Mephedrone synthesis (4-MMC) in NMP solvent. Large scale.

[rafael1985]

You make synthesis 3 cmc?
You know I think this simpliest method is better than this but is my opinion

I have a question from a different point of view. Suppose you have a completely airtight room, where fresh air is forced in on one side and a high-powered fan pulls it out of the centre of the room on the other.

How do you deal with the filtration of the odour in the air? Do you use any purifiers, if so, what kind and with what kind of cartridge, or is it enough to give a high-capacity carbon filter with activated carbon on the exhaust as is used in cannabis cultivation. If such a filter would do the job, which activated carbon is best, CTC or ordinary carbon?

How is the air and odours filtered in the laboratories? Regards

KWasdCan you share your method for 4mmc synthesis? I think carbon filter will do the job for youl.

If you need additional help, write.

William DampierI have a tablet containing ephedrine. Can you tell me the method of extraction and synthesis with potassium carbonate and acetic acid? Of course, I heard that it is possible to synthesize with sodium hypochlorite. Here, the access to other materials is limited.

1.First of all, can you please list all of the laboratory equiptment needed for this? I saw that you used a reactor in the synthesis. Is this link below what you mean?



2. And also is a Nutsche filter required. If so, can you please give me a reliable place where I can aquire one. Is there any more equiptment apart from the ones I have listed. If so please tell me what they are and the places where I can aquire them.

3.And in one of your comments in your post, you said you can use this to produce a ton a month. I would like to know how much would 1 production take and how much finished product will come out of the first production.

4. So if you can, please give me a list of all the laboratory equiptment, places where I can buy them. I have a lot of respect for you because of the inforamtion you have posted on this forum which has helped us with our past small-scale synthesis. All because of you and other people on this forum, there has been a BOOM in our client base recently.

Hopefully you can help me sir, and everything will go well.

Best regards,

Aaron Stevens

aaronstevensAs @Level1 said, you need 100l batch reactor with heating system, Nutsche filter, vacuum pump. You can figure out information about items in stock here.

 

[aaronstevens]

thank you for your answer and help, I have another question, is the reactor, the nutsche filter and the vacuum pump, one machine? or can it be a whole set in one machine?

Is the reactor a reactor and the rest are other elements?
Can a nutsche filter be integrated in the reactor?

From what I read and looked, nutsche filter is in vacuum pump, right?
But my point is, is it possible to buy everything in one machine?

Friend, give me answers to the following questions from yesterday:
5. Synthesis questions, points 8 and 9
a.) How much hydrochloric acid to add?
b.) Add hydrochloric acid slowly or quickly?
c.) How long to freeze for and what freeze temperature should be set?

 

[aaronstevens]

Are the images I have attached the appropriate equiptment for the synthesis?

Will this nutsche filter work?

Glass nutsche filters - LPP Group

Buchi nutsche filters can easily be combined with Buchi reactors for solid / liquid separation after the synthesis allowing safe processing of a wide range of solvents and acids.

I honestly have no idea, I haven't checked it. In the next few days I will try to approach this synthesis again I will check it and let you know.

In my opinion, it is the fault of acidification with concentrated undiluted HCL by which the product burns and impurities are formed. Now I will want to add ice-cold acetone at step 8, and acidify successively with a 1:5 HCL:Acetone mixture. It seems to me that this will solve the problem.

The organic phase takes on a nice orange-amber color so I would argue that it is running at least correctly.

KWasd
did you find out why it was blue? , i followed the sythesis with 25g of bk4 and after adding 1:1 hcl acetone to the RM at one point it kinda solidefiend for a sec , then redissolved , then turned blue and bluish poweder praticipated ,

the blue color is methylamine residue i think , i did the reaction and all went well until acidification also , then powder participated and after x<ph 7 it turned blue , but i was able to wash the powder with acetone and it became white

maybe you didnt add enough water to dissolve the methylamine and NMP into it ? i extracted with toluene, idk sometimes it looks like in their videos it works too perfect lol , but i anded up with 12.5g from 25g bk4 , not bad at all for first try

 

[Bennychairman]

if you get blue product it means there is too much methylamine in your organic layer , wash it with salt water 5 times and acidification should go better

 

[fuckypu]

12.5g powder ??
Crystal you get 10g

KWasdHi, can you share your synthesis with 4MMC and if your blue colour problem has been solved? Was it due to concentrated HCL you used?

 

[Chenzen]

Hi guys, I did it like this, why my powder has no power is very weak I use of this on myself 200mg 500mg and I did the zero effect the same as everyone in the movie ?? : (I wash the powder 3 times with acetone. W get blue meph too and noe is white but no effect high

ChenzenHave you controlled temperature during reaction well?

Hi, can you share your synthesis with 4MMC and if your blue colour problem has been solved? Was it due to concentrated HCL you used?

Same question for you. Was temperature of reaction is higher than 55 deg C?

 

[Bartholomeus]

benzene is carcinogenic record video of 4mmc production using nmp benzene is fun and inefficient 40% of the final product very little per 100g bk4 you need to use a 2l flask I use a 2l glass bottle and it yields 300g and 350g of the final crystal product. If you are using benzene toulen dcm xylene nmp you must use different cooking temperatures and the time is different. I do not use a flask, but an ordinary wine bottle, a bucket, a conical separator for wine, cloth for filtration and a centrifuge for drying clothes.

Can you please write your method?
for 1kg 2-Bromo-4 Metylopropiofenon?
Or write proportions you use, you can also write in PM if you don't want to share public
