Glycol ethers

Glycol ethers are a group of solvents based on alkyl ethers of ethylene glycol, also sometimes called Cellosolve. These solvents typically have higher boiling point, together with the favorable solvent properties of lower molecular weight ethers and alcohols. The original glycol ether is ethyl cellosolve.

Glycol ethers can be also derived of diethylene glycol (carbitols). Acetates of glycols are a similar kind of potent solvents.

Glycol ether solvents include:

Ethylene glycol monomethyl ether (2-methoxyethanol, CH₃OCH₂CH₂OH)

Ethylene glycol monoethyl ether (2-ethoxyethanol, CH₃CH₂OCH₂CH₂OH)

Ethylene glycol monopropyl ether (2-propoxyethanol, CH₃CH₂CH₂OCH₂CH₂OH)

Ethylene glycol monoisopropyl ether (2-isopropoxyethanol, (CH₃)₂CHOCH₂CH₂OH)

Ethylene glycol monobutyl ether (2-butoxyethanol, CH₃CH₂CH₂CH₂OCH₂CH₂OH), a widely used solvent in paintings and surface coatings, cleaning products and inks

Ethylene glycol monophenyl ether (2-phenoxyethanol, C₆H₅OCH₂CH₂OH)

Ethylene glycol monobenzyl ether (2-benzyloxyethanol, C₆H₅CH₂OCH₂CH₂OH)

Diethylene glycol monomethyl ether (2-(2-methoxyethoxy)ethanol, methyl carbitol, CH₃OCH₂CH₂OCH₂CH₂OH)

Diethylene glycol monoethyl ether (2-(2-ethoxyethoxy)ethanol, carbitol cellosolve, CH₃CH₂OCH₂CH₂OCH₂CH₂OH)

Diethylene glycol mono-n-butyl ether (2-(2-butoxyethoxy)ethanol, CH₃CH₂CH₂CH₂OCH₂CH₂OCH₂CH₂OH)

Dialkyl ethers:

Ethylene glycol dimethyl ether (dimethoxyethane, CH₃OCH₂CH₂OCH₃), a higher boiling alternative to diethyl ether and THF, also used as a solvent for polysaccharides, a reagent in organometallic chemistry and in some electrolytes of lithium batteries
