Dear Sisir,

 

Why don't you address your email straight to Dr Chaganbhai informing
Hydrazine hydrate is easily available in all towns of India. So he wouldn't
require to ask the recipe to everybody on this list.

Dear Professor Zabicky,

Hydrazine hydrate is very easily available in all towns of India. I have
failed to understand why the mailers are insisting about a process. The
mails reflect otherwise.

Warm Regards,

Sisir Adhikari

Hello, You may try the synthesis of hydrazine sulfate or other salts as
appear =20= in
http://www.worldwideschool.org/library/books/sci/chemistry/=20
OrganicSynthesis/chap10.html followed by neutralization with a base, or
precipitation with an =20 alkaline earth hydroxide slack and further
purification. In any case, =20= you should work in a well protected
environment, because the reagents =20= and products are very toxic. If it is
only to save some money, IMO by =20= the end of the process it will have
cost you twice or thrice the price =20= of buying a small amount of good
quality hydrazine hydrate. Good luck, Jacob On Feb 28, 2005, at 7:53,
