4-MMC (mephedrone) synthesis. Complete video tutorial.

[hazel]

Im can use 31% acid Hcl ?

I can use table salt to get rid of the water in freebase mephedrone??

 

[G.Patton]

no

 

[fuckypu]

Why no if table salt is NaCI ?

 

[G.Patton]

Because it doesn't work - you asked, I answered. MgSO4, Na2SO4, K2SO4 anhydrous are option. NaCl Will not absorb water from extract of amph free base.

 

[fuckypu]

Bro look good on the video they use NaCI= Sodium bicarbonate
the teacher adds the last step of washing the oil Sodium bicarbonate and extracts the remaining water from the oil, who is wrong, you or the teacher?

 

[G.Patton]

NaHCO3 is sodium bicarbonate
It was added in order to get rid of remains of bromine (Br2). Not for drying.

 

[fuckypu]

Sodium bicarbonate, sweat. baking soda, E500b, NaHCO 3 - an inorganic chemical compound from the group of bicarbonates, hydrogen salt of carbonic acid and sodium. Wikipedia

 

[fuckypu]

The mixture is left to stand for a couple of minutes, the rest of the water with the sodium chloride is collected at the bottom layer. This water residue is disposed off. Pure mephedrone free base in benzene is remained in th
sodium chloride what it is
Sodium chloride, NaCl - an inorganic chemical compound from the chloride group, salt of hydrochloric acid and sodium. It is the basic ingredient of table salt, evaporated salt and road salt.

How much 2 bromo 4 methylpropiophenone was produced from the 100G of 4 methylpropiophenone in the video

 

[aaronstevens]

If U already have 2B4M and I am skipping the bromination steps, but I want to have the exact same amount of the other reagents. How much 2 bromo 4 methylpropiophenone will I need

 

[G.Patton]

It is need to change density of water in order to easy separate layers. Addition NaCl is common technique. Do you understand now?

Hello, I only have the methylamine hcl, how can I make a 40% solution. Can i just mix 40 gram white 100ml water

 

[CristalKing]

You can add your methylamine HCL to 2-bromo ...in any solvent and add slowly correct amount NaOH in Water 1:5, then Methylamine HCL will turn in methylamine gas or in Water ....

Can conc. HCl be used for alpha halogenation?


Acid will tautomerize ketone to enol, peroxide will oxidize HCl to elemental Cl2 which is just as good leaving group for N-methylation step. Am I missing something?

 

[G.Patton]

It is better to use elemental Cl2 in gas. I'm almost sure that the yield will be much better.

 

[yin-yang]

Do you have an idea what the yield would be with HCl/ peroxide(have 50%) method? Am trying to avoid cancerous /poisonous chemicals.

 

[G.Patton]

I have no Idea. I'm not sure that the reaction will work as you told because h2o2 will oxidize everything and you can get alcohol instead of ketone or something worse like black sticky oil.

 

[yin-yang]

Did anyone check the final purity of the crystals by GC-MS? Any idea what range might be as crystals won't really grow if there are impuritues present?

 

[Sopranos]

What is the cost of this production - the precursors and stuff - for like 1kg of Mephedrone?
