Dimethyl decyl amine, with a CAS No. of 61788-93-0, is an organic compound belonging to the category of amines. Here is a detailed introduction to this chemical, organized based on its characteristics:

Chemical Identity

Dimethyl decyl amine, also known as N,N-dimethyl decylamine, has a molecular formula of C12H27N. It is a specific amine compound distinguished by its decyl (C10H21) alkyl chain attached to the nitrogen atom, along with two methyl (CH3) groups.

Physical Properties

This chemical typically appears as a clear, colorless to pale yellow liquid. Its physical properties include a density of approximately 0.778 g/mL at 25°C, a boiling point of around 234°C, and a flash point of 197°F (91.7°C). The refractive index is n20/D 1.431. These properties make it suitable for use in various applications where its liquid form and chemical stability are advantageous.

Chemical Properties

Dimethyl decyl amine is a tertiary amine, which means it has three alkyl groups attached to the nitrogen atom. This structural feature influences its chemical reactivity. It is generally stable under normal conditions but can react with acids to form ammonium salts. The amine group is also susceptible to nucleophilic substitution reactions, allowing for further chemical modifications.

Applications

Due to its unique properties, dimethyl decyl amine finds applications in several fields:

1. Surfactant Production: It is used in the production of surfactants, such as emulsifiers, detergents, and wetting agents. Its amphiphilic nature makes it effective in reducing surface tension and stabilizing emulsions.
2. Intermediate in Chemical Synthesis: As an intermediate, it is used in the synthesis of various chemicals, including quaternary ammonium compounds, betaines, and amines. These derivatives have their own unique applications in different industries.
3. Metal Corrosion Inhibitor: It can be used as a corrosion inhibitor for metals, protecting them from environmental degradation.
4. Bactericide and Fungicide: Its bactericidal and fungicidal properties make it suitable for use in agricultural and industrial settings to control microbial growth.

Safety and Handling

Dimethyl decyl amine should be handled with caution due to its potential hazards. It is classified as a flammable liquid and can be harmful if swallowed or in contact with skin or eyes. Proper personal protective equipment (PPE), such as eye shields, face shields, gloves, and respirators, should be worn during handling. It should be stored in a sealed container in a cool, dry place, away from heat, sparks, and open flames. In case of spillage or leakage, appropriate cleanup measures should be taken to prevent environmental contamination.

In summary, dimethyl decyl amine is a versatile amine compound with a range of applications in different industries. Its chemical properties and physical state make it suitable for use in surfactant production, chemical synthesis, metal corrosion inhibition, and bactericidal applications. However, due to its potential hazards, proper handling and storage practices are essential to ensure safety.
