Question

prin clorurarea fenolului se obtine insecticidul 2,4-diclorofenil. Calculeaza cantitatea de insecticid(Kg) obtinuta in 500 Kg fenol de puritate 94% si volumul de clor utilizat in conditii normale

Answer 1

C6H5-OH + 2Cl2 => (Cl)2-C6H3-OH + 2HCl


0,94*500=470kg fenol


n=m/M=470/94 = 5 kmoli fenol


1 kmol C6H5-OH.......163 kg insecticid

5 kmoli............x=815 kg insecticid


1 kmol fenol........2*22,4m3 Cl2

5 kmoli fenol.......x=224m3 Cl2
