Question

Oblicz ile kilogramów mydła i gliceryny powstanie w wyniku zmydlenia 10 kg tristearynianu gliceryny roztworem wodorotlenku sodu.

Answer 1

C₃H₅(COOC₁₇H₃₅)₃+3NaOH⇒ C₃H₅(OH)₃+3C₁₇H₃₅COONa

10kg                                              x                           y

 

 

mC₃H₅(COOC₁₇H₃₅)₃=684+110+96=890u

mC₃H₅(OH)₃= 92u

3mC₁₇H₃₅COONa=648+105+96+69=918u

 

890u----------10kg

92u------------x

x=1kg gliceryny

 

 

890u----------10kg

918u------------y

y=10,3kg mydła
