4-mpp=1,687 mol, HBr=1,69 mol, H2O2=1,262 mol, maximum yield can be 1,262 mol 2b4m or 286 gr, in video 360 gr (1,262 mol 2b4m+0,425 mol mpp)
H2O2+2HBr=2H2O+Br2
Br2+MPP=HBr+2BM4
its mean need 1 eq H2O2 to 1 eq MPP and 1 eq HBr, but in video use more lees H2O2
It's worth to open link under video and read instead of spam to everyone.
8. The second part of discoloration reaction can be conducted for longer time. Hydrogen peroxide is added according with reaction temperature. 9. Reaction mixture is left for a 12 h with a constant stirring at room temperature as soon as all hydrogen peroxide is added.
