Title: Problem with Rochelle Salt
Post by: eve 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 ??

Title: washing out rochelle salt

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.
