used a bad solvent - any way to speed things up

[messybeds]

Hey guys,

My first extraction was going well, unfortunately ive used mineral turpentine (which is basically a mix of C6-C10 alkanes) which i thought you americans would call naphtha. I looked up the MSDS yesterday and it has a boiling point of 140-200 degrees celsius which explains why the evap is going so damn slow. Is there anyway to speed it up (there is still 2L+ with a huge amount of crystals already precipitated out)? for using baking trays to heighten the surface area as well as hot water baths (My sister yelled at me) and using a fan (and the aussies sun which is around ~25 degrees most days) with a muslin cloth over the top to evaporate.

I have 1L shellite (very pure heptane or octane) and 2L acetone which both aren't anywhere as cheap and i was saving for the purification steps. Is there a way to lower the boiling point/speed up the evaporation process further than i have already

HELP?!?


** help has been give. will freeze precipitate then recrystalise from hexane

FREEZE PRECIPITATE goddamnit!! Then recrystallise from heptane to get rid of hydrocarbon residues. You can re-use solvents after freeze precip. This is basic stuff that can be found on this site with a minuscule amount of effort, btw. Speaking of which...

No synth talk allowed.


P.S. I'm not American!

P.P.S. Welcome to the Nexus!!

P.P.P.S. Your evap procedure has now concentrated relatively more heavy solvent residue, so whatever happens you'd better do a recrystallisation. Thing is, heavy naphtha is actually really good for freeze precip and I quite like it for a couple of reasons.

more yelling at for using chemicals in the freezer. will try again while they are at work.

any other help as to how to make a suiable filter from household products. currently made one from a cotton tshirt (the type you iron) and a collender. will this work.

Also what temperature should i be trying to get the naptha to before i try to filter

Your filter seems good to me. The freezer should be well below freezing temperature. Unfortunately, you should keep it in there for a full 24 hours.

We do not condone extracting in environments with other people who will not approve around.

its not the extraction that bothers them its having napha in the fridge next to food. ill keep it there for 10 hours and hopefully it will have precipitated the majority of DMT. ill save the solvent for the next extraction

I see. Stay safe, and place a lid on top of the container. 10 hours may or may not be enough time to precipitate the goodies depending on your freezer.
