Hello everyone
I would like to know if everybody who tried this route of synthesis get a clear white product ?
I have to wash it Everytime after putting HCL acid inside
when I put icecold Aceton inside the reactor, It becomes dark red color
does anyone know about this problem
good work Dr.MMX
a very easy structure and easy to understand for everybody who want to learn

acetone cant t be added like "all at once", must be ice cold, should be stirred.
You could have already by products in the freebase from the reaction, it oculd be too long, it could bee to short. Washing could be not ok. I never had red color yet so I cant really tell, as well I cant really tell anything as long there is no details. I can only suggest reading all ofthe post of the section and the best finding mistakes urseslf
compare with other user's results

I try to explain exaxtly next time
While I add hydrochloric acid (I stir throughout the entire precipitation process and I also used ice-cold acetone -20 degrees) the acetone/freebase mixture changes color I even think I found the error methylamine and 2b4m not fully reacted Blue-green spots remained in the reactor itself after the failure I have 1000 gr 2b4m, 5L ethyl acetate, 2L 50% caustic soda and 1500 gr. Methylamine HCL used The methylamine was added in 3x 500 g increments, which led to a prolonged reaction could probably be related to that
