I have a nice batch of MHRB paste a la q21q21 tek.... and i want to make the NPS pull... i got some FASA, DCM and toluene...

has anybody used fasa to precip crystal from DMT??? i have searched a lot... ive seen others make the same question and get no answers..

You got some FASA? You know fasa = Fumaric Acid Saturated ACETONE.

Pull with tolulene salt out with FASA. Dcm is a good solvent but much less safe & harder to correctly dispose of.

Next time around drop q21q21 & go for cybs tek. Much less messy & alot simpler + 2% yeilds are the norm.

Cybs tek can be followed with tolulene in place of naphtha. Just salt out once you've collected the tolulene pulls.

Quote from science madness administrator:

How much chloroform do want to get rid of? If there only is a few 100's of ml, then take an old towel or a big heap of paper tissue, put this outside and pour the chloroform on the towel and let it evaporate. The towel can be thrown away with normal waste. Do this on a windy and dry day! Chloroform disperses quickly in the atmosphere and soon is hydrolysed to harmless chemicals (CO2 and chlorides). In this way I get rid of small amounts of organic volatile chemicals, usually with quantities in the 1 ..5 ml range.

No, it unfortunately does not work...don't know why though.

How can i dispose of it correctly??? im planning on evaping it on an open air area... sounds good?



I guess that after i make this extraction I can play a little with the "spent" paste... maybe drying it then rehydrate it with salt water and add the lye... then pull like cybs tek to get an extra yield'?? gonna try it and then report...

i really did not do an cybs max ion because all my big glass containers broke and i could not handle an aquous phase extraction because of this... besides i have seen q21q21 gets cleaner looking xtal

thanx a lot for your patience with my stubborn head concombres and infundibulum

evaporating it in open air is perfectly fine. It will break down into things harmless to the environment which already puts it a tier above xylene.
