3-CMC Synth for a Newbie

[Jesse_Pinkman_]

so, my experience is,
100g 2b3c
300dcm
200methylamin40% aqua
3 hours stirring
I use a sealed glas 1,8l, put foil between lid and glass so that nothing smells or gas escapes.
After reaction took place
2 times washing with dest.water
1 time extract water phase with dcm
put into rm,
add same amount fresh water into rm
put on magnetic stirrer
acidificaction drop by drop till ph6, about 50-55ml HCI,
after that take the water layer,evaporate , let it crystallize, takes some time
opt. rotovap till 50% of the water is gone, then air drop


ethylacetat is possible, takes only 20 min, no heating necessary, rest same prosedure like with dcm

Hi I'm very glad you are sharing your experience I have a few questions

What is the efficiency of this method ?

Is it possible to transfer it to plastic barrels to scale up to kilograms of finished product if so how to do it ?

For the help received, I will be happy to repay you when everything at my place starts greetings

What is 2b3c? I got everything else but I'm not sure about what that is. Sorry if this is a dumb question
