Heavy naphta ok for extractions??

[AIRDOG]

Hi ive beed doing several experiments with different teks.... and i have learnt that i like dry teks better... i had never used naptha since i could not source the stuff...


at last i found out someone who sells it for the dry laundry industry...

the thing is i bought some and distilled it to find out that it only has a small fraction of light naptha in it... and the majority of it is heavy naptha with boiling point near 180ºC

I have read here that one should aim to use light naptha...

I wanted to use this for re-x and to clean salvinorin extract, but I bet this stuff will take forever to evap...

is it advisable NOT to use it? or im in the clear, what should i be expecting with this stuff...

Do an evap test with a bit of it in a glass dish and see... Then you can decide for yourself.

Generally heavy naphtha is not recommended because it will take ages to evap. Considering it does eventually evap, it should be fine, but make sure you have your product fully dry after evapping.

If you are distilling, why dont you just save the lighter fraction and use that instead?

I know i could just do that, but its negligible amounts... like 20 ml per litre of solvent...

I would need to buy a lot of the stuff to get a decent volume of light fraction... it would be costly as hell

Did you look for low-aromatic (ideally non-aromatic) and non-chlorinated paint thinner? These are often reasonably low boiling aliphatic hydrocarbon solvents.

Since you have a still, I encourage you to distill all solvents before using the first time. Another advantage of a still is that spent solvent can be cleaned and reused.

If you cannot find a better naphtha than what you have, you can extract the basic tea with the heavy fraction, then back extract that with white vinegar and finally base and extract with the light fraction. When you freeze precipitate the dmt in the light fraction, the crystals will dry much faster. The second part of this double A/B involves smaller volumes, so it might fit the ratio of heavy and light fractions in your naphtha.

Good post by pitubo.

Even if he doesn't have enough light naphtha to pull off the mini-A/B would multiple mini-A/B's using the heavy naphtha clean up the product appreciably? How about with DMT?

yeah thanks pitubo! i have been doing it like this since i bought the still... wich was aquired precisely with this in mind since i cannot get quality solvents in my country...

all of them are bulk industrial grade, now with the still im able to do the things more confidentrly...

i distill the solvent before each extraction to nullify any plastic that could have leached from the screw caps of my bottles since they all have a plastic seal, I guess the fumes of the solvent (even when capped condense on the cap and then fall out making plastic contamination... the seals wear out rapidly... now im placing a layer of aluminum foil before capping them to nullify this

this heavy fraction of naptha really takes a lot to evaporate... I was able to evap it putting my flask in a hotplate for a salvia cleanup... luckily salvinorin is very good at withstanding heat, i got the best extract i had made...

i used to make some terribly greasy gooeish extract before
