Production Process of Sodium Azide
Sodium Azide is prepared from Sodium Amide at desired pressure and high temperatures in reaction with Nitrous Oxide. In the process Sodium Amide is converted to Sodium Azide and Sodium Hydroxide. The hot reaction mixture is cooled and transferred from the reactor for isolation and purification of Sodium Azide. The purification process involves leaching and washing of Sodium Azide and Sodium Hydroxide mixture to separate Sodium hydroxide from Sodium Azide. Wet Sodium Azide
is obtained from the purification stage and is dried to get crystalline powder. Sodium hydroxide separated from Sodium Azide is disposed off as a caustic lye.

Extract of DRHP of Alkali Metals Limited 
Increased sales of sodium derivatives, from 1205 MTs during FY 2005 to 1669 MTs during FY
2006 also boosted the growth in sales.
The increase in the turnover during the FY 2005-06 is mainly attributed to the increase in
sales of the product Sodium Azide which increased from Rs. 81 Mn to Rs. 226 Mn in the FY
2006. The increase in sales was due to the bird flu virus that had spread throughout the world
and Sodium Azide is an ingredient used in the drug manufactured to cure the infection caused
from the virus.
