Hi, does anyone know what is the best way to get N-methylpyrrolidone? This is the only thing missing to try this route. thank you in advance. Please PM me if you would not like to share sources in public. Any help would be appreciated guys.
I found in Russian 4 methlypropiophenone in liquid cas not dry is it can be the same. or can I get the right cas number of 4 methylpropiopheone . Which I need

Sorry sir for directly message
Actually I synthesis of mephedrone hydrobromide. All process i done last process when liquid of mfd i kept in freezer from last 48 hr but meph not make dried and solid. When I filter them use of butchner funnel all liquid are same condition. There no solid form left
Main problem is that liquid is in oil base form. How i seperate oil base form from meph liquid. That is my problem . Other wise I don't disturb you sir
I think the vacuum is just used, because it is officially in the manual of the reactor to supply liquids with the help of vacuum. The reaction would be the same without vaccum.
Where would you suggest to sourse this from (for shipping to EU) And the other reagents for this synthesis to. Are chinese vendors good to look into. Maybe even Alibaba…?

I do everything according to the film. after separation, I drain the oil from the top layer into a cold beaker, then add 500 ml of frozen acetone and the color starts to change to red and more and more bloody. Ph at this point is around 8.
After gradually adding hydrobromic acid 48%, the elixir begins to change into a dark color, and then, after adding further drops and obtaining a PH between 4-5, the color becomes slightly reddish brown. There is no precipitation reaction of mephedrone salts from the solution at all. The solution is still liquid. what could this be caused by?
