General description

Diethylene glycol methyl ether is an organic compound that is commonly used as an industrial solvent. It is used as a potential solvent for the separation of aromatic-paraffinic compounds.

Application


  • Composition-explicit distillation curves of diesel fuel with glycol ether and glycol ester oxygenates: fuel analysis metrology to enable decreased particulate emissions.: Investigates the incorporation of diethylene glycol methyl ether into diesel fuels to reduce particulate emissions. This research is vital for environmental science, focusing on improving air quality and reducing the ecological impact of diesel engines (Smith BL et al., 2008).
