💡 Commercial Applications
m-Phenylenediamine, also known as 1,3-Diaminobenzene, has various commercial and industrial applications. It is primarily used in the production of polymers, including aramid fibers, which are known for their high strength and heat resistance. m-Phenylenediamine is also used in the manufacturing of hair dyes, rubber chemicals, and antioxidants.
In the realm of drug and medication applications, m-Phenylenediamine is utilized as a component in hair dyes and temporary tattoos. However, it is important to note that m-Phenylenediamine has been associated with allergic reactions in some individuals; therefore, its use in these products is carefully regulated. In the pharmaceutical industry, m-Phenylenediamine is not commonly used due to its potential for skin sensitization and other adverse effects.
⚗️ Chemical & Physical Properties
m-Phenylenediamine is a white to light pink crystalline solid with a faint amine-like odor. It is a commercially important chemical used in the production of dyes and hair coloring products.
The molar mass of m-Phenylenediamine is approximately 108.14 g/mol, with a density of about 1.25 g/cm³. This places it in a range similar to common household items such as sugar (molar mass around 342.3 g/mol) and table salt (density around 2.16 g/cm³).
m-Phenylenediamine has a melting point of around 64-66°C and a boiling point of around 282-284°C. These values are comparable to common household items like butter (melting point around 32°C) and water (boiling point at 100°C).
m-Phenylenediamine is sparingly soluble in water, forming a clear solution. It has a relatively high viscosity compared to water, but lower compared to honey. This makes it more soluble in water and less viscous than common household items like oils and honey.
🏭 Production & Procurement
m-Phenylenediamine, a chemical compound commonly used in the production of hair dyes and rubber antioxidants, is typically produced through the reaction of aniline with nitrobenzene. This process involves the reduction of nitrobenzene to m-phenylenediamine using hydrogen gas and a catalyst such as palladium, nickel, or iron. The resulting m-phenylenediamine is then purified to remove any impurities before being used in various industrial applications.
m-Phenylenediamine can be procured from chemical manufacturers or suppliers who produce and sell the compound. Once procured, m-phenylenediamine is commonly transported in liquid form in drums or tanks to industrial facilities where it will be used in the production of hair dyes, rubber antioxidants, and other products. The transportation of m-phenylenediamine must adhere to strict safety regulations to prevent leaks or spills that could pose a risk to human health or the environment.
⚠️ Safety Considerations
Safety considerations for m-Phenylenediamine include potential skin and eye irritation, respiratory irritation, and the risk of sensitization. It is important to use appropriate personal protective equipment, such as gloves, goggles, and masks, when handling this chemical. Adequate ventilation should be ensured to minimize exposure to fumes or vapors. In case of accidental exposure, immediate medical attention is recommended.
m-Phenylenediamine is a chemical compound commonly used in the production of various products, such as hair dyes and rubber chemicals. It is known to have moderate acute toxicity if ingested or inhaled. The compound has the potential to cause skin and eye irritation upon contact, as well as respiratory irritation if inhaled. It is important to handle this chemical with caution to prevent adverse health effects.
Hazard statements for m-Phenylenediamine include “Causes skin irritation,” “Causes serious eye damage,” and “May cause respiratory irritation.” These statements highlight the potential hazards associated with exposure to this chemical. It is crucial to follow proper handling procedures and safety precautions to minimize the risk of harm. In case of exposure, immediate medical attention should be sought to address any health concerns.
