Pyrrolidine is findable in Europe ?
3l of pyrrolidine for 1kg bromo should be ok?
No. 0,9kg (~1L) of pyrrolidine for 1kg alpha-bromovalrophenone.
You mean the porpotion is 1L of Pyrrolidine for 1kg
2-bromovalerophenone but how many Ethyl acetate do l need to make Alpha-PVP?

2.64848L per kg based on mole density
Mole of 2-b-v=242 grams
Mole of e acetate= 98ml
1. In video, present: ~1 kilo (~700ml) of bromovalerophenone?
2. This proportions are correct? 100g(bk),110ml(pyrrolidine),400ml(EtAc),60ml(distilled water)?
3. In video u adding water at amination stage, but in forum text-message acetone added, what difference?
100g bk,100ml pyrrolidine (~90g) ,400ml EtAc
these are the correct proportions for the AMINATION step
after completion of the reaction add 600ml of water to wash and separate the organic phase
acetone is added before acidification, after the organic layer has been separated from the aqueous layer.
My team is the largest in the CIS countries for the production of such things as salt.
Our main product in cathinones is A-PVP hydrochloride.
Our production technology allows us to complete the entire cycle from start to finish.
All precursors that are practically used are produced by our team.
Bromination is carried out on an industrial scale with the absorption of hydrobromic acid.
The brominated ketone is neutralized and replaced by pyrrolidine.
Then there is the stage of obtaining salt and crystallization.
My product has excellent organoleptic properties and high purity.
We are the power of the chemical industry.
Ready to cooperate with manufacturers and wholesalers.
With us, you can learn how to brominate on an industrial scale or already use ready-made brominated ketones. Increase your production volumes hundreds of times!
Start cooperating with us,
we are the best team from the CIS.
What could i replace pyrrolidine with?
Methylamine. You will get also good product.
And how about the legality of pyrrolidine and 2-bromovalerophenone?
are these watched in europe can i order them safely?
Of course there is no arguing in: "Chemical1 is not listed as illegal." The fact only that it can be used to produce an illegal drug is easily enough to get a full sentence. The good site about it is: When the people catch you, you will have a much worse fate.
I hear in other parts of the world, like Texas, there is about the same. Therefore this neglect here is not understandable.
You wrote quite obvious things. What is a main idea of your message?
Hi! I cant find the proportion of how many 2-bromovalerophenone i need to use,someone can help me?
Amination α-PVP synthesis from 2-Bromovalerophenone
I would like to know if this is correct since I started to buy 1kg of 2-bromovalerophenone then l skipped all the steps and l m not sure of the porpotion but if someone can helping? I can pay it
Ethyl acetate 400 mL
pyrrolidine 87g
2-bromovalerophenone 87g
Is that correct porpotion, guys?
How much methylamine would one use for 1kg of bk ??
262 g is absolute minimum, realistically 280 g - 300 g.
Thats 700 g - 750 g of a 40% MeNH2 solution in water, look at the 4-MMC synth which uses EtOAc for the workup/crystallisation as it won't work as here described for the water.
Thanks everyone gonna try to synth pyrrolidine direct from l-proline and copper carbonate I just have this 55gal drum of 40% laying around one day she find a good use
