And I dont understand why I have so much 4MMC whereas I used just 20g of 2b4m https://ibb.co/Dbrvm0Z
maybe its because I let the freebase in a bottle while 5 hours?

4MMC freebase with HCl/acetone didnt react

Normally, the addition of the acid is done with the aqueous layer, for several reasons.
The first reason, do not lose the product, it goes all into the water layer. acetone and acid give impurities, acetone dissolves mephedrone quite well, and even more so in the presence of water from acid.
The second reason, if your ph has gone even to 1, when the water is evaporated, all the acid will fly away with the water vapor.
The color of the product, as you remember, is often due to the admixture of 4-methylpropiophenon in bk4 (2b4m). It was noticed that when the ph goes below 6, impurities begin to fall out
And wash the solvent from methylamine qualitatively, then there will be no excess weight and will not burn the nose.

The aqueous layer, you mean the top layer with methylamine/water??
idk why, my pH goes from 6-7 to 1-2 with a few drops.. I bought a pH metter, so I will check precisely pH !
I washed with acetone and my powder is like that : https://ibb.co/Yhk2LKT Yeah its white but I can see some small green reliefs
But I think I will recrystalize with IPA

you only need water before HCl to dissolve the powder, so you will take the maximum (if you additionally wash the dсm layer with a small portion of water). Next, you need to carefully evaporate the water (you can in a vacuum or a sand bath, for example, the main thing is not to overheat above 110 degrees). Usually I wash the aqueous layer with an organic solvent for cleaning, then I partially evaporate the aqueous layer and put it on crystallization (I previously posted photos of crystals 20 mm in diameter, they are made using similar technology)

Here is a photo https://ibb.co/ZWcfSyy
This powder is obtained from mother liquor waste after multiple crystallizations. decided not to throw away the residual orange liquid, cleaned it up and got a powder. The left photo is the beginning of crystallization in solution.

So if I understand after the methylation, you have 2 layers, at the top you have methylamine/water and at the bottom you have 4MMC freebase, you acidifiate before remove the top layer or after? (sorry im french not english, even with google translate I have some difficulties to understand the meaning..) And after, you wash your 4MMC freebase with vacuum or sand bath. I have MgSO4 to remove all the water but I dont really know how to use it, put MgSO4 in the 4MMC freebase, put small amount of water, mix and remove all water?
I am soooo bad sorry

1. Abattre (jeter) une couche d'eau avec de la méthylamine
2. Rincez abondamment la couche dcm avec de l'eau (je fais un volume égal, c'est-à-dire que si nous avons 1 litre de dcm, je rince 4-5 fois avec un litre d'eau, pour un total de 4-5 litres d'eau)
3. J'ajoute de l'eau à la couche lavée de dcm (pour chaque gramme de bk4 d'origine, je prends 4 ml d'eau)
4. Ajouter lentement l'acide chlorhydrique, en mélangeant soigneusement par portions, entre les additions d'acide, en remuant pendant encore 3 à 5 minutes. J'ajoute de l'acide à ph 6, les dernières portions d'acide sont beaucoup plus petites que les premières portions.
5. Je sépare la couche d'eau (laissez-la), lavez la couche de dcm avec de l'eau propre (sur la base de 1 gramme de bk4 initial 0,5 ml d'eau) et mélangez soigneusement, vous pouvez la laver deux fois.
6. Nous connectons les couches d'eau (eau des étapes 3 à 5) et nous nous évaporons à une température ne dépassant pas 110 degrés. Après évaporation, le mélange lui-même cristallise, refroidit et triture avec de l'acétone.

U throw acid HCl and later water 2 or 3x and water u heat and u get mmc water get out powder u get Simple.
But on big scale to much work

A sand bath is a metal container with sand, the heater is an ordinary electric stove.
Evaporate the water in which mephedrone is with acid, get a powder, wash it with acetone until white (acetone washes should also eventually become colorless). Acetone washes in the freezer, some of the flour will fall out of them (yes, this is a dirtier product).
Crystals can be obtained from vodka, this is the easiest way.
When you add an acid to a free base, the free base forms a salt (there is no oil free base).

alcohol strongly dissolves mephedrone. suitable only for growing crystals with the condition that we get back the remains of the powder from the mother liquor.
Ethyl acetate washes bad impurities in mephedrone, in addition, it is very chemically active and usually contains acetic acid.
only dry acetone removes impurities or dichloromethane / dichloroethane well (after these, you still need to rinse with acetone, organochlorine poison)

only underwear needed for filtering. down shifter and be proud of it)))
but seriously, the lab standards were invented by idiots, if listen you. EtOAc lol
Ethyl acetate is subject to hydrolysis into alcohol and acid, and you also give it an alkaline)))

If mmc is legal u can play with lab equipment.
But if u want made 500kg per day u have reactor glass 1000l
Only 100l and is expensive.in Poland use plastic reactor 1000l and mix throw acetone acid and finish illigal lab dont Play with nice lab made fast sell fast and buy.

500 kg its reactor 8000l need, if per one work up.
Who use 1000l glass))) Steel or PTFE coated only. Some people use polyethylene, but plasticizers will get into the powder.
Good equipment and the right production cycle speeds up the process and improves quality.
It’s not for you to teach me, your scale is far from 500 kg at a time or per day, you cook a couple of kg and try to justify your shit cooking, it’s much easier not to try to be proud of shit and even more so not to publish it. Now you are trying to cover yourself up for some reason, this is ridiculous)))

did you have to reheat the free base or did you just throw in cold acetone? Or do I just mix the cold acetone with the freebase at room temperature?
