SWIM did Noman's STB on 50 g of MHRB. For some reason the yield came out very dirty. She combined 2 first pulls and tried re-xtalisation. SWIM used 15 ml of heptane for it but after an hour in the fridge she got about 20 ml of dark yellow rather homogeneous jelly. After half a day in the freezer SWIM noticed certain amount of crystals lodged in the mass of brwnish goo.
SWIM read in a lab manual that re-x does not work well on very dirty mixtures. She decided to try an A/B on goo with crystals. Browsing the forum she did not find a description of an A/B, modified for processing dirty STB yields. She suspects that there is no need for 3 acid pulls.
Any suggestions?
