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.
