2-Butoxyethanol

2-Butoxyethanol is an organic compound with the chemical formula C₆H₁₄O₂. It is a colorless liquid with a sweet, ether-like odor. It is a member of the glycol ether family and is commonly used as a solvent in various industrial and household applications.

Chemical Structure and Properties

2-Butoxyethanol is an ether and an alcohol, characterized by the presence of a butoxy group (C₄H₉O) attached to an ethylene glycol moiety. Its molecular structure can be represented as CH₃(CH₂)₃OCH₂CH₂OH. It has a molecular weight of 118.17 g/mol.

Physical Properties

• Boiling Point: 171 °C (340 °F)
• Melting Point: -70 °C (-94 °F)
• Density: 0.90 g/cm³
• Solubility: Miscible with water and most organic solvents

Uses

2-Butoxyethanol is widely used as a solvent due to its ability to dissolve both polar and non-polar substances. It is commonly found in:

• Cleaning Products: Used in household cleaners, degreasers, and industrial cleaning agents.
• Paints and Coatings: Acts as a solvent in paints, varnishes, and inks.
• Textile Industry: Used in the dyeing and finishing of textiles.
• Hydraulic Fluids: Component in hydraulic brake fluids.

Health and Safety

Exposure to 2-butoxyethanol can occur through inhalation, ingestion, or skin contact. It is important to handle this chemical with care due to its potential health effects:

• Acute Exposure: Can cause irritation of the eyes, skin, and respiratory tract. High levels of exposure may lead to headaches, dizziness, and nausea.
• Chronic Exposure: Prolonged exposure may affect the liver and kidneys.

The Occupational Safety and Health Administration (OSHA) and other regulatory bodies have set exposure limits to protect workers from the potential hazards of 2-butoxyethanol.

Environmental Impact

2-Butoxyethanol is biodegradable and does not persist in the environment. However, it can contribute to air and water pollution if not properly managed. It is important to follow proper disposal methods to minimize environmental impact.

Regulation

Due to its potential health effects, the use of 2-butoxyethanol is regulated in many countries. Safety data sheets (SDS) and proper labeling are required to inform users of the risks and safe handling practices.
