REDSHIELD5'S “QUAD SOLVENT RECRYSTALLIZATION” TECHNIQUE by “JoeyCanofAcetone” Due to a high volume of requests for information regarding the purification of street meth and my never ending quest to, at least partially, isolate methamphetamine hydrochloride from a crystallization matrix of illicitly manufactured “dope”, I have decided to produce a more in-depth technical writeup of a procedure I “invented”, practiced and refined over the course of the last few years. The following information will result in a rather vigorous cleaning of street meth and will remove most impurities and undesired chemical compounds except for a select few advanced cutting agents, commonly believed to be various structural isomers of methamphetamine such as n- isopropylbenzylamine. There is actually some uncertainty about whether or not this procedure may reduce the percentage of n-isopropylbenzylamine present in the starting material by weight. This uncertainty stems from the similarity in this procedure to a writeup which was composed by Reddit user /r/spare_me_thy_bs which claims to be able to successfully separate the desired amine from the aforementioned cutting agent. Materials You Will Need: Street meth Numerous flat pyrex baking dishes Various small glass jars Unbleached coffee filters (optional) Glass pipette or syringe containing no plastic or otherwise potentially contaminating material 1 glass scooping apparatus (to cleanly move the material between dishes) 1 wooden pencil or similarly sized item 1 hotplate/heatgun OR unused/clean hair straightener (with temperature adjustment) Anhydrous or ACS grade Acetone Anhydrous Isopropyl Alcohol Anhydrous Ethyl Alcohol Distilled Water 1 Jewelry scale (optional) 1 DIY “roof” which can sit a couple inches above the Pyrex dishes to cover them during evaporation. Procedure Street methamphetamine of varying weight was crushed to a fine powder inside a flat Pyrex baking dish until the smallest possible particle size was achieved. This powder was then pushed tightly into a compact pile in one corner of the Pyrex baking dish, and any residual material was meticulously collected and added to this pile. The side of the baking dish containing the starting material was elevated slightly by placing a wooden pencil directly underneath it, so that the dish rested at a shallow angle, with the starting material elevated. In a small glass jar, anhydrous isopropyl alcohol was brought to a boil (180.5 ° F/82.5 ° C) using an electric heat source with an unbleached coffee filter placed loosely over the top of the jar to avoid dust or solid material from getting into the jar. Once this solvent reached a rolling boil, a syringe or pipette was used to draw it from the jar. With an unbleached coffee filter over the starting powder, this boiling solvent was dripped liberally onto the pile and added until the pile became visibly, but not overly wet, and enough isopropanol was added so that the solvent could begin “running” down the length of the dish, and away from the pile of starting material. Note : Methamphetamine Hydrochloride is only very slightly soluble in cold or room temperature isopropyl alcohol, but significantly more soluble in warm, hot or boiling isopropyl alcohol. As the isopropyl alcohol cools, running slowly down the length of the pyrex dish, the methamphetamine becomes less soluble as it travels, crashing out of solution as the alcohol travels, while other impurities stay trapped in the liquid solvent volume, and mechanically separate themselves from the original material with the aid of gravity. This movement of the isopropyl alcohol was allowed to proceed slowly, but not too slowly, as this would result in a longer period of time in which the methamphetamine and the other soluble material remained together. Once the alcohol reached the bottom of the Pyrex baking dish, a glass scooping apparatus was utilized to collect the material which remained closest to the original pile, and this material was added to a new glass dish, which was loosely covered and allowed to evaporate and dry completely. Once dried, this material was then, again, crushed into a fine powder of the smallest reasonable particle size, and pushed tightly into a compact pile in one corner of the second dish. Anhydrous or ACS grade Acetone was then dripped through an unbleached coffee filter onto this material, and the side of the dish containing this material was rapidly – but carefully – elevated to allow the acetone to run away from the pile. Note: Methamphetamine Hydrochloride is insoluble in anhydrous acetone, and the acetone in the dish will contain any impurities which may be soluble. This “gravitational” separation of the material and the solvent volume is notably cleaner than performing an acetone wash by adding the material directly to a coffee filter, and can be used to effectively avoid any filter losses which may occur by doing so. A glass scooping apparatus was used to collect the insoluble material, and it was added to a new Pyrex baking dish. In a separate, small, glass jar, anhydrous ethyl alcohol was brought to a boil (173.1 ° F/78.37 ° C) using an electric heat source. The alcohol was drawn up with a glass pipette, and dripped in small quantity through an unbleached coffee filter onto the material until the material became dissolute, and the dish was loosely covered to avoid contamination from airborne particles during its evaporation. Upon evaporation, the material was again collected, and placed into the smallest possible glass jar. An unbleached coffee filter was placed over the opening of this jar, and a very minimal quantity of warm distilled water was dripped into this jar until the material became once again dissolute. A dry unbleached coffee filter was placed – inverted – over the top of this jar and the material was left to evaporate under bright lighting or sunlight. The precipitated crystals were collected, weighed and sealed in a closed glass jar. Yields were analyzed by weight and material from each of the successive baking dishes was collected for analysis. -JoeyCanofAcetone
