Properties and stability
Use and store according to specifications, no decomposition will occur, and avoid contact with oxides
Storage method
Stored in a cool, dry, well-ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The packaging is sealed. They should be stored separately from acids and food chemicals, and avoid mixed storage. Suitable materials should be available in the storage area to contain spills.
Synthesis method
It can be prepared by reacting tert-butane chloride with silver nitrate in ether, or by passing nitrogen dioxide or a mixture of nitrogen monoxide and nitrogen dioxide into tert-butyl chloride at 25-30°C. It can be prepared by reacting with butanol, or by reacting tert-butyl alcohol with sodium nitrite and sulfuric acid.
Purpose
Intermediates of vasopressin, rocket fuel, and organic synthesis reagents.
