Understanding CAS Number 139-07-1 The Significance and Applications of Phenol

Introduction

The Chemical Abstracts Service (CAS) number 139-07-1 refers to Phenol, an aromatic organic compound that plays a crucial role in various industrial applications. Phenol, also known as carbolic acid, has a distinct structure characterized by a hydroxyl group (-OH) attached to a benzene ring. It is a colorless to light pink solid at room temperature and possesses a distinctive sweet, tar-like odor. In this article, we will explore the properties, uses, and safety considerations associated with Phenol.

Chemical Structure and Properties

Phenol has the molecular formula C6H5OH. Its structure consists of a benzene ring bonded to a single hydroxyl group, making it a simple aromatic alcohol. This structure gives Phenol both hydrophobic and hydrophilic properties, enabling it to dissolve in water in limited amounts and to engage in hydrogen bonding. Phenol has a melting point of approximately 40.5 °C and a boiling point of around 181.7 °C. Its relatively high melting and boiling points can be attributed to the presence of hydrogen bonds between Phenol molecules.

Industrial Uses

Phenol is primarily produced through the catalytic reforming of naphtha or from cumene, a petrochemical intermediate. Its versatility leads to a wide range of industrial applications

3. Antiseptics and Disinfectants Due to its antibacterial properties, Phenol has historically been used as a disinfectant in medical settings. However, its use in this capacity has diminished in favor of safer alternatives.

4. Laboratory Reagent In laboratories, Phenol is commonly used as a reagent for various chemical reactions and analyses.

5. Developing Dyes and Pigments Phenol derivatives are integral in the production of dyes and pigments, enabling vibrant colors in textiles and plastics.

Environmental and Safety Considerations

While Phenol has many beneficial applications, it is also important to acknowledge the potential risks associated with its use. Phenol is toxic and can cause harm if ingested, inhaled, or absorbed through the skin. Short-term exposure may result in symptoms such as irritation of the skin, eyes, and respiratory tract. Long-term exposure can lead to more severe health effects, including damage to the liver, kidneys, and nervous system.

Due to its environmental impact, regulations exist regarding its disposal and usage. In wastewater, Phenol must be treated appropriately to prevent ecological damage, as it can be detrimental to aquatic life.

Conclusion

CAS number 139-07-1, representing Phenol, is an essential compound with diverse applications across multiple sectors, including medicine, manufacturing, and laboratories. Its unique chemical structure allows it to serve as a precursor for numerous important products, particularly in the production of plastics, pharmaceuticals, and dyes. However, it is imperative for industries and researchers to handle Phenol with care, taking into account its toxicity and potential environmental risks. As society continues to innovate and rely on chemical compounds, understanding substances like Phenol is vital for ensuring safety and sustainability in industrial practices.
