Very detailed explanation, chemist, I now have 57% hydroiodic acid, red phosphorus, iodine, pseudoephedrine hydrochloride, and distilled water. Can you tell me the addition ratio, reflux temperature and time?

I dont understand why thats way, i just asking because better way for me will be always E+P+H3PO4 85%<+… and heating to 110C and start gradually dropping I according to quantity E in reaction, basically when i filtered reaction to container with toluene or xylen and added mixture NaOh with water so I have that’s same clean freebase what I can filtered from dry NaOh what perfectly absorbed all impurities after 2-3times adding mixture HCl 32%<+ with water for every times shaking and separate smaller part so like that I can do make more beautifully product without recrystallisation BUT GUYS I DONT WANT LOOKS LIKE A BEST SMARTER DUDE ON WORLD ONLY JUST ASKED WHY SO COMPLICATED BECAUSE A NEVER TRYING OTHER METHOD WHAT I KNOW DO IT. peace
