Combustible. | | Uses | Triethylene glycol dimethyl ether is used as a solvent for gases and coupling immiscible liquid. It is also used to prepare perfluoro-triethyleneglycoldimethylether. | | Uses | Triethylene glycol dimethyl ether may be used as an analytical standard for the quantification of the analyte in water samples using in vitro bioassays and chemical screening technique. | | Uses | Labelled Triglyme. It is used as a solvent. | | Definition | ChEBI: A polyether that consists of dodecane in which the carbon atoms at positions 2, 5, 8 and 11 are replaced by oxygen atoms. | | Reactivity Profile | TRIETHYLENE GLYCOL DIMETHYL ETHER forms explosive peroxides on prolonged exposure to air. Its decomposition products may be sensitive to shock. The bulk chemical is stable for 2 weeks at temperatures up to 140° F when protected from light. TRIETHYLENE GLYCOL DIMETHYL ETHER is incompatible with strong oxidizers. TRIETHYLENE GLYCOL DIMETHYL ETHER is also incompatible with strong acids. TRIETHYLENE GLYCOL DIMETHYL ETHER may react with peroxides, oxygen, nitric acid and sulfuric acid. . | | Flammability and Explosibility | Nonflammable | | Purification Methods | Reflux it with, and distil it from sodium hydride or LiAlH4.
