M-Phenylenediamine, also known as 1,3-diaminobenzene, is a crucial organic compound with a wide range of applications in various industries. As a reliable supplier of M-Phenylenediamine, I am delighted to share detailed information about its chemical formula and other related aspects.
Chemical Formula of M-Phenylenediamine
The chemical formula of M-Phenylenediamine is C₆H₄(NH₂)₂. This formula reveals that it consists of a benzene ring (C₆H₄) with two amino groups (-NH₂) attached at the meta-positions. The meta-positions mean that the two amino groups are separated by one carbon atom on the benzene ring. This structural arrangement gives M-Phenylenediamine its unique chemical and physical properties.
Structural Features
The presence of the benzene ring provides M-Phenylenediamine with aromaticity, which is characterized by stability and resonance. The two amino groups are electron-donating groups, which can influence the reactivity of the benzene ring. They can participate in various chemical reactions, such as substitution reactions, oxidation reactions, and condensation reactions.
Physical and Chemical Properties
- Physical State: M-Phenylenediamine is a white to light brown crystalline solid at room temperature.
- Melting Point: It has a melting point of around 62 - 64 °C.
- Solubility: It is slightly soluble in water but more soluble in organic solvents such as ethanol, ether, and chloroform.
- Chemical Reactivity: Due to the presence of amino groups, M-Phenylenediamine is a weak base. It can react with acids to form salts. For example, it can react with hydrochloric acid to form M-Phenylenediamine dihydrochloride.
Applications
- Dye Industry: M-Phenylenediamine is a key intermediate in the production of various dyes, including azo dyes and sulfur dyes. These dyes are widely used in the textile, leather, and paper industries for coloring purposes.
- Rubber Industry: It is used as an antioxidant and accelerator in the rubber industry. It can improve the aging resistance and mechanical properties of rubber products.
- Pharmaceutical Industry: M-Phenylenediamine can be used as a raw material for the synthesis of some pharmaceutical intermediates. For example, it can be used in the synthesis of P-Phenylenediamine, which is an important intermediate in the production of some drugs.
- Other Applications: It is also used in the production of photographic developers, pesticides, and other fine chemicals.
Comparison with Related Compounds
- P-Phenylenediamine: P-Phenylenediamine has the same molecular formula as M-Phenylenediamine (C₆H₄(NH₂)₂), but the two amino groups are attached at the para-positions on the benzene ring. P-Phenylenediamine is more reactive than M-Phenylenediamine due to the different electronic effects of the amino groups. It is widely used in hair dyes and other applications. You can find more information about P-Phenylenediamine here.
- O-Phenylenediamine: O-Phenylenediamine has the amino groups attached at the ortho-positions on the benzene ring. It has different chemical and physical properties compared to M-Phenylenediamine. For example, it is more easily oxidized than M-Phenylenediamine.
