Mephedron Glasgow

ically. Add 500 ml of hexane to the flask, and distill off about Buy Mephedron half of it, using a fractionating column. Both water and methanol form azeotropes with hexane. The approximately 250 mis of solution left in the flask is now cooled in an ice bath to about 5° C. When that temperature is reached, . 1 mole of SOa-acetonitrile complex is added.
If the solution prepared is .
5- molar strength, that requires the addition of 200 ml. This addition should be done with strong magnetic stirring, and slowly enough that the temperature does not climb too much. After the SOa has been added, allow the reaction to come to completion for about 5 minutes, then add 18 grams of diethylamine (26 ml) dissolved in 250 ml of anhydrous ether. A further 5 minutes of reaction time is then allowed with stirring, before pouring the whole reaction mixture into a 2000 ml sep funnel.
Now 1000 ml of water is slowly poured into the sep funnel with swirling. This addition of water generates a lot of heat as the SOs reacts to make sulfuric acid, and then gets diluted.
Over a period of time work up to shaking the sep funnel. The LSD goes into the water layer. Separate it off, and extract four more times with 1000 ml portions of water. The combined water extracts (5000 ml in all) are now saturated with salt, then extracted five times with 1000 ml portions of ethylene dichloride (1,2-dichloro-ethane). Ethylene dichloride is heavier than water, so it forms the lower layer in the sep funnel. Practical LSD Manufacture 54 The ethylene dichloride now contains the LSD. Check the extracted solutions with a blacklight to make sure they have been completely extracted. This solvent is now removed under vacuum (a rotovap makes this much easier, but is not the sort of thing one gets at a garage sale). Warm water can be used to heat the flask during the vacuum evaporation. The residue in the flask is a mixture of LSD and iso-LSD. The isomeric mixture comes from using isomerically-mixed lysergic acid.
The iso-LSD is separated from the LSD using the chromatographic method given in Chapter 4, and the iso-LSD converted to LSD by the method also given in that chapter.
Conversion to the tartarate salt is also done in the same way as described in Chapter 4. Journal Method In this method, the formation of the metal salt of lysergic acid is done exactly as given above. Now to the residue left in the flask after vacuum evaporation of the methanol, add 500 ml of dimethylformamide. Half of the dimethylformamide is now distilled off under a vacuum through a fractionating column to remove traces of water and methanol. Aspirator vacuum is strong enough for this distillation, but beware of the tendency for formamides to bump during vacuum distillations.
The vacuum should be strong enough that the dimethylformamide distills at around 50° C. Now cool the formamide solution, and when it has cooled to 5° C, add 100 ml of 1M SCvformamide complex. Allow 10 minutes of stirr
