An ester can be synthesised from an intoxicant and an organic venereal disease. Synthesis of organic molecules needs specific conditions. In fellowship to purify the growth you need to consider the differences in properties of the organic molecules involved.
The organic acid we impart use will be acetic acid (CH3COOH) and ethanol (C2H5OH).
Questions and answers
What catalyst is employ in the reaction?
H+ from sulphuric acid H¬2SO4.
Which reactant is limiting?
m(ethanol)=10×0.789×0.95?7.4955 g
m(acetic acid)=10×1.049×0.99?10.4 g
M(ethanol)=46.026 ?gmol?^(-1)
M(acetic acid)=60.024? gmol?^(-1)
n(ethanol)=7.4955/46.026?0.1628 mol
n(acetic acid)=10.4/60.024?0.17326
n(acetic acid)>n(ethanol) Meaning ethanol is limiting.
regard the yield?
m(ester)=8.64 g
M(ester)=88.048 ?gmol?^(-1)
n=8.64/88.048?0.098 mol
Since the ratio between the limiting reactant and ester is 1:1 they have the same amount. So these are the suppositious calculations.
n(ester)=0.1628 mol
M(ester)=88.048 ?gmol?^(-1)
m=0.1628×88.048=14.33
percentage yeild=(experimental yeild)/(theoretical yeild)×100=8.64/14.33×100?60.3%
The reaction is at equilibrium with Kc approximately 4. What substances do we have in the rb flask when heating is turned off?
Do we need to add more substances in the fact elude?
Ethanol, Ethnoic acid, Sulphuric acid and some ester, no because the sulphuric acid is a catalyst and is not consumed or does not react.
In this practical we use our knowledge about Le Chateliers principle to increase the yield. What do we do, in terms of Le Chateliers principle to increase the yield?
By removing the product (ester), you will shift the equilibrium to the right.
To separate the substances we need differences concerning properties. In this practical we separate by distillation. What property is used for time interval by distillation?
The substances boiling points
