Dear sirs,
according to what is written on Fieser & Fieser, vol 1, pag 748, NOCl may
be produced "passing dry HCl into sodium nitrite: NaNo2 + 2HCl -> NOCl +
NaCl + H20."
I am interested in nitrosating a substrate which shows to suffer hydrolisis
in acid conditions, say pH < 4. I thought that fuming HCl from conc.
acqueuos HCl could be passed into conc. H2SO4 under a slow stream of inert
gas, say nitrogen. The gaseous mixture may be driven to some glass piece
containing the salt, ending with a capillary into the solution. This may
eventually be buffered to prevent to turn the solution too much acidic.
Anyway, i don't know if this may be good enough.
Do you have any suggestion about a better apparatus i could use?
Thank you.
andrea.
