627-54-3 - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| physical properties | diethyl tellurium is a pale yellow liquid with strong garlic odor at normal temperature and pressure, highly toxic. Unstable in air, ignition at room temperature. Practically insoluble in water, soluble in ethanol. |
| Application | diethyltellurium is an organometallic compound, which can be used to prepare infrared detection materials; Tellurium source for preparing CdHgTe; group II-VI tellurium-containing semiconductor compounds were prepared. |
| synthesis method | HCHO,NaHSO3.2H2O are used to directly react with Te, etc. under alkaline conditions, and the reaction is carried out in an inert atmosphere. The reaction material was subjected to a synthesis reaction in a synthesis apparatus under the protection of nitrogen, and heated and stirred until the reaction was terminated. High purity liquid products can be obtained by steam distillation, drying and vacuum distillation under the protection of nitrogen. |
| storage method | diethyl tellurium can be stored in a sealed, light-protected, ventilated and dry place at room temperature. Diethyltellurium non-corrosive, packaging materials can be used at room temperature: carbon steel, stainless steel, nickel, copper, brass, Polychlorotrifluoroethylene and polyethylene tetraethylene. The organometallic compound is anaerobic anaerobic to water, self-igniting in air. The reaction must therefore be carried out in an inert gas atmosphere. The reaction device was placed in an exhaust cabinet. Staff should wear fire-resistant gloves, boots, aprons, lead-coated asbestos protectors or aluminized glass fiber protectors. |
| production method | using HCHO,NaHSO3.2H2O is directly reacted with Te or the like under alkaline conditions, and the reaction is carried out in an inert atmosphere. The reaction material was subjected to a synthesis reaction in a synthesis apparatus under the protection of nitrogen, and heated and stirred until the reaction was terminated. High purity liquid products can be obtained by steam distillation, drying and vacuum distillation under the protection of nitrogen. |
