Prepare the freebase using sodium carbonate or potassium carbonate. Dissolve in diethyl ether, (NOT starter fluid, its full of heptane and oily shite)
IPA might well wet the fag and make it a nasty soggy mess, I imagine, if it is not dry. And I mean, very dry. Not certain it will, but certainly not impossible.
Not done this, although thought about it. It should work, It is a phencyclidine analog (of eticyclidine, more strictly speaking) and PCP is often prepared in vials, dissolved in ether. Shouldn't be too hard to dose either, really, thinking about it. If one dissolves a given quantity in a given volume of ether (note-petroleum ether, aka naptha, is NOT anything similar to diethyl ether, pet ether isn't even an ether, its basically light petroleum distillate fractions mostly), and that given dilution, then soaked onto the fag.
I did try vaping the MXE in the form that it came in from the supplier, as purchased without preparing a freebase, and it really didn't work very well at all. I do not know what form it is in, I am pretty certain it is a salt, and I assume the hydrochloride, being pretty much the most common counterion for many pharmaceuticals, and would make sense, ket in the form compounded for vetinary use is the HCl salt also.
I'm trying to find out at the moment. A bump was placed on foil, and the usual technique applied, attempting to inhale through a rolled Al foil straw. Result was harsh, and vile, and without success. It definately needs to be based before smoking, if it does turn out to be suitable for smoking, I believe in the freebase form there is no reason it shouldn't be.
Should be getting more MXE soon, I shall have to test it. I think I shall freebase it as described, or possibly experiment with NH3(g) bubbled into THF, on a small scale, dissolve a sample, sufficient for spiking one fag in a little dry THF (no ether hanging about but enough THF) Aside from oral and sublingual (unless licking residue from transferring powder, wiped from scale, wiped from rim of bag, et cetera counts) its the only obvious route I have yet to try.
Tell you where one CAN get some 2-propanol, although it is not cheap, IPA is usually cheaper than a syphilitic gutter whore, but, there is usually water content, which of course will not evaporate and will just result in a soggy, designer phencyclidine-spiked mess. Alcohols can be dried, molecular sieves, of the right pore size can do, as can for instance, distillation over calcium carbide (caution, releases acetylene gas as the residual water content reacts irreversibly with the carbide, and acetylene is highly flammable, and in the right concentrations in air, an explosive mixture is formed, sparkless switches on the heating equipment for the flask are a must!)
Mol. sieves are the best bet I imagine for drying bought average IPA, reusable if dried by heat, as not everybody has the equipment to safely perform a distillation. Dry isopropanol, could be obtained in smaller quantities, at a fairly expensive price, as I said, from electronics suppliers. 2-propanol, very, very pure is used in electronics manufacture, in an aerosol spray for removing water, and other soluble rubbish from electronic circuits, as water is completely miscible with IPA, and IPA is volatile enough to efficiently carry trace H2O away. I would use electronics grade IPA if I were the average bear with some MXE and wanting to attempt using IPA to dissolve methoxetamine freebase. Going from my quick and dirty chasing from foil attempt, the form usually supplied is a salt, I would hazard a guess at the hydrochloride, but that is just a guess, based on its safety and wide use as a counterion for forming salts. Does not vaporise properly at all as it is.
Methoxetamine base should be soluable in nonpolar solvents. Diethyl (not petroleum 'ether') ether is used for PCP, THF (tetrahydrofuran) is very similar to diethyl ether in terms of physiochemical properties, as a solvent. More polar than ether, very volatile and will evaporate off quickly, THF is a fair bit more polar than ether, and not too bad at mixing with H2O, freely miscible in fact, whereas diethyl ether, whilst still retaining some significant polarity (polar solvents such as lower alcohols, acetonitrile, DMF, ethyl acetate, etc tend to dissolve other polar substances, or be miscible with same, E.g isopropyl alcohol is freely miscible with water) Non-polar solvents, for example chloroform (very slightly polar IIRC, but behaves as a very nonpolar solvent), methylene chloride/dichloromethane, the alkanes like pentane, hexane, and the aromatic ring-based solvents, such as tolene, xylene, benzene (very nasty stuff, benzene is a fairly potent carcinogen which likes to worm its way into DNA and go about its merry leukaemia-spawning way), these are all nonpolar solvents, which like to dissolve things with a greasy, oily, or waxy sort of nature.
Salts of amines (of which methoxetamine HCl is one, assuming it is the hydrochloride and not some other salt, but the end result is the same) are usually soluable, on the whole, in polar solvents, although it depends on other functional groups present and general polarity, amongst other factors, IPA, acetone, methyl ethyl ketone, ethyl acetate and others dissolve many salts, not sure about the specific soluability of MXE HCl, looking for data on both PCP (more data likely available given the wide distribution and use history of PCP) or eticyclidine, of which MXE is a derivative of and the soluability of those compounds should give a good idea of what will dissolve MXE well.
I am pretty confident that methoxetamine base, will dissolve in either diethyl ether or THF. Bear in mind, when picking something to measure THF out, or store it in, that it eats a great many plastics. It is a great solvent for plastics, rubbers and other polymers. Used for welding PVC together for instance. Any plastic that is intended to come into contact with THF, test it first to make sure it isn't going to dissolve and add a solution of plastic to MXE..that would be most unhealthy to smoke, and not to mention, quite possibly so harsh, irritant and foul as to be unsmokable.
Glass would be the best option, glass eyedropper pipettes are easy to obtain, measuring beakers that are designed for small quantities of substance are dirt cheap, as are glass vials. Weigh out MXE salt, add to polar solvent, dry IPA should be decent, but I am not sure....small quantities of MXE will suffice for testing., treat with equal molar weight of sodium carbonate to MXE salt (rather, since the salt form is not actually known for sure to me at least, molar weight of methoxetamine, should be up on wikipedia, or easy, if one reads up a little very basic science, to look up how to figure out molar mass of a substance) Using hot IPA, or warming the glass container in hot water should speed the freebasing up some. I would then do one of two things:
Filter off the carbonate, I am really tired right now, but I am pretty sure that it isn't too soluable in IPA. I only have methanol here, so can't test for sure with IPA, using a coffee filter, wash the area the solution passed through the filter with a little more IPA, to obtain any MXE left soaked into the filter paper, this should, if the soluability of MXE base is decent in IPA, leave one with a solution of it in dry IPA.
On the other hand, if it is poor, one may either see MXE base precipitating out of solution, either sinking to the bottom or floating on the surface, probably looks a little waxy, or oily perhaps, depends on if its a liquid or solid. Never handled PCP at all (not for want of looking mind you, there just is not very much, as far as I am aware here in the UK, compared to the US), so I am not sure off the top of my head. If it does this, before filtering, it may help forcing as much as possible to precipitate out, by sticking it in the freezer, as solubility of most things, gases excluded, in solvents decreases as the temperature drops.
This could perhaps be evaporated (the isopropanol that is), to leave a mixture of methoxetamine base and if it is the hydrochloride salt originally, then if sodium carbonate or bicarb is used, then the residue will be common salt. then I would try dissolving this residue in a minimum of chilled ether or THF, and filtering. Evaporating the solvent in air (working with maybe 200mg of MXE to start with I would try, 100 if a bit more confident in technique), shouldn't take much solvents up, working on the scale of I would say at the most, 20ml.
With 200mg methoxetamine base, added to 20ml of ether or THF, the result would be 10mg/ml, allowing for easy control of dosing when applied with a dropper, evenly over a fag, allowing to dry then of course, smoking.
DO NOT FUCKING SMOKE NEAR ETHER OR TETRAHYDRO-FUCKING-FLAMMABLE-FURAN!
Also do some googling, and read up on the properties of the chosen solvent, both diethyl ether and tetrahydrofuran react, slowly, with atmospheric oxygen, and form organic peroxides, and hydroperoxides. An inhibitor is often added to commercially supplied ethers, to prevent this, and old ethers must be tested for peroxide, which, once one reads up, is not difficult to do in practise. The inhibitors slow down peroxide formation. These organoperoxides are EXTREMELY shock, friction, electrostatic discharge or passing wind too loudly within about 200 miles. Open an old, crusty bottle of ether/THF, thats got a bunch of white stuff in the screw thread of the bottle? the result would not be pretty. Such etherial refuse is sometimes disposed of by calling the bomb squad up to have them safely blow it up.
My own THF is inhibitor free, so must be handled carefully and with respect, for the sake of safety. If a bottle is newly opened, I squeeze most of the air out, then vent a little argon gas from a welding cylinder (small ones are available that have a small screw-on regulator for small welding setups, rather than having to rent a bloody huge tank), to exclude oxygen as much as possible.
I think I shall definately have to experiment on MXE, and freebase some, and do what you US dustheads do, and make...whaddya call the things, dips? dippers? or something like that. No harm in trying it once, worst that could happen is losing 50mg or so of MXE, one IV shot worth.
