hello everyone
i have to prepare an epoxyde from the bromhydrin so i have to put 50ml of NaOH(5M) on the bromhydrine so then i will heat the mix at 60°C for 30 minutes so why i have to heat?
then i cool the mix and put 3 times 10 ml of ether (sépration) ( seprate what from what?),, what the ether should do ? so we had two phases, organic phase and aqueous phase, so i think in the organic one we have the epoxyde, right?
but then we have to wash the organic phase with a solution saturated of NaCl, why?
and dry with Na2SO4, why?
sorry for all these questions, i couldn't understand all these things
thank you so much
