2-Methoxyethanol, also known as ethylene glycol monomethyl ether or methyl cellosolve, is a common solvent.

Properties

Chemical

Methyl cellosolve is both a primary alcohol and an ether.

Physical

Methyl cellosolve is a colorless liquid, with an ethereal odor. It is miscible with water and most organic solvents.

Availability

Many OTC paint and dye solvents have this compound in their composition. Fractional distillation is required to isolate the compound.

Preparation

Industrially, methyl cellosolve is produced by the reaction of methanol with ethylene oxide.

Projects

  • Paint stripper

Handling

Safety

Methyl cellosolve is an endocrine disruptor. It is toxic to the bone marrow and testes.

Storage

2-Methoxyethanol should be kept in closed bottles. BHT is sometimes added as stabilizer.[1]

Disposal

Incineration outside should suffice.
