Anwendungen

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.

Bemerkungen

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.
