Bayer villiger oxidation solvent dilution question.

[Jack]

A research paper oxidizes some alpha beta unsaturated ketones to vinyl acetates, and the amount of solvent used is alot due to them doing it on such a small scale. here is the method;
What ratio would you imagine would be appropriate with regards to ketone to dimethyl formamide in scaling this up 700 times.
ie 0.5 mmol to 0.35 mol. or 50ml of ketone?

How do I separate the vinyl ketone from the dimethyl formamide without using toluene and a vacuum distillation.
