Manufacture

Dimethylaminoethoxyethanol is manufactured by reacting dimethylamine and ethylene oxide.^[2] Other methods are also available producing streams rich in the substance which then need to be further purified.^[3]

Uses

As dimethylaminoethoxyethanol is weakly basic,^[4] it has been studied as a method of absorbing Greenhouse gases and in particular carbon dioxide.^[5][6][7][8]

Dimethylaminoethoxyethanol is used extensively in surfactants which have also been evaluated as corrosion inhibitors.^[9] Surfactants prepared are usually cationic and may also be used as a biocide.^[10] This is particularly important for oilfield applications against Sulfate-reducing microorganisms.

The material has other uses which include:

• General such as clays, intermediates, plasticizers and adhesives.^[11]
• As a catalyst and especially for polyurethanes.^[12][13]
• Process regulators
• Propellants and blowing agents

Toxicity

The toxicity of dimethylaminoethoxyethanol has been extensively studied.^[14]
