Exploring the Properties and Applications of Chemicals with CAS Number 139-07-201 in Industry

Understanding CAS No. 139-07-1 An Overview of Benzyl Alcohol

CAS No. 139-07-1 refers to benzyl alcohol, a simple aromatic alcohol widely used in various industries due to its versatile properties. Benzyl alcohol is chemically represented as C7H8O and is characterized by its hydroxyl group (-OH) attached to a benzyl group (C6H5CH2-). It is a colorless liquid with a pleasant aromatic scent, reminiscent of flowers, which makes it a popular choice in fragrances and cosmetics.

Physical and Chemical Properties

Benzyl alcohol has a boiling point of 205 °C and a melting point of -15 °C, making it a liquid at room temperature. Its density is around 1.04 g/cm³, and it is soluble in alcohols, ethers, and some other organic solvents but has limited solubility in water. This solubility profile is significant for its application in various chemical processes.

Chemically, benzyl alcohol can act as a primary alcohol, allowing it to participate in reactions typical of alcohols, such as oxidation to form benzaldehyde. It can also undergo esterification to produce benzyl esters, which are prevalent in the fragrance and flavoring industries. Moreover, benzyl alcohol has a relatively low toxicity profile, which further enhances its utility across different sectors.

Applications of Benzyl Alcohol

Benzyl alcohol is predominantly used as a solvent in the formulation of various products. In the pharmaceutical industry, it serves as an excipient in drug formulations, helping to dissolve active ingredients and enhance their effectiveness. Its properties as a preservative and antibacterial agent make it valuable in the formulation of injectable medications.

In cosmetics and personal care products, benzyl alcohol is utilized for its aromatic qualities and as a preservative to extend shelf life. It is found in numerous products, such as lotions, shampoos, and perfumes, contributing both scent and functionality. Furthermore, it is effective in preventing microbial growth, hence being a common choice in formulations where preservation is critical.

Benzyl alcohol also plays a vital role in the manufacturing of plastics, resins, and other chemical compounds. It is employed in producing benzyl benzoate, which finds applications in the production of certain types of plastics and synthetic fibers. Additionally, its solvent properties make it popular in the paint and coatings industry, where it is used to dissolve various substances and improve product performance.

Safety and Environmental Considerations

While benzyl alcohol is generally regarded as safe when used appropriately, it is essential to consider handling precautions. Prolonged exposure to its vapors might cause irritation to the skin, eyes, and respiratory tract. Therefore, it is crucial to use personal protective equipment (PPE) when working with this compound, particularly in industrial settings.

Moreover, the environmental impact of benzyl alcohol is relatively low compared to other solvents. It is biodegradable and is not classified as a hazardous air pollutant. Nevertheless, it is advisable to manage its disposal carefully to minimize any potential ecological risks.

Conclusion

In summary, benzyl alcohol (CAS No. 139-07-1) is a multifaceted compound with wide-ranging applications and a favorable safety profile. Its use as a solvent, preservative, and fragrance enhancer marks it as an indispensable ingredient across the pharmaceutical, cosmetic, and chemical industries. Understanding its properties and applications aids in leveraging its benefits while ensuring safe and responsible usage. As industries continue to evolve, benzyl alcohol will likely maintain its relevance due to its versatile and beneficial characteristics.
