Title: sulfuric acid reaction with formic acid
Post by: mrspock on August 22, 2018, 11:28:44 AM
I need to make sulfuric acid react with formic acid under a fume cupboard certainly. Do I need to cool with ice water jacket the pot with the acids to reduce to zero the release of formic acid fumes?

Formic acid is not the problem, but an other poisson gas? Which is it?

Carbon monoxide will not affect the subject researched since it in not alive. I am worrying about corrosion and similar effects if hot liquids make formic acid evaporate.

Curiosity question

What concentrations of
sulfuric acid and formic acid
do you intend on using.

H2SO4

O=CO

Is there a particular reason you need to do it on such a large scale?

I need a proper concentration of carbon monoxide for at least an hour and the closed area with the device under research observation is 60 cubic meters large.

Why not get it in a gas bottle?
