MMXBut crystallization takes too long, needed finished product sooner so the rest batches I rapid crystallized. Maybe when BK4 arrives I do couple batches like this

 

[MMX]

To start with it's all good but I don't think you're gonna spend several days cooking 100g bk4 batches. The experts probably gonna tell you more because I just started and got only few weeks experience. Bear in mind there will be a lot of smell and even your clothes will smell of mephedrone

Berlin777did you do anything to get out fumes or something or you were doing that in place when you dont need to care? i ll do it in place when i must care about smells. Not sure if carbon filter will be enough

Berlin7773m 6057 are filters model for my maks, is it suitable for that? its called in description thats to work with gases of 0.1 (1000ppm) in air

MMXI installed carbon filter recently when already the place I cook stinks. I will test ozon generator if this helps getting rid of the smell in place I work. According to what the experts said carbon filter may be not enough

I’ve seen very good thread on this forum about lab set up, they say about wet filtration method.

3m 6057 are filters model for my maks, is it suitable for that? its called in description thats to work with gases of 0.1 (1000ppm) in air

MMXI do have 3M as well but I’m unsure what model, gonna take a look tomorrow but I know it’s great. If you’re buying 3M I recommend also buying spare harness. Mine just snapped recently in the middle of synthesis when I was putting my mask on

Berlin777oh sorry i went out of reply,


I alrteady have 3m mask beacsue earlier i needed it for somethin else, but filters are outdated for such thing ,i found that 6099 is the best, there is even MA described, clorides etc. I dont have full maks but i have gloves for eyes with protective gum


can you link that wet filtration, i mean i typed into search but cant see a topic

Berlin777there is no info about that machine
but im already looking for that

MMXmaybe ozone generator will help, let me know if you apply that . I cant really get into odor a place i will be in, but giving odors out of place is prohibited as well, but i only have carbon filters and have no idea what else it may be maybe HEPA + carbon

MMXi ve found some details when i typed in googel " laboratory air purifier" there are some deivecs, for less than 1k euros

MMXhepa e12 or e13 tfilter should be cool with a carbon filter and fan intake with a spiroflex into odors direction, i got 3d printer so im gonna build some i guess

MMXI investigated a thing, just look for h13 hepa filter for xiaomi purifier, it already has everything, probablyu it wont last long but should absorb fumes, h13 filter is about that. connect a vent by spiroflex and seal it with a good quality tape, 3m or somethin from castorama or most expensive one or soemthing. Fan should be ok 100-200 m3h and in case its too strong, i mean if outcome of air will be too much filters mayu not filter everything, there is no way to just buy h13 filter they are all for air purifiers and not sure what amount of m3h is correct, so if you buy volt regulator cheapest one you can control fan a bit to find best fit i guess. They use h13 filters in pro laboratory air purifiers, they are just more professional, buit i think most imporeatnt is a intaking air in its source then filtring it

MMXIf you’re looking for carbon filter + exhaust fan you could try in local grow shops then you won’t need to order from internet. I got hyper fan 8” + mountain air carbon filter. It’s all running but the room is already smelly

MMX"ventilation and odor removal:
Scrubbers are used for cleaning gaseous media from impurities in various chemical and technological processes, they are gas purification devices based on gas flushing with liquid.
Scrubbers are designed for capturing gases discharged from the reactor. The cleaning of gases from impurities by means of scrubbers belongs to the wet scrubbing method. This method is based on washing of gas with liquid (water, alkaline solution, and others) at the most developed surface of the liquid contact with aerosol particles and the most intensive mixing of the cleaned gas with liquid. This method allows removal of dust, smoke, mist and aerosol particles (usually unwanted or harmful) of almost any size from the gas.
The following types of scrubbers are distinguished:
- nozzle-type towers (nozzle-type scrubbers);
- sprayed cyclones (centrifugal scrubbers);
- foam apparatus;
- Venturi scrubbers.
The operation of wet gas scrubbers is based on capture of dust particles by the liquid, which carries them away from the apparatuses in the form of sludge. The collection process in wet dust collectors is improved due to the condensation effect - enlargement of dust particles due to condensation of water vapor on them."

Berlin777sadly i didnt find a lot of info on
- nozzle-type towers (nozzle-type scrubbers);
- sprayed cyclones (centrifugal scrubbers);
- foam apparatus;
- Venturi scrubbers.
but will do more research later

i got just 10 kg of carbon filter so i canm do it myself

Berlin777looking shiny! I am still looking for a good lab location nothing near to where you are right now, again good job!

 

[$!$]

After some failures due to my lack of patients finally got some good results thanks to @William Dampier @Marvin "Popcorn" Sutton and passive spectator @G.Patton

My first batches were pretty shit because I rushed too much and didn't use appropriate equipment. For instance I used 250ml drip funnel and I waited only for couple of minutes for the layers separation because I wanted to finish asap and that was the result (1st picture) , I'm gonna blend it, rinse it and crystallize it.
For the first batches I used BK4 and MA40%

After few fuck ups things started getting better, recipe changed a little bit because there are some issues with MA40% but I feet comfortable with current method.

Current method is cold synthesis, works good for me:
500g BK4 is dissolved in 1500ml DCM in 6L flat bottom flask using magnetic stirrer
500g of NaOH is dissolved in 1L H2O cooled (about 10 C) down and added to the flask
750g MA HCl is added to the flask in small batches so the temperature doesn't raise too much, roughly 100g - 150g every 10-15 minutes
The lid is closed and it's left for 16 - 24h hours on the stirrer

After that salt has to be filtered with buchner funnel, then the layers separated prepared for washing.
For first washing I use 3L filtered water with 150g sodium bicarbonate heated up to 30 C
Second washing just 3L of filtered water.

Once it's washed I use about 160ml and 800ml acetone for acidification and to get mephedrone powder, once pH 5 or lower is reached I put it to the freezer and leave overnight.
On the next day I filter as much as possible and leave it to dry. When I skipped that and filtered still wet mephedrone the yield was 240g, yesterday I done it Marvins way and it was 258g.
Marvins way
1. Filter
2. Dry
3. Rinse (cold acetone)
4. Dry
5. crystallize

Crystallization
1:2 powder mephedrone to water and alcohol 50% of the amount of water

I just pour the water to the pyrex glass bowl add mephedrone heat it up until little bubbles appear, boil for 5 minutes, switch the heating off and add alcohol the pour it to the crystallization dish and wait.

So if we compare how it stared and how it's going it's a big difference.

Berlin777Hello boss.
How much gram you get when crystal was dry ??
I'm say crystals no powder

$!$I don't check it anymore to be fair because the last batches of crystals are not pure enough to sell them so I wait for complete evaporation then purify whats left. Now I had about 400g ground and purified crystals from several batches.

 

[Berlin777]

i see u are use methyloamine hcl and u made your self monomethyloamine
with NaOh and water i made like you say up ??

$!$Gas is released in reaction flask after adding MA HCl. I am not sure what's your question.

Berlin777To get 1l methyloamine 40% in water you use
500g NaOh
750 methyloamine hcl
and 1l water ??
