Ecuatia se scrie mai simplu:
C6H6O + aHNO3 -> C6H6-aO(NO2)a + aH2O
Mcompus=12*6+6-a+16(12+32)a=45a+94
45a+94...............100%
14a................15,217%
45a+94=1400a/15,217=92a
47a=94 => a=2
e vorba de dinitrarea fenolului
C6H6O + 2HNO3 -> C6H4O(NO2)2 + 2H2O
amestec nitrant: HNO3/H2SO4
b)
94/100=36,8/mteoretica => mteoretica=36,8*100/94
94kg............................184kg
C6H6O + 2HNO3 -> C6H4N2O5 + 2H2O
x=?...............................36,8*100/94
x=36,8*100*94/184*94=20kg fenol pur
95/100=20/Vimpur => Vimpur=20*100/95=21,05kg fenol impur
