My mephedrone burns my nose as fuck

[ymaaah]

I made rock 4-MMC and I waited 1 day to let my solution dry and crystalize 4-MMC, I decided to test it and when I sniffed 70mg, my nose fucking burned, especially my skin, I think acetone is still in my product..what can I do to dry my mephedrone from acetone?

 

[HIGGS BOSSON]

Acetone evaporates quickly. You need to dry your crystals well in a dry, warm place.

 

[ymaaah]

Yeah this is why I had a doubt.. but its weird

from what you are commenting and I can intuit and deduce that it is not about the acetone, rather it will be that your bromo-ketone has not finished reacting well and traces of bromine remain in the product, be very careful and if you notice itching afterwards from recrystallization please be safe without consuming the cat

What method You this crystal and jest time You wait for result

 

[ymaaah]

I take 1g 4MMC for 1ml of water, I put water in a pan, I heat it until the water starts to boil, I add 4MMC and after it was like oil, I putted it in a glass, I putted the glass in my attic (its very cold ahah) and I wait 1 day, it was solid rock, but I think I didnt filtrate my 4MMC powder enough before, because I saw impurities in the pan when I boiled the water

To the Next time,add more methylamine in your synthesis is very possible with your cook-method the methylamine does not displace bromine from the product well,and the result is that itch that burns in your body.

 

[ymaaah]

for 10g of 2B4M, I put 20ml of methylamine 40% but I just remember that my seller told me that the methylamine wasnt not 40% but a little less because he made it for me (if you read this, thank you again !), so maybe I have to put 25ml, no I only have burns in my eyes (even when I wear glasses, like ski glasses but for chemistry and a mask too (ABEK1) but its not 2 in 1 its 2 products different, I cry a lot the next day ahah, but 2 days after they are normal) ant thats all, I wear gloves and a 3M suit

The place I make 4MMC is my attic and I let the window open the night so its cold.. Maybe the reaction is not hot enough ..? I have a heating plate so I can make a hot water bath and put my bottle containing 2B4M/M40/DCM inside to start the reaction but I cant see the temperature, so...

Oh and I have another question, when I put HCl and acetone in my 4MMC freebase I can stir some minutes and filtrate or I have to put it in a freezer? Because when I put acetone, I see 4MMC rocks and it is very very white so maybe I can do it?

ok friend... well, then it is with total certainty that the methylamine has not done the job well and has not succeeded in displacing the bromine, which is what produces that tear effect... The methylamine that you are using is not in the proportion correct so you should add an excess of it..ok?, next batch add 30ml or 35ml of methylamine this will not ruin your work at all, on the contrary, an excess of methylamine generally favors the synthesis of bromoketones made in home laboratories since the controlled environment for the synthesis is not available. try to make another batch and at room temperature give it more time to react well, I cleaned its base well at least 3 times with distilled water, and yes, when you add the cold hcl drop by drop at 1:5 with ice-cold acetone, put your magnetic stirrer at full speed, because when the hcl is added on the base, this must be in constant movement to produce the salt (this can take a little time for the mephedrone crystals to begin to appear), once the pH reaches 5 its glass The precipitate must be full of crystals, let it move for another long time and then put it in the freezer for a few hours. Once this is finished, filter the crystals and dry them well to proceed with their recrystallization in acetone and water.

I dont have magnetic stirrer, I make 4MMC with a small vodka bottle so.. but I can buy it or maybe do you know a DIY to stir quickly a solution for this time? I can mix slowly the solution in a glass while some minutes I think, no? And maybe this is why my yield wasnt good !!

 

[Acidosis]

The best option would be for you to invest a few euros or dollars, depending on your location, in a magnetic stirrer, even if it is one of the cheap ones that does not heat, it will only shake its base, but I am sure that you will use it a lot and once you buy it, you can also use it. to do all the work from start to finish. But for now, what you should do is place its base in a beaker and stir constantly with a rod while you add the hcl, always remember to keep everything frozen while you form the crystals, you can use a bucket full of crushed ice and put your glass inside between the ice with the base and add the hcl slowly

 

[ymaaah]

Okay I will do that, idk if I buy vevor stuff or not, I think I will, because its cheap !

In your previous thread, I wrote to you that you have about 1.5 grams of methylamine hydrochloride impurity. Learn to read carefully - it will solve many problems.

Ps. It was a week ago, I foresaw this problem)
