Question

Cate tone de acid acetic cu partea de masa 80% pot fi obtinute la oxidarea a 11 tone de aldehida acetica?

Answer 1

CH3-CHO + [O] => CH3-COOH
m aldehida = 11 t = 11000 kg
c% acid = 80%
M aldehida = 45 kg/kmol
M acid = 60 kg/kmol
11000 kg aldehida ... a kg Acid
45 kg/kmol aldehida ...60 kg/kmol acid
a= 11000 x 60 / 45=14667 kg acid pur
c= md/ms x 100 => ms= md x 100 / c => ms= 14667 x 100 / 80= 18334 kg = 18.334 t solutie acid acetic 80%
