first picture after 6 hours leuckart reflux
second picture small amount of this 6 hours long reflux reaction poured inside separation funnel and cold water added to it
can anyone confirm this is good?
why is the n-formyl in separation yellow?
why is it not orange and clear?
should the reaction be run longer?
do you guys use the cooler in position like doing distillation, or just put the cooler on flask and run normal reflux?

You are not doing the first stage of the leuсkart correctly. Your color is not what it should be.
I think in fact you have a minimal amount of n-formylamphetamine in it.
The color should be a rich cognac color.
As I said earlier, the most important thing is to do the first stage correctly.
If you get 90%+ n-formylamphetamine, then the final hydrolysis will give you a huge yield.

Could you please tell me in short what to do in the first stage - turn the condenser to distillation way and distill of all the water slowly?
Then after all the water comes out turn the condenser to reflux setup and do the 6 hour reflux?
Or what am I doing wrong?
Cognac color should mean orange-brown?

Hi @ChingShih did you go further with hydrolysis?
