4MMC freebase with HCl/acetone didnt react

[ymaaah]

I made my 4MMC freebase but I had to go to work so I let the freebase in a bottle while 5h, and when I came back to home, I see a yellow oil, but very very yellow, so I took 10ml (for 20g of 2b4m) and I putted drop by drop HCl and I dropped to much and I had a red color when I test the pH so it was 1-2 I think, after I putted 50ml of acetone and the pH was about 4-5 so it was good but there was no white milk, it was still a orange oil, so I decided to put the oil in a pyrex plate and wait tomorrow, this morning I saw crystals on the plate, I will see tonight if there is changement, do you know what happened? Why, even if there was no white milk, the solution made 4MMC crystals?

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?

U need know u are chemist

 

[SonicNL]

What solvent did you use?

 

[w2x3f5]

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.

 

[mocnykutas]

when I see how you make mephedrone, I wouldn't even want it for free. piles of nonsense you write a massacre.
I bought from the same vector ketone and I have a pure white powder and high efficiency. you just don't know how to do it well and that's the synthesis and that's the problem.
It's the basics of chemistry and you're making Egypt's riddles out of it. xD

 

[w2x3f5]

this is what a person who cooks mephedrone in glass jars in the kitchen tells me, uses underwear instead of a filter. I'm not interested in what you think, your level of knowledge demonstrates your kitchen laboratory. )))

 

[ymaaah]

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

 

[w2x3f5]

You need to separate the top layer of water with methylamine after the reaction (if you are using dichloromethane). the dichloromethane layer must be thoroughly rinsed from methylamine (general rule more washes, but with a small amount of water).

When adding acid to dichloromethane, water must be added in advance, the calculation is 5 ml of water per gram of mephedrone. After neutralizing the free base with acid, separate the water (I recommend washing the dichloromethane layer a couple of times with water thoroughly and evaporate this water, there will still be powder in it) and evaporate, so you get the maximum powder yield. Next, wash the powder with ice-cold acetone.

plastic ph meters do not like organic solvents , it is better to use good universal test strips. I like Czechoslovakian, very accurate.

 

[ymaaah]

I dont really understand, so you say me to put water in the 4-mmc freebase and put acid after? my HCl acid is 36-38% so there is water inside..

This is my result the previous time I did 4-mmc : https://ibb.co/4mJFQLj

my pH was not 1-2 but 6-7 (the color of the pH test was green) and after putting HCl until 6-7, I putted acetone and I saw white milk with 4mmc rock, its not the good method? Because I did the same method for this actual synthesis, I just putted HCl to much..

There are so much synthesises idk which is the best

 

[w2x3f5]

Can you call a good method in which you lose a lot of powder due to a mixture of acetone and water?

yes, it’s easier to acidify everything into water, there is not enough water in hydrochloric acid to completely extract powder into water.

 

[w2x3f5]

although do as you know, you probably know better))) less competition in the market)))

 

[w2x3f5]

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)

 

[w2x3f5]

to get an answer, you need to write what you did exactly.
ps. topic about mephedrone, not about 3,4-methylenedioxy methamphetamine
create topic best variant

 

[mocnykutas]

Made mmc dont need lab equipment to made on big scale also if u are Smart u dont need.
On dcm is to much work and need tu much equipment.

 

[velcro]

Do you use NMP?

 

[mocnykutas]

Ethyl acetate

 

[velcro]

Ok, thank you.

 

[w2x3f5]

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)))

 

[mocnykutas]

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.

 

[w2x3f5]

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)))

 

[mocnykutas]

Pure freebase.

 

[ymaaah]

I had this color when I let the solution in a bottle while 5h

 

[w2x3f5]

pure free base colorless liquid lol
