Chemical structure of 2-Butoxyethanol

2-Butoxyethanol consists of a butyl group attached to an ethylene glycol moiety. Its molecular structure can be represented as C₄H₉OCH₂CH₂OH. The presence of both hydrophobic and hydrophilic groups in its structure makes it an effective solvent for both polar and non-polar substances.

Physical properties

2-Butoxyethanol is a clear, colorless liquid at room temperature. It has a boiling point of approximately 171 °C and a melting point of -70 °C. It is miscible with water and most organic solvents, which makes it versatile in various applications.

Chemical properties

As a glycol ether, 2-butoxyethanol is stable under normal conditions but can undergo oxidation to form butoxyacetic acid. It is also capable of forming peroxides upon prolonged exposure to air.

Uses

2-Butoxyethanol is widely used in industrial and household products due to its solvent properties. It is commonly found in:

• Paints and coatings: Used as a solvent to improve the flow and application of paints.
• Cleaning products: Utilized in glass cleaners, surface cleaners, and degreasers for its ability to dissolve oils and greases.
• Printing inks: Acts as a solvent to enhance the drying and adhesion of inks.
• Textile processing: Used in the dyeing and finishing of textiles.

Health and safety

Exposure to 2-butoxyethanol can occur through inhalation, ingestion, or skin contact. It is known to cause irritation to the eyes, skin, and respiratory tract. Prolonged exposure may lead to more serious health effects, including hemolysis and liver and kidney damage.

Regulation

Due to its potential health effects, the use of 2-butoxyethanol is regulated in many countries. Occupational exposure limits have been established to protect workers from its harmful effects.

Environmental impact

2-Butoxyethanol is biodegradable and does not persist in the environment. However, its widespread use and potential for release into the environment necessitate careful handling and disposal to minimize ecological impact.
