - 73 °C (160 - 163 °F). This relatively low melting point allows for easy processing in many chemical reactions where melting is required. The boiling point of 2-Nitroaniline is around 284 °C (543 °F). At this temperature, the compound transitions from a liquid to a gaseous state. Understanding these phase transition temperatures is crucial for applications such as distillation and purification processes.
Solubility
The solubility of 2-Nitroaniline varies depending on the solvent. It is sparingly soluble in water, which means only a small amount can dissolve in water at a given temperature. At 20 °C, the solubility of 2-Nitroaniline in water is about 0.1 g/100 mL. This limited solubility in water can be advantageous in some separation processes, as it allows for easy separation from water-soluble impurities.
On the other hand, 2-Nitroaniline is more soluble in organic solvents. It dissolves readily in ethanol, ether, and chloroform. This solubility in organic solvents makes it suitable for use in organic synthesis reactions, where organic solvents are commonly used as reaction media. For example, in the production of certain dyes and pigments, 2-Nitroaniline can be dissolved in an organic solvent to react with other chemicals to form the desired product.
Density
The density of 2-Nitroaniline is approximately 1.44 g/cm³. This relatively high density is due to the presence of the nitro group (-NO₂) in its molecular structure. The density property is important in processes such as sedimentation and separation. In a mixture where 2-Nitroaniline is present, its higher density can cause it to settle at the bottom, facilitating separation from less dense substances.
Stability
2-Nitroaniline is a relatively stable compound under normal conditions. It does not react readily with air or moisture at room temperature. However, it is sensitive to heat and strong oxidizing agents. When heated to decomposition, it can release toxic fumes, including nitrogen oxides. Therefore, proper storage and handling procedures are essential to ensure its stability and safety. It should be stored in a cool, dry place away from sources of heat and ignition.
Uses Based on Physical Properties
The physical properties of 2-Nitroaniline make it suitable for a variety of applications. In the dye and pigment industry, its solubility in organic solvents and its ability to undergo chemical reactions make it a key intermediate in the synthesis of various dyes. The color of 2-Nitroaniline itself can also contribute to the final color of the dye product.
In the pharmaceutical industry, 2-Nitroaniline can be used as a starting material for the synthesis of certain drugs. Its melting point and solubility properties allow for easy incorporation into chemical reactions to form more complex pharmaceutical compounds.
Comparison with Related Compounds
When comparing 2-Nitroaniline with related compounds such as P-Phenylenediamine (PPD) For Hair Dye, there are some notable differences in physical properties. PPD is a white to light gray powder, which is different from the orange - red crystalline appearance of 2-Nitroaniline. PPD is also more soluble in water compared to 2-Nitroaniline, which affects their respective applications in different industries.
Another related compound is 1 1 Carbonyldiimidazole Cas. 1,1 - Carbonyldiimidazole is a white to off - white crystalline powder with a different melting point and solubility profile compared to 2-Nitroaniline. These differences in physical properties lead to different uses in chemical synthesis.
