Sodium telluride
基本信息
| 应用 | Sodium telluride is used as a semiconductor, as a reducing agent and to prepare organic tellurium compounds. It is used in the reduction of aromatic carbonyl compounds to alcohols. It is also used in the preparation of pyrrolo[2,3-d]pyrimidines (7-deaza-9H-purines) from aromatic nitriles. It is used to prepare nanocrystalline zinc telluride. |
| 备注 | Air and moisture sensitive. Hygroscopic in nature. It oxidizes in air to from polytellurides. Keep the container tightly closed. Incompatible with acid, oxidizing agents and water. |
