Question

Calculati masa de produs de reactie, trinitrofenol, care se obtine cu o conversie utila de 80% din 1000 Kg fenol de puritate 94%.

Answer 1

3C6H5-OH + 3HO-NO2 --> C6H2-OH(NO2)3 + 3H2O
1000×0.94=940kg fenol pur
n=m/M=940/94=10 kmoli fenol (nt)
Cu=nu/nt×100; 80=x/10×100==>800=100x==>x=8 kmoli
n=m/M==>m=n×M=8×229=1832 kg trinitrofenol [2.4.6-trinitrofenol/acid picric]
