General description
Diethylene glycol dimethyl ether (diglyme), a less volatile liquid, is widely employed as an anhydrous solvent. Various physical properties (density, refractive index, speed of sound and shear viscosity) of its mixtures with ethyl acetate, methyl benzoate, ethyl benzoate or diethyl succinate have been evaluated at various temperature ranges.
Application
Diethylene glycol dimethyl ether (diglyme) was used for the immobilization of biological compounds onto a gold surface via dextran chemistry. It was employed as solvent for the functionalization of carbon nano fibers, via the Diels Alder reaction. It may be used in the preparation of linear poly(glycidol) (PG), via anionic polymerization. It may be used as solvent for the extraction of tattoo colorants and their degradation products from various media by recovery experiments and HPLC-diode array detector technology.

Tattooing is a widespread process of puncturing pigments into skin, whereas the resulting concentration inside the skin remains unknown. Many tattoo colorants are organic pigments, such as azo pigments, manufactured for other uses. To remove tattoos from skin, laser pulses
