Understanding CAS Number 111-42-2 The Properties and Applications of Diethanolamine

CAS number 111-42-2 refers to a chemical compound known as diethanolamine (DEA), a versatile organic compound that plays a crucial role in various industrial and chemical applications. This article delves into the properties, uses, safety considerations, and regulatory status of diethanolamine.

Chemical Structure and Properties

Diethanolamine is an alkanolamine, comprising two ethanolamine groups. Its molecular formula is C4H11NO2, and it has a molar mass of 103.14 g/mol. This compound appears as a colorless to pale yellow viscous liquid with a faint amine odor. Its solubility in water is significant, making it an effective agent in numerous aqueous formulations.

The compound has a relatively high boiling point of approximately 202°C and a density of about 1.1 g/cm³. Diethanolamine exhibits both basic and alcohol properties, which allows it to participate in various chemical reactions and act as a surfactant, emulsifier, and stabilizer.

Diethanolamine is widely used in various industries, primarily due to its multifunctional characteristics. Some prominent applications include

1. Personal Care Products DEA is commonly utilized in the formulation of cosmetics and personal care products, serving as a pH balancer and emulsifier. It helps stabilize creams and lotions, ensuring a smooth texture and enhancing the delivery of active ingredients.

2. Industrial Cleaners The compound is employed in producing industrial cleaning agents. Its surfactant properties enable it to effectively break down oils, greases, and other contaminants, making it an invaluable ingredient in many industrial cleaning formulations.

3. Chemical Manufacturing Diethanolamine finds usage in the production of various chemicals, including surfactants, corrosion inhibitors, and agricultural products. It acts as a precursor for the synthesis of other chemical compounds, expanding its role in industrial chemistry.

4. Gas Treatment One notable application of DEA is in the field of gas treatment, where it is utilized for removing carbon dioxide and hydrogen sulfide from natural gas and other gaseous streams. Its ability to react with these acidic gases helps purify hydrocarbons, making it integral to the oil and gas industry.

Safety Considerations

While diethanolamine has numerous benefits, it is essential to be aware of its safety considerations. The compound may cause skin and eye irritation upon direct contact, and inhalation of its vapors can lead to respiratory issues. Therefore, appropriate safety equipment, such as gloves and goggles, should be worn when handling DEA.

Moreover, there are ongoing discussions regarding the potential carcinogenicity of diethanolamine. Although it is not classified as a carcinogen by major regulatory agencies, prolonged exposure and high concentrations might pose health risks. Consequently, manufacturers and users must adhere to safety guidelines and regulations to mitigate any potential hazards.

Regulatory Status

Diethanolamine is regulated by various agencies worldwide. In the United States, the Environmental Protection Agency (EPA) monitors its use under the Toxic Substances Control Act (TSCA). Similarly, in the European Union, diethanolamine is subject to regulations under the Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH) legislation.

Manufacturers and users of diethanolamine are urged to comply with these regulations to ensure safe usage and to minimize any potential environmental impact.

Conclusion

Diethanolamine, represented by CAS number 111-42-2, is a remarkable chemical compound with diverse applications across various industries. From personal care products to industrial cleaning agents and gas treatment, its multifunctional properties make it indispensable. However, the importance of safety and adherence to regulatory standards cannot be overstated. As industries continue to innovate, the role of diethanolamine will likely evolve, warranting ongoing research and scrutiny to maximize its benefits while ensuring safety and environmental stewardship.
