SWIM had a similiar dream, only that in SWIM's dream, no vacuum was used to distill the toluene. After the toluene was stripped off, all under atm lower, a junk of brown crystals fromed as well as oil.
Tried to isolate the formed crystal bfore adding muriatic acid, kept them aside. These brown crystals just wouldn't dissolve in boiling IPA, thus could not do a recrystallization....... bad dream.
The dream went to to show that ethanol was used to dissolve the oil, 5N Muriatic Acid/IPA(dried with silica beads) was added to the oil to form crystals.
The dream went on to become nightmare when muriatic acid was added to the oil(dark colored), some crytals formed and washed with acetone, and failed to dissolve under dry boiling IPA agian. They seem quite white, but with a lot of reading, SWIM thought that they were not pure. Anyway, SWIM dreamt on with FOAF and being stoopid to try the product and no effect was noted even with 1g dosage(the salt tasted very salty, where SWIM tested before some very nasty and bitter salt which gave good feeling). This was really a nightmare, in the process broke a 1L RBF with 50g ketone loss, not to say that another similar dream happened where no crystal was in sight at all.
Can any experience bee tell SWIM that what color at what stage should SWIM expect in the Barium's wet dream. please?
