Meow Meow "Voss" synthesis

Legend!

Now, where do I get HBr in required quantities and concentration in the EU as a casual consumer? Is making it at home the only way? Similarly, how do I get or I purify hydrogen peroxide to 35 % when all I can get is max 10 %?

 

[Dr. MMX]

you can buy it on allegro, they dont check anythinfg they just send 35 %

 

[dnBQByvHb8Zkawbjpx]

I checked very briefly. Two sellers of 35 %, both require a filled declaration on explosives precursors and will only sell to businesses, or so they say.

 

[Dr. MMX]

just buy and you will see

 

[dnBQByvHb8Zkawbjpx]

I prefer not to poke this bear. According to the EU regulation sellers are to report suspicious purchases, including attempted ones. I don't need to end up on any more lists.

 

[abis777]

Is only 12%

crystallization of 2b4m, add dcm or ethyl acetate to the 2b4m powder, heat the whole thing until all the 2b4m dissolves and put it in the freezer overnight and a clean 2b4m glass is created, but it works best in dcm proportions 1g 2b4m powder per 0.8ml dcm saturated solution similar to mmc crystallization

 

[Dr. MMX]

you cant use dcm for crystalisation.. i mean you can but you must wash it with acetone later. Why use dcm at all?
Water and if product isnt pure, then add some ipa alcohol to help crystals grow.

 

[WillD]

Not sure that 10% will work. We need to try it. I think this is possible, but will take more time. And more frequent shaking and possibly additional heating. But I think this is possible. We can replace HBr, but it will be a different method.

 

[WillD]

If you can buy BK, then part of the problem is solved. If not, then you can use other methods of bromination or iodination.

 

[animeboro]

I would do it like this we get 4methylenopropiophenone per 100ml 150g 2b4m used 750ml ethyl acetate methylamine hcl 195g/naoh 105g+distilled water 150ml rinse 3 times with distilled water, 450 ml each (total 1.4 l) and hbr acid to pH 5 if the powder is brown, use water and NACI salt, heat the whole thing and put it in the freezer at -18°, then the whole NaCI will remove the dirt crystallization mmc powder + tap water or tap water and ipa 1g mmc to 0.8ml of water heat the saturated solution slightly, set aside at room temperature and the next day we have a crystal or use 1g of powder 0.8ml tap water and 0.2ml ipa and do the same as with just water

 

[Dr. MMX]

I think it can be failure of NAOH and methylamine without stirring (very effective) but you can try

 

[animeboro]

your method works, but the proportions of naoh and methylamine are smaller because then the entire 2b4m reacts with methylamine, you use too much methylamine and naoh and, as you said, a green freebase is created, I received it yesterday and it turned yellow immediately after 30 minutes but I leave it for 1.5 hours so that all the methylamine reacts well and, as I said, the reaction ends when the bottle starts to cool itself.

 

[WillD]

As you see in the photo, there is no brown powder. pH is approximately 4-5. I repeat - it is better not to use hydroxide in synthesis with ethylacetate, this reduces the yield. The best to use triethylamine and make a methylamine solution in EtOH or IPA.

 

[WillD]

If you use 40% methylamine, the mixture is heated very much, and the reaction ends quickly. It makes no sense to keep more time, on the contrary, it is advisable to cool the mixture if it does not begin to cool. If you have methylamine in a lesser concentration, it may make sense to change the time for the reaction.

 

[animeboro]

Maybe next time u show as this way what you say now

 

[Dr. MMX]

remember that if you use na oh and ma hcl yoiu get methylene chloride, whilew e basicly need methylamine.. its very controversial but as I said its used while you cant have the MA aq or you cant buy the good quality. I informed that green color occurs very fast and its the sign that its very good reaction and soon its finished, but to be safe its better to spend 30 mins or 20 i refered i dont remember, when green color occurs. You cant really extend this reaction, its the purity that you fight for. I received almost pure product, with very good yield.

Genius play for ethylacetate making it pro solvent for this is using IPA with methylamine like Expert suggest

 

[WillD]

Yes, this can solve part of the problems that everything is found with the synthesis in ethyl acetate.

 

[animeboro]

It would be nice to show the yield of this synthesis on a scale so that everyone would not have to ask whether the synthesis is good or not, just because it is produced does not mean that it is the best.

 

[animeboro]

brown mmc powder is created when we add the acid too quickly and the freebase starts to overheat, then all the pyrizine and other impurities start to come out, which means that we have lower efficiency. the same way we clean the wrong MMC free base, I use water and water with baking soda 3 times and water with baking soda always saves my life even when the entire solution did not react after rinsing with water and baking soda, I get the free base from the green oil of the MMC free base to yellow, changing the color green to blue and then to yellow

 

[WillD]

We can all rush, especially when the product is needed now But we can speed up the process of acidification with compulsory cooling, for example in a pan with cold water.

 

[animeboro]

Is better way dry ice they for shure u temp no up and the same time u get powder if use hcl i dont use hbr then i can say is better or no

 

[WillD]

I heard about this. Perhaps mineral components in tap water are given crystallization centers.

 

[Dr. MMX]

I believe it does help to form them. But I dont agree that tap water will be better than distilled. Simnply the temperature must be very carefully dropped down to form 1st crystals (even sometimes it can be incrashed a bit to decrashe it again to receive nice nick in to 1st crystals that will appear, it will modify its shape.). Crystalisation can be finished in less than 2h receiving such result with about 60-65% powder's weight from mother liquior, then repeated and the about last remaining 5% should be left to be just drippefd with acetone lightly. of course its estimated grams. But I believe 60-65% for mother liquior is very good score (till 25c)

 

[Dr. MMX]

if the solution did not react, adding the water doesnt change anything.
Here its only methylamine that is washed as its auqenous layer.

 

[dnBQByvHb8Zkawbjpx]

When you talk about overheating, what temperature are you actually talking about? The last time I did acidification I had a thermometer in the RM and it finished just above 0 °C.

 

[animeboro]

these are my 2 favorite methods with ethyl acetate and dcm+nmp. ethyl acetate solvent price availability. dcm+nmp performance and speed of execution in 35min+/-
