Ethylene glycol gc spectrum
WebDEG is synthesized from the reaction of ethylene oxide with ethylene glycol, therefore, DEG can contain ethylene glycol (EG), a toxic impurity [4]. The US-FDA is concerned about potential risks from chronic exposure to DEG. There is also a concern, in certain populations, of DEG exposure to children and individuals with kidney or liver disease. WebAug 1, 1974 · The authors developed a method for detection and quantitation of ethylene glycol in serum, based on the gas chromatography of its dibenzoate ester. No special reagents or equipment are required ...
