Allgemeine Beschreibung

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.

Anwendung

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.

Two different surface chemistries have been studied for the development of surface plasmon resonance imaging (SPRI) based DNA microarray affinity sensors: (1) 11-mercaptoundecanoic acid-poly(ethylenimine) (MUA-PEI) and (2) dextran procedures. The MUA-PEI method consists of assembling a multilayer on the basis

Polyethylene glycol (PEG)-like films were grafted onto various substrates by plasma polymerization of diethylene glycol dimethyl ether (diglyme). Low-power diglyme plasma conditions yielded PEG-like films exhibiting nonfouling behavior, as evidenced by the significant decrease in protein adsorption and cell attachment
