Mephedrone (4-MMC) Synthesis [2B4M, Ethyl Acetate, Methylamine HCl]

[KFC]

Write on the bottles analytical reagent grade
It is a supplier of equipment for laboratories and chemicals My question is to buy something with high cleanliness or chemicals cheap for Industry

 

[Dr. MMX]

I can not suggest you that. It depends. You can get good reagents for good price, its not necesarry to obtain reagents for analytical purposes.

 

[KFC]

thank you for your help.

 

[Dr. MMX]

Yes this is very good reagent, to ensure maximum precise, but most important is 2b4m, rest matters less

I can never get it to 5.5 !! its always hangs around 7 - 8, then sometimes jumps straight up to 4...
So Annoying... by that time i think it has already mostly all come out of solution anyway, is there any point adding more HCl if solution has already precipitated? at 7 or 8?

hello can be used Erlenmeyer Flask 5000 ml for this synthesize or not ?​

Three necked round bottom Is it mandatory or not?​

 

[Dorov]

Can somebody help me personally to make a good product?
I will pay

are there any major differences when using 40% aq methylamine? 70g of it? does the reaction work same, duration etc?

You can use methylamine 40 % aq. instead of methylamine hydrochloride and NaOH+water solution. In my experience the reaction using 40 % aq is more exothermic compared to adding methylamine hydrochloride into the RM, so add it in portions and monitor the temperature of the RM so it does not go above the range that is best for your reaction and solvent of choice.

 

[norivotset69]

how long does the reaction works? Does the color change is the same like in te video? (brownish means complete)?

 

[dnBQByvHb8Zkawbjpx]

The rest of the reaction is the same and it's going to take the same amount of time as with methylamine hydrochloride, or less.
