Question

Se obtine trinitrotoluen prin nitrarea toluenului . scrieti ecuatia si.calculati masa de toluen care trebuie nitrata cu acidul azotic din 200 g amestec nitrant in care acidul azotic are concentratia 31 %

Answer 1

M, toluen= 92g/mol

M,HNO3=63g/mol

c=mdx100/ms=>md=cxms/100=31x200/100g=62gHNO3

1mol...................3mol    SAU in grame

C6H5-CH3 + 3HONO2---> C6H2(NO2)3-CH3+3H2O

92g......................3x62g

x..................................63g

x=m,HNO3=.........................CALCULEAZA !!!!!
