glycolmethanol

Glycolmethanol is an organic compound in the class of glycol ethers. It is commonly referred to as ethylene glycol monomethyl ether (EGME) or 2-methoxyethanol, and has the chemical formula C3H8O2. In industry it is used primarily as a solvent and as an intermediate in chemical production.

Glycolmethanol is produced by the etherification of methanol with ethylene oxide, forming the ether alcohol HO-CH2-CH2-O-CH3. It is a colorless, relatively polar liquid that is miscible with water and many organic solvents. As a solvent, it dissolves resins, dyes, and surface-coating agents, and it is employed in paints, coatings, inks, cleaning formulations, and other industrial formulations.

Safety and regulation: glycolmethanol is toxic and has potential reproductive and developmental hazards in humans. It is restricted or subject to occupational exposure limits in many jurisdictions, and handling typically requires appropriate engineering controls, ventilation, and personal protective equipment. The substance is flammable, and vapors can form ignitable mixtures with air. It is also toxic to aquatic life and should be prevented from entering waterways.

Environmental and disposal notes: glycolmethanol is not typically persistent in the environment, but accidental releases must be managed according to local regulations. Waste streams containing the compound are handled as hazardous waste under applicable rules, with appropriate containment and treatment.
