My calculations say:
Start stirring, add, in this order, to a 1L rb flask:
1" magnetic stirbar
89ml dH2O
42.9g Na2CO3 (810mmol base)
61.6g (NH2OH)2.H2SO4 (750 mmol hydroxylamine salt)
Allow this to stir until uniform, then add:
461ml MeOH
600mmol phenylacetone (slowly)
Reflux 1.5 hrs on water bath, then add:
240ml cold water
Move to freezer for 1hr. Suction filter, wash oxime with up to:
1200ml water
If you don't have either sodium carbonate or hydroxylamine sulfate, you can use one of these instead:
110.2g NaOAc.3H2O
52.1g NH2OH.HCl
If you don't have 95% EtOH, substitute with MeOH and it will work fine as well.
The above procedures have been tested by SWIC (they are not just "in theory" calculations), and worked fine!
Btw, the H2O quench might not dissolve it, but the H2O wash certainly will. I've always seen that "slime" of sodium sulfate, and I think it's mentioned in other threads as well... but it seems to dissolve away no problem...
