HCL 37%

[TheVacuumGuy]

Hi all,

Could anyone provide me with a "use case" for 37% HCl? i searched for several days and came to the conclusion there is none, really.
However, it is asked when ordering this....

needless to say, disclosing the real intentention would not be a good idea

How can we use a round bottom flask? I looked around the Forum several days but didn't find any application for that. Please, help!

Sharp!

luckily these don't require an end-user-statement.

Let me rephrase the question:

What i'm looking for is a purpose/use-case which would justify 37% HCl over 30% HCl , that is: what procedure really needs 37% HCl, where 30% would not suffice, or would cause quality issues.

This 7% isn't so big difference, to be honest. I don't remember such syntheses where exactly 37% HCl is taken (talking about clandestine syntheses).

Hmm. I might just go about concentrating the 30% stuff by dripping it into sulfuric acid and lead the gas to an inverted funnel setup in a beaker containing highly chilled hcl 30%, setup in an icebath.
The problem is that it is a lot of work and messy (esp. cleaning up) for rather small volumes
