Hexane or perhaps Acetone?

[Deranger]

Hi folks!

I´ve been reading about this and that and am hopefully looking at my first extraction in a near future.
The tek I´m planning to go for suggests naphta as solvent, simple STB, basify, extract, evap, kind of.
Anywho, in the following discussions regarding this tek people also mention hexane as a neat substitute for
naphta.
I just happened to stumble upon rather cheap hexane, jolly good, thought I to myself.
But, truth be told, my chem-skills are in their infancy and hence I need to check up on every little detail.
This particular hexane contained, if my memory serves me right, 92% ethanol, 5% methanol and 3% kerosene and
had a very distinct light pinkish colour to it, somewhat like watered out raspberry lemonade.
Could not find anything else in the table of contents except the above mentioned, but was qurious about the colour.
As I understood, naphta comes in all shapes and sizes, is the case the same with hexane? I supposse the ethanol
and methanol would evap just fine, but will that dash of kerosene make my precious spice all but precious?

Maybe I should take this on some completely other forum dealing with petro chemicals or whatnot....
Sorry if this is malplaced.

Secondly, there was also acetone on the shelf. I have not seen acetone mentioned much at all, more than on the odd speculative
occasion. It sure has tremendous value come evaporation-day, but will it pull the alkaloids from the basified mixture?
Im thinking the acetone is 100% acetone and it evaps like there is no tomorrow, meaning like, is there any residue left
at all when acetone evaporates? Now, what little I've learned about acetone, impurities comes in the form of water, so
even if its crap acetone the crap is water and would by a wild guess bind to the water in the basified sludge during
the pull, or not?

Thanks you all for a great forum, I´ve merely sifted through it as of yet, looking forward to dispose more of my time
here.

Cheers!

If its 92% ethanol, 5% methanol, and 3% kerosene its not hexane. Hexane is a different molecule than ethanol, methanol, or kerosene. Hexane is a non polar hydrocarbon, ethanol/methanol are alcohols, moderately polar at that.

Acetone is unsuitable for an liquid based a/b extraction being that its miscible with water. Just like you couldn't use any other alcohol/ketone like isopropyl, ETHANOL, METHANOL, because they are all mixable with water, and will not separate like an oil/water scenario.

However, for dry teks, using lime where no water is present during your pulls, acetone works very well. SWIM just finished converting all his impure mescaline fumarate to clean hcl's by mixing the fumarates with lime/water then drying. Pulled with acetone, then added 10% hcl distilled water to the acetome pulls and evaporated. Nice clean xtals were the result after one acetone wash/water recrystallization. You could do this with mhrb/cactus powder, etc. Freebase alkaloids are very soluble in dry ketones/alcohols most of the time. At least the good molecules are :d.

Thanks, I´ll take a look into the dry teks. Also I saw I´d misinterpreted A/B - STB is what I´ve been thinking of.
(by my logic A/B was "straight from point A to B, or from state A to state B... :-D

But that does not change the fact that I by some peculiar reason found bottles labelled "Hexane" containing a coctail of
stuff that obviously is not hexane. Well well, what do you know, live and learn.

Great many thanks for the heads up!
