Dimethylbenzylamine

Dimethylbenzylamine (DMBA) is a chemical compound used primarily as a catalyst in the production of polyurethane foams and elastomers. It is a colorless liquid with a faint, amine-like odor.

Chemical Properties[edit | edit source]

DMBA is a tertiary amine, meaning it has three organic substituents attached to the nitrogen atom. Its chemical formula is C9H13N. It is soluble in water and most organic solvents, and it has a boiling point of 194°C.

Uses[edit | edit source]

The primary use of DMBA is as a catalyst in the production of polyurethane foams and elastomers. It is also used in the production of epoxy resins, where it acts as a hardener. In addition, it is used as a corrosion inhibitor in the oil and gas industry.

Health Effects[edit | edit source]

Exposure to DMBA can cause irritation to the eyes, skin, and respiratory tract. It can also cause nausea, headache, and dizziness. Long-term exposure can lead to liver and kidney damage. Therefore, it is important to handle this chemical with care and use appropriate personal protective equipment.

Safety[edit | edit source]

DMBA is classified as a flammable liquid and a health hazard. It should be stored in a cool, well-ventilated area away from heat sources and open flames. In case of a spill, it should be cleaned up immediately using absorbent materials.

Regulation[edit | edit source]

In the United States, DMBA is regulated by the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA). These agencies set limits on the amount of DMBA that can be released into the environment and the level of exposure that is considered safe for workers.
