Just fucking buy it. No don't do that with the sieves. If the sieves work, they work, if they don't, they don't.

You can use anhydrous copper sulfate (white) and it'll turn blue in the solution. Keep adding copper sulfate until no more turns blue.

Or you could just buy anhydrous ethanol which is often cheaper than anhydrous copper sulfate and molecular sieves.

magnesium sulfate won't take it all the way to 200 proof but it will get you slightly past azeotropic ethanol.

Sieves are easy to use; you don't even need to distill anything, and they can be regenerated by simply putting them in a pyrex flask (or improvised equivalent) and heating with a torch while shaking them up until no more condensation appears at the mouth of the container. They will absorb a little water while cooling but it's not much of a problem unless the humidity is super high or you need ABSOLUTELY dry ethanol. If in doubt stick a coffee filter filled with another drying agent (like mag sulf.) in the opening while it cools, so any air entering is relatively dry. Either way, the sieves will still make ethanol way drier than using MgSO4. They do take a while to work, but all you have to do is dry them out, dump them in, let it sit a few days, then filter off the sieves.


Opium Column Chromatography by Bombastus Werrywag - Tue, 11 Jul 2017 21:56:30 EST ID:QGxEeR56 No.78746 Ignore Report Reply Quick Reply

Without calcium chelation, this is the best way to achieve pure morphine from a layer of puddy or otherwise concentrated poppy residue.

A mixture of 9:1:1 DCM Methanol Diethylamine will produce an elution of reticuline impurities at 0.7-0.9, codeine at 0.45, and morphine at 0.2. Other opium oils either elute at 1 and heavier, coloured oils will not elute at all (or under 0.02).

Running this column simulation once gave me morphine as light brown needles which drew in moisture and became wet after 3 hours. The second time, morphine did not completely come through as shown on TLC short wave UV light as what I expected to be high amounts of meconate salts along with insufficient methanol miscibility. This was solved by adding an additional 1 equivalent of methanol thereby moving the morphine. This gave darker brown crystals which again absorbed water after 3 hours. Full morphine elution towards 100% in a gradient column gave 2% of brown oils. This potentially allows a column to remove codeine and oils and a methanol flush to remove the morphine with a 5-10% heavy oil contamination.

Will update this thread with more conclusions and projections.

Mesylic acid? I'm pretty sure methanesulfonate isn't nucleophilic enough to attack an ether. Most demethylations I'm used to hearing about use hydrobromic acid or pyridine hydrochloride. Hydrogen iodide is very effective but also expensive.

>>78831
you can use Zn powder / hydrochloric acid to reduce terminal nitrostyrenes like for mescaline; it's really just nitropropenes that are "hard" to reduce (although Al/Hg licks it)

this is basically impossible because psilocin is very unstable and so doing ordinary unqualified idiot garage chemistry on psilocin will turn it into useless polymers. if you freeze-dry the mushrooms, grind them up, extract into water under nitrogen, hydrolyse with alkali for a few hours also under nitrogen, extract into chloroform under nitrogen, and treat this with acetic anhydride and pyridine under nitrogen, maybe you have a chance. but you've probably not even considered that the whole rxn has to occur "under nitrogen" or that e.g. reflux in acid as one dumbass said will tear apart that indole like a dog playing with a soccer ball. furthermore it's not even any more potent than what you started with so you're wasting mushrooms. and if you meant to do the synthesis from scratch, you have absolutely no chance so just read the tihkal entry and sob quietly about your inability to acquire 4-hydroxyindole, oxalyl chloride, dimethylamine, or LAH.

Can you use a dehumidifier to dry 0.5-1liter of liquid ketamine or would it suck up some of the ket as well (I know of the other methods)

How do you flavour ket.Do you just simply add in some food flavouring liquid while you are drying it ? How do you workout how much to add into it ?

okay, thats fucking retarded but okay. i dont recommend throwing vanillin into your nostrils but whos gonna stop you.atleast its not menthol

you could theoretically dry your ketamin by placing the solution next to a dehumidifier preferably in a airtight container, but its going to take much longer than just throwing it in a glas pan and carefully heating it. then just scrape it up, grind in a mortar and slowly add small portions of pure vanillin - not fucking baking aroma - and keep grinding. sample and repeat until youre either cant feel your face anymore or are deep in the flavour town hole

Well giving the pH value of anything assumes it's in a solution and since pOH and pH exist in equilibrium one can be calculated from the other which is why we just use pH. And I get that it forms a buffer I'm wanting to know chemistry specifics because I've been googling for months with no clear answer. Nobody cares how it works they just use it. I understand it has something to do with the controlled release of H+ and OH- in some sorta cycle.

My level in chemistry is like 1000 level course in college plus more reading on my own. I understand how cyanuric bonds to the FC to keep it in the pool. I'm fuzzy on the carbonate buffering. pH is wacky in a few places and I'm trying to pin down a cause and also they may have me train employees and I like to know everything and assume others would as well instead of having to dig for the information like me.

I just read on circlejerk that some trees can reach 100ft to 300ft in a matter of a few years, if this is true why dont we just farm trees instead of cutting down rain forests?

I mean it seems possible, you might have to stick to certain types of wood but still, on top of that you could plant a shit load more trees to help with climate change.

I'm no expert though, just some thoughts.

How important is genetic diversity?

My mother and father are very far removed, my father being mostly Slavic/Eastern European, and my mother being mainly Celtic. My paternal grandparents are also very distant from each other, my paternal grandmother being Russian/Belarusian, and my paternal grandfather being Ukrainian and Turkish. However, it turns out that my maternal grandparents are third or fourth cousins, so I guess there is some inbreeding there. Realistically, what are the impacts of this?

if it is methanol, it can be removed using fractional distillation.

if that term is unknown to you then research is needed to not kill yourself. if you don't know, you likely do not have the skills required.

i do not advocate this method. try brewing your own alcohol. it is stupidly easy once you know how to do it and you can make 18% alcohol for like $1/liter

an easy way to do it is to get EC1118 yeast and add it to water that has been boiled with the sugar.

my equation based off of experience is [desired alcohol content]x20x[final volume in liters] = [total grams of sugar needed]

for example 21L of 18% alcohol would require 21L*20*18=7560g of sugar.

you can add fruit or juice or whatever to make it taste better. research brewing for the rest of the details.

18% is probably a bit high without the turbo yeasts, the highest % i've managed was 15% with a very good yeast. But you can get up to around 30% with freeze distillation (fractional freezing)

To my knowledge, methanol doesn't form an azeotrope with ethanol. Anhydrous samples can be distiled and collected that way. If it's 30% methanol, you can just distill out 30ml of a 100ml sample and it should be fine once the temperature reaches 75C

>ammonia, toluene, methanol, acetic acid, hexamine
most combustion products and starters produce or contain these. combustion makes them different

Hi there /chem/, there is a website where you can download a lot - and I mean thousands - of science textbooks (all categories) for free. Most of them are in .pdf files, but there are a number in the .epub, .mobi, and .djvu formats as well. I uploaded a small selection of what I've gotten at Zippyshare, here:

http://www44.zippyshare.com/v/3IAuapuz/file.html

They cover the hard sciences and run at about 135 MB for the .zip file.

The website is here:

and please read their "Letter of Solidarity," here:
