What is the difference between comerisal heptan with formula C7H16 and heptano n-PRS? The first one cost 10$/L amd second one is 50$/L.

Level of purity. The 'heptano-n PRS' is pharmaceutical grade n-heptane. PRS seems to be a Spanish pharmaceutical designation (at a guess). One website I've looked at is selling litres of the commercial grade for 6,78 €, whereas the PRS grade is 72,97 €

I note that the cheap stuff comes in a PET plastic bottle, while the PRS is supplied in glass.

I think we speek for the same web sait.Do u think the cheep one will be good fpr extractions?

It would certainly be more cost-effective than the expensive one, but cheaper and more effective solvents are available - have you moved to Spain? Weren't you in Romania? And I seem to recall you had difficulty finding naphtha. I'm unable to comment on the availability of solvents in either country (although that website seems quite good!)

Whatever, a heavier hydrocarbon blend would be more effective for extractions but you'd still want to be looking at the heptane for recrystallisations - unless you decide to use a different method of purification.

Yes,I had mooved to Spain.Napht is dificult to define what is inside.There is diferent types of naphta.Heptane seems good because u can make very poor dmt with it but I am not shure if the cheepr variant is good.Anyway 7-10€/L is nothing expensive for me.Can u make a look and find other solvent good for extractions in the websait.- manuelriesgo.com

Check CAS or EG number on the bottle and google it.

Cas:[142-82-5] is this good,couldnt find info in google for extractions

There's quite a range of solvents on that website and many of them would be useful depending on what one intended to extract!

Ok guys,I don't want to start this again but please understand I am still noob want to learn and tryin to do my best.I still didn't extracted DMT by myself but I want to become profesional in this.By profesional I mean donthe job by diferent ways and understand what I am doing same as my other hoby planting marijuana.Plese help me understand better the theory befor I stard because I am very short on tome and money and want tobdo it faster.
I have the bark the electronic PH meter and the 0.01sale.
I want to use the vovin tek stsrting with small 50 gr extraction.My idea is to get as mutch clean DMT without losig yeld.By losing yeld I mean left some NN-DMT in he leftover.I want all NN-DMT out probably some other alcaloids but nothing of fats and red gooSo after I readed a lot and used the search button I am in the choose of solvent.
People say DCM is the best because it pulls more.I don't want to get orange goo that couldn't be disolved back in disolvent.I think to salt out with acid water and then basyfi pull wih heptan.Is that ok or it is the same as pull direct with heptane?As I understand DCM will pull all DMT and something more like fats,so after salt out I will get all the DMT and let the leftover in the DCM?Am I wrong?

Can I get the same amount of DMT only with heptane and do more pulls?How mutch pulls/amount need to do on 50 gr using Heptane?

Plan B is pull with DCM evaporate and recristslise wih hexane,witout salt out and Heptane pulls,should it work or it will be very undisoluble goo?

Can't I just recristalise with heptane and no usin hexane I think the diference is only the boiling point so in hexane he cristslnwill crash faster?

Can I basyfy the filtered mimosa tee direct with lee without making lee solution what is the diference?

What quality DMT is good for changa,do I realy need to make white xtals?

Can my Vanguard PH meter be used in hot aceti water?

Thanks for responds in advane ane perdon my bad english is more like typing mistakes due hard working day.Guys I am soo close to do it.

Just use Cyb's Max Ion tek! If you have MHRB there's scarcely a need to defat so the whole acid cook is a bit of a waste of time and resources. Also, I've noticed that hot acid cooks on MHRB pull loads of tannins which just mess up any filtering unless you want to settle and decant for about a week's extra wait.

I'll answer the questions anyway:
Yes. You might as welll do that. The rest of this question has been answered multiple times on the forum alreasady and again quite recently. I'd do 5 pulls of 23mL at blood temperature, but that's probably just me.

Don't bother with the DCM, it's more prone to emulsions and can react with the DMT to form impurities.

Don't use hexane. Heptane is the recrystallisation hydrocarbon solvent of choice these days.

You can use solid lye/caustic soda/sodium hydroxide directly although it's more prudent to dissolve it in some water first. It can get VERY hot.

I hope you have eye protection goggles already. These REALLY are a MUST!

Goo is fine for changa. White crystals are largely for show (They are fine for changa as well, of course!)

pH probes are designed to be used with acidic liquids. Look at the instruction leaflets that came with your pH meter to correct your readings for the higher temperature.

Take care, be well.

Yes it seems interesting but can I skip the 8 hours heat bath ,this is ery dificult for me.Vovin tek use 3 x 45 min bath.Also he say that PH shouldn't go under 4 and up 12.Is this true?
I readed the both salt teks and the only thing I don't understand is why we don't selarate the plant material befor we use the disolvent.Anywahy it seems very simmilar with the vovin tek with the salt difference only.

hi there!
in spain you can easly find zippo lighter fluid... why don't you go for that?

Well friend In all the word u can zippo fluid isn't it so expensive ?! I think it is b
Better to buy heotan at 7€/gr.

STB works well on MHRB slurry because the lye breaks down the plant cells. The 8 hour hot soak isn't strictly necessary, you can just leave the basified mixture somewhere safe overnight and then do the pulls when you're ready. Vovin's pH limits are not strict, IMO.

Heavier naphtha pulls better from the basic slurry but it's still good to recrystallise using heptane.

It shouldn't be that difficult to find this stuff:

Why the rush, OP?

These things are well known to take some time until some sort of perfection is achieved. Of course, speeding up the processes will result in something, but the rule of thumb around here is that patience is key.

There's another feeling I'm left with after reading your posts, apart from a reckless type introduction to the board , and that which I'm left with makes me point out to you that I hope, and for the greater good, that you have your feet in the air and head on the ground... oh, it was supposed to be the other way 'round... your feet on the... ah, you get the idea.

Just some food for thought. Hobbies are nice as long as the professional does not turn into profession. See, there's a thin line between the two terms and they usually can degenerate even more. Depends a lot on one's intention, though.

Nice and all to see you deflate your previous personal opinions on the forum, but remember... don't rush it.

I wish you the best of health and safety during your novel endeavours, whatever they may be.


P.S: For the reading experience's sake, I'd at least try to hit the preview button before posting. Spell check is also a thing, but maintaining a clean style of typing (doesn't have to be immaculate) really helps a lot on the readers side... just saying that maybe you can try?

Well very good actualy u found in reloymerlin a nafta.I couldn't imagine how they call it here in but ya this is nafta and the cas nuber says : DISTILLATES (PETROLEUM), HYDROTREATED LIGHT please confirm this is fine.Actualy this is product made i Germany on of the places with the best profuction quality all lver the world.I still didn't have the time learn in advanced chemistry what are those carbones but I will...Confirm if u can and will go for it.Reciclising with hexan I think.And the other site I already know it but they don't have detalied info for the dislovents..

@downwardsfromzero can u please explian how many 50 ml pulls u need,firzt it says 4x and put in freezer and after that it says *Repeat Steps Six and Seven - 4 more times*
(So 5 pulls in total).It is like pulls 4 times and freeze and then do 5 more pulls freezs wih 4 x 50 ml?Sory it is bad explained.I am talkin about the 27% cybs hybrit ATB "Salt" tek
Anyway I coudn't understand adter 5 times reading it why is called 27% tek.

Hey, mate! Why don’t you invite downwardsfromzero over at yours so he can extract for you? It’d be a helluva lot easier than trying to spoon feed you online while you spit out everything he teaches you... seriously, he literally walked you through everything you need to know already, the teks are foolproof written in plain black and white text, some offer the luxury of pictorials too.. but somehow it still doesn’t suffice.

Trolling is baad, bionecrose

Spain would be very nice. I hope it's sunny, the weather's pretty much constantly shit in my part of the world.

In the interests of being nice, here's a very brief (and final) outline of what to do:

MHRB=>add water=>add lye=>stir=>add (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>add more (5.23mL) naphtha=>stir=>remove naphtha=>fall over=>put combined naphtha pulls in freezer=>fall over=>return after 48 hours=>remove naphtha container from freezer=>quickly pour off naphtha into MHRB sludge=>air dry crystals in frozen container=>fall over=>fall over=>fall over=>fall over=>fall over=>ask someone else

Well no need to make joke from me.I couldn't understood because it says 4 pulls weiting each pull three times to separate. Anyway big problem with the extraction heppend and I starting new threed for it.
