Dear readers of Orglist,

as previously stated (Kresze et al., Organic Prep. and Proced. Int., 19,
1985, pp329-426), "the reactions of oximes with elemental chlorine or
bromine are usually carried out in aqueous or basic solutions".

I need a buffer for an acqueous pH value of 5.5, unreactive and stable
versus chlorine gas.

Any suggestion (better than CH3COOH/CH3COONa)??

Thank you in advance,
Andrea Giordano
