Useful:

• Canonical SMILES: [Na][Te][Na]
• Uses: 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.

Technology Process of Sodium telluride

There total 42 articles about Sodium telluride which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 100.0%

tellurium (14683-12-6) + sodium (7440-23-5) → disodium telluride (12034-41-2)

Guidance literature:

In neat (no solvent); Na was warmed in high vacuum and added to liquid Te in N2 atmosphere, NH3 was condensed over the mixture, the NH3 was slowly evaporated;; tempered at 400-500°C, stored under N2;;

Reference yield: 100.0%

tellurium (14683-12-6) + sodium dithionite → disodium telluride (12034-41-2)

Guidance literature:

In sodium hydroxide; Te was treated with Na2S2O4 in NaOH(10%) soln. at 75-80°C under H2 (free from O2);;

Reference yield: 98.0%

tellurium (14683-12-6) + sodium triethylborohydride → disodium telluride (12034-41-2)

Guidance literature:

In 1,2,5-trimethyl-benzene; byproducts: H2, B(CH2CH3)3; Ar atmosphere, 150°C (11.5 h); elem. anal.;

upstream raw materials:

tellurium

rongalite

sodium

tellurite^(2-)

Downstream raw materials:

mercury(II) telluride

tungsten ditelluride

manganese ditelluride

bis(trimethylsilyl) telluride
