Question

1.Procentul masic de oxigen din 1,2-dipalmitil-3-stearil-glicerol este?

2.Masa de solutie de NaOH de concentratie 24% cu care reactioneaza 221 kg de trioleina este?

Answer 1

CH2 – O – CO – (CH2)14 – CH3
|
CH – O – CO – (CH2)14 – CH3
|
CH2-O-CO-(CH2)16-CH3

MC53H102O6=834g/mol
%O=mO/M*100=96/834*100=11.51%

2. CH2-O-CO-(CH2)7-CH=CH-(CH2)7-CH3    CH2-OH +(CH2)16-CH3-COO-Na+
     |
    CH-O-CO-(CH2)7-CH=CH-(CH2)-CH3  +    3NaOH ->CH-OH + (CH2)16-CH3-COO-Na+
     |
    CH2-O-CO-(CH2)-CH=CH-(CH2)-CH3     CH2-OH + (CH2)16-CH3-COO-Na+


884 kg.......................120 kg
221kg.......................x=30 kg

Cp=md/ms*100 =>ms=md*100/Cp=30*100/24=125 Kg NaOH
