I was reading through Kash's LSA extraction tek and I noticed that there are quite a few solvents, as I'm sure there are with many other teks. I feel stupid for asking, but I don't know a lot about chemistry and the presence of so many chemicals that are normally used as paint thinners is concerning to me. Could someone alleviate my concerns? Does everything harmlessly evaporate?

how about ethyl acetate?
it' used as the mobile phase in gravity [ion-exchange] chromatography

benz, i get the feeling that you might as well have spoke latin to the poor bloke.benzyme said:
and wolf, all of the teks here on the are 110% safe if you follow the instructions closely.
aww dammit..
sorry, i forgot about that part. I read it, but wrote a response that didn't reflect
that I read it.
ethyl acetate is relatively non-toxic, and not as flammable as other solvents. just don't smoke around it.
It has a somewhat floral scent, and is available as non-acetone nail polish remover, or kleenstrip MEK substitute.
it separates as a top layer when extracting from base.

Thanks very much for your quick responses, guys! I certainly wouldn't have understood your original answer, benz, so thanks for clarifying. I feel terribly illiterate when it comes to this sort of thing, but hopefully I'll be able to gain at least some general knowledge of chemistry through experience.
And thanks to you, Parshvik, for giving me a bit more peace of mind.

it becomes much more understandable once you have already done it, that is for sure.wolfstine said:
I ran into a dilema concerning this topic and discussion. New member, long time "peruser". Concerning Kash's tek, the one Wolfstein is refering to, I'm wondering what could be the cause for there to be no sign of residue in the final evaporation dish. I followed the teks detail and only improvised when defatting 4 times instead of twice, while making LSA citrate solution agitated for 30 mins each fraction instead of 10 minutes, took a long time adding ammonia dropwise while stiring defatted LSA citrate solution to basify, took time adding Toluene (approx 25 mins during first pull of Toluene from basified aqueous solution(done after got the ph right after adding ammonia dropwise)), used litmus ph strips, the humidity was high and temperature hot during procedure and evaporated outside out of sun. Only the finest glass was used. what could be the cause? All proportions were followed.
Basically the procedure uses
-3 Anhydrous Acetone filtrations (3 hours of agitation between filtration), discarding seed pulp after 3rd filtration.
-All 3 filtrations then evaporated fully to a fine layer of crude LSA extract that came off in thin semi translucent brown sheets once scraped.
-After collecting scrapings, citric acid was added to distilled water to ph 4 (shooting for 3-5) then added to crude extract. 30 minutes in-between filtrations of that solution left me with LSA citrate that still had to be defatted.
-Then, defatted with 4 VM&P naptha pulls (separating layers with seperatory funnel saving aqeuous layers.)
-After all aquous layers combined, solution was basified using drop by drop ammonia. I tested ph with litmus papers, however it took more than expected (dropping drop by drop for 45 minutes while stiring with glass stir rod. (Perhaps that was the mistake?) (thhe small amount refered to in the tek didn't seem as small as expected to me while trying to get the ph right, could have destroyed LSA) Finally, I knew it had been based enough when the color of solutin changed from light yellow to orange to algae green(this happened while dropping for 45 minutes in chronilogical order attempting to reach ph) and ph paper said 9 just before solution turned so green. If it turned blue, the tek states it would do that if based too much, however it only turned blue after it had been left aside to sit after extraction was fully completed and basified aqeuous layer had been pulled of all alkaloids with Toluene theoretically.
-Toluene was added quickly (after 45 mins reaching ph with ammonia) and agitated for 20 mins, then separated using seperatory funnel. After 3 Toluene layers, the fractions where evaporated. The problem came when I checked the dish and there wasnt any residue of any kind or anything. My educated guess would be taking too long to reach ph 9 while basing defatted LSA citrate solution
Any wisdom would be wonderful. Peace.

You could always try the other LSA tek for starters then jump to Kash's Advanced LSA extraction after you get your legs under you.
I still look at the Advanced tek and dont want to use it because of all the steps and I've worked with LSA, DMT, Harmalas and Mesculine teks at this point it time.
Keeping it simple on the upfront will build courage for further work.
:thumb_up:
someone already got to see this simple method here and know it would work? and could cause the desired effects without causing nausea or stomach aches?

For the layman: nonpolar solvent also = Zippo lighter fluid.
