yes, when i've buyed it from China vendors i was mixed pyrrolidine with 2-bvp and get a-pvp Free base (with no other substances). it can be used for smoking, drinking and injecting
photo #1 2-bromovalerophenone with ethylacetate (my 2-b-vp is crystallized after halogenation may be it problem? but what i do wrong? maybe HBr is too concentraded? but after EtAc added it dissolved)
...
photo #2 decolorized and spoiled after 4-5 drops added of pyrrolidinen to Rm from Photo #1...
After water added at halogenation stage, i have that...
My questions:
1. What i do wrong?
2. It must be dropped out, or i can "save" expensive valphen (#1009...)?
thnx!
p.s. i'am mixing in hands, because my magnet stirrer can't mix it properly (small quantity of liquids)
but,,,, colors...
hmmm, how i can calculate acetone size (ml) (crystalization stage, after water layer was removed) and (~ ml) of hydrohloric acid (not to over-acidify the solution)?
1. In video, present: ~1 kilo (~700ml) of bromovalerophenone?
2. This proportions are correct? 100g(bk),110ml(pyrrolidine),400ml(EtAc),60ml(distilled water)?
3. In video u adding water at amination stage, but in forum text-message acetone added, what difference?
