Рекристализираният продукт е по-чист и следователно по-силен. Освен това се получават големи красиви кристали, които са изключително привлекателни за потребителите.

минусовата температура не е задължително условие. можете да направите същото и при температура + 20С. но колкото по-висока е температурата в помещението, толкова повече 4-mmc ще остане в майчината течност. при -8С почти всички 4-mmc ще изпаднат от разтвора. при + 20С около 70% ще изпаднат, около 30% ще останат във водата. но какво ви пречи да изгоните водата и да получите остатъците от 4-mmc, а след това да повторите процеса на кристализация отново?

Водка 40% чистота и Витамин С чистота и u имате максимално чист кристал по-късно измийте с ацетон и това всичко

To begin, after oxidizing the solution, you'll need:

If you're oxidizing with water-based hydrochloric acid:
When the pH reaches 6.5-5, you need to remove the solvent layer (if it's DCM, it's on the bottom)
(if it's ethyl acetate, it's on the top)
If the sediment is thick, simply add distilled or iodenized water to dissolve all the mephedrone (since if you end up with a mush, the acid can burn the precipitated mephedrone).
So: leave the water-based mephedrone, you can add DCM, mix it until the color is lighter (1-2 times is enough), then discard the DCM layer, then add isopropyl alcohol (IPA) at a rate of 15-20% of the total solution. NEVER ADD ACETONE; the yield will be lower. IPA also removes iso-Mephedrone well. Place it in the freezer. For a faster reaction, you can add flour to the remaining solution and stir it, thereby accelerating the precipitation of mephedrone hydrochloride.

The next day, when your solution has solidified, you can filter it through a Büchner funnel. But before doing so, you can mix your wet flour with ice-cold acetone in a container.

NEVER POUR ACETONE INTO A Büchner Funnel WITH FLOUR!

Since the acetone doesn't have time to rinse the flour, it passes more slowly in the dirtiest areas, thereby taking the flour with it (it's better not to evaporate it).
Next, filter the mixture without using a funnel. If the dirt hasn't come off, there's no need to rinse it again with acetone... it's already washed everything it needs to. Try a different solvent, like ice-cold IPA.

Before preparing the solution, when dissolving the dry flour in water, you can rinse the solution again with DCM.

After this, dry the flour and, of course, crystallize it in the solution, depending on your needs and the time you have for crystal growth.

If you use IPA oxidation, your flour should be almost pure and white—unless, of course, you burn it, but it's more hassle. I don't recommend this oxidation method.

If you want beautiful, large crystals, your flour should be snow-white, and your vessel should also be sterile.

I cover this in more detail in my articles.
If you have any questions, please don't hesitate to contact me.

Для начала вам потребуется, после того как окислили раствор:

Если вы кислите соляной кислотой на водной основе:
При достижения ph 6.5-5. Вам нужно избавиться он слоя растворителя (если это DCM он снизу)
(если это этилацетат он сверху)
Если осадок густой просто добавьте дистиллированной воды или йоденизированной, что бы весь меф растворился (так как если у вас будет каша, вы можете кислотой сжечь ваш выпавший меф)
И так: оставили водную основу мефедрона, можете добавить DCM смешать что бы цвет был светлее 1-2 раз достаточно, далее слой DCM в утиль, следом добавили (IPA) изопропиловый спирт 15-20% от всего раствора. НИКОГДА НЕ ЛЕЙТЕ АЦЕТОН, выход будет меньше. Так же IPA хорошо вымывает изо-Меф.
И ставьте в морозилку, для более быстрой реакции вы можете добавить муку в оставивший раствор и помешать его, тем самым ускорив процесс выпадения гидрохлорида мефедрона


На следующий день, когда у вас раствор застыл, вы можете его фильтровать через воронку бюхнера. Но перед этим можете смешать вашу влажную муку с ледяным Ацетоном в таре.

НИКОГДА НЕ ЛЕЙТЕ АЦЕТОН В ВОРОНКУ БЮХНЕРА С МУКОЙ!
Так как Ацетон не успевает промыть муку и в самых грязных месстах он проходит медленнее тем самым забирая с собой муку, (лучше чтоб не выпаривать)
Далее прогоняем не через воронку. Если грязь не смылась, не нудно промывать опять ацетоном…все что нужно он уже промыл, попробуйте другой растворитель туже (IPA) ледяной/

Перед заготовкой раствора, когда растворяете в воде сухую муку, вы можете еще раз промыть раствор с DCM.

после этого сушим муку, и естественно кристаллизуем по раствору зависимости от ваших запросов, ну и времени которое у вас есть для роста кристаллов.



Если вы используете окисление на (ipa) то мука у вас должна быть почти чистая и белая, конечно же если вы ее не сожгли, но мороки с ним больше. Данный способ окисления я не советую.

Если вы хотите, красивые и большие кристаллы, ваша мука должна быть белоснежная, так же должна быть стерильная посуда.

Более подробно, я рассказываю об этом в своих статьях.
Если будут вопросы обязательно обращайтесь.

For future reference, don't rinse the aqueous solution with anything other than DCM or DHM. Ethyl acetate might absorb some of the residue, but that's okay. The yield will be 15-20% higher since Hbr is heavier. However, you should be aware that the effect is slightly different.

What is the best way to make crystals from 4 mmc powder?In proportions 1:3 powder/water or.watwr/ipa is like snow or sugar in temp 22 degrees after few hours

1 : 1,5 : 0,5 4MMC: water: acetone
Heat the water to 40 degrees, dissolve the flour in it and add acetone at room temperature.

Everything must dissolve, absolutely everything.

Heat in one dish, crystallize in another. The dishes should be clean. And put the dishes on a towel, cover with foil or food film. make small holes

On acetone, the product is more stimulating.

The temperature should be cool. The growth of crystals takes about 4-5 days

1 : 1,5 : 0,5
4MMC: Water: IPA (isopropyl alcohol)
Everything is exactly the same as in the recording with acetone.

We need large crystals, we wait longer at room temperature

At a temperature of +17~+18 'C, the crystals are smaller and more beautiful

On the IPA effect with more euphoria.

The choice is yours

The effect may also be different if you acidified Hbr

Apparently, it's time to record a review of crystallization on all solvents, at different temperatures... and under different conditions, so that there would be no more questions

I synthesized 4-MMC using ethyl acetate.
I didn't have acetone during crystallization.
Can you tell me how I can obtain clean 4-MMC crystals without any acetone?
Could you tell me in detail?
Thank you, teacher.
Thank you, my teacher.

Try this option, there is a photo above in the post.

If it's hard enough for you to understand. You can write to me in private messages.

We can do it together step by step. You'll make it! I believe in you!
