Pozdravljeni fantje, bil sem prati kitajski rjavi prah 2b34m in naredil kristalno čisto steklo
to je, kako je treba videti čisto 2b34m. bil sem narejen v majhnem obsegu.
je samo pokazati, kako je treba videti 2b34m, ker veliko ljudi iz umazanega 2b34m in potem stvar dobijo čist metilon, ampak najprej je treba oprati dober 2b34m in ga narediti čistega, potem dobijo čist metilon, če so naredili dobro sintezo
brat, nisem strokovnjak, ne znam govoriti, samo strokovnjaki na tem forumu lahko opišejo svojo sintezo v kemijskem jeziku. Jaz poznam samo kemijo. Ja, to je moja krivda, rad se hvalim
I think that he dissolved the 2b34m with a non polar solvent, maybe THF, DCM, make some washings with water maybe with bicarbonate, dried the solvent with magnesium sulfate and let it crystallise evaporating slowly the solvent.
I have some 2b34m from china that is brown and didn't obtain high yields. Maybe I will try to purify.
