Dimethyl tetradecyl amine, with a CAS No. of 68439-70-3, is a specific type of amine that possesses distinct chemical characteristics. Here is a detailed introduction to this chemical, structured according to its properties:

Chemical Identity

Dimethyl tetradecyl amine is a long-chain aliphatic amine, also known as N,N-dimethyl-1-tetradecanamine or C14H29(CH3)2N. Its molecular structure features a tetradecyl (C14) alkyl chain attached to two methyl groups through a nitrogen atom, making it a tertiary amine.

Physical Properties

This chemical appears as a clear, colorless to pale yellow liquid with a mild amine odor. It is non-aqueous, meaning it is insoluble in water, but readily soluble in organic solvents such as ethanol, ether, and aromatic hydrocarbons. Its viscosity and density may vary slightly depending on the purity and manufacturing process.

Chemical Properties

Dimethyl tetradecyl amine exhibits typical tertiary amine characteristics, including basicity and reactivity. It can react with acids to form quaternary ammonium salts, and its nitrogen atom can participate in nucleophilic substitution reactions. Due to its aliphatic nature, it is relatively stable under normal conditions but can undergo oxidation or degradation at high temperatures or in the presence of oxidizing agents.

Applications

Dimethyl tetradecyl amine finds applications in various industries due to its unique properties:

1. Surfactants and Emulsifiers: Its amphiphilic nature makes it an excellent surfactant and emulsifier, used in personal care products, detergents, and industrial cleaning formulations.
2. Lubricants and Additives: It enhances the lubricating properties of oils and greases, reducing friction and wear. In addition, it serves as an additive in fuels and plastics to improve their performance.
3. Textile Treatment: As a textile auxiliary, it improves the softness, smoothness, and antistatic properties of fabrics.
4. Agricultural Chemicals: It acts as a carrier or adjuvant in the formulation of pesticides and fertilizers, enhancing their effectiveness and spreadability.

Safety and Handling

Dimethyl tetradecyl amine should be handled with caution due to its potential health hazards. It is recommended to wear protective clothing, gloves, and eye protection when handling this chemical. It should be stored in a cool, dry, and well-ventilated place, away from heat, sparks, and open flames. In case of contact with skin or eyes, immediate rinsing with plenty of water is recommended, followed by medical attention if necessary. Additionally, following the safety data sheet (SDS) for this chemical is crucial for safe handling and disposal.
