Hi all

I have a question about separation of dicarbonic acid and its monoester:

HO2C-(CF2)10-CO2H (1)

HO2C-(CF2)10-CO2Me (2)

Could you suggest their separation method?
Does anybody have experience with similar problem?

P.S. Monoester+acid are formed by partial hydrolysis of the corresponding
diester (3), then silver salts of compound 1 and 2 are formed and 3 is
washed out by organic solvent. Then silver salts are acidified and we have
soluble in organics mixture of 1 and 2.

MeO2C-(CF2)10-CO2Me (3)
