Problem with Rochelle Salt
« on: November 17, 2003, 10:26:00 AM »
SWIM accidently added the rochelle salt into the 2,5-dimethoxy-nitropropane when doing the washing. Now all the oil is cloudy.  :(  What to do now ? Is it all spoilt ??

Dissolve the nitropropane in a non-polar solvent, wash out the rochelle salt with water followed by brine, then dry the non-polar solution over MgSO4 and evaporate the solvent. Now your nitropropane is back.
