The demand and prices depend on the volume of purchases of the wholesale of raw materials and your region. This synthesis is well suited for production in large quantities (ton per month and more)

Mr William please does mephedrone look very much like cocaine and does it have the same effects? And if it is put in the tongue it causes the tongue to be like cocaine? thank you.

In point 8, I add 20L of ice-cold acetone to the reactor and only separately add HCL 36-38% slowly until the pH drops to 5? Do I mix the HCL with 20L of acetone and only add the mixture to the reactor?

I can't figure out why during acidification the whole thing precipitates nicely until at some point it starts turning blue....

I bet it is due to adding too concentrated HCL 36-38% by which I burn the product and hence the blue mess.

You are dropping the pH to 5. That is too low! The procedure says only drop to 5.5 - 6. Next time, bring the pH to the correct range and see if you have blue then!

@Heineken thanks for the reply :
I have couple other questions : 2-Bromo-4'-methylpropiophenone is available in market, but not available to deal in small sizes, any way around it ?
and can we do this reaction creating a home made stainless steel batch reactor using heating rod, thermocouple and a pressure guage into it. there is no available equipment available
of size without drawing attention, please guide if you know some tips

thanks in advance

can 2-iodo-4-methylpropiophenone be used in place of 2-Bromo-4'-methylpropiophenone?
