hi everyone,
I will synthesize diethyl ether from ethanol and I have a question about how to calculate "yield"
in general terms the procedure is as follows
Ethanol is mixed with sulfuric acid and heated to 140 º C in a simple distillation system
then adding more alcohol will drop by drop
The distillate is put in a fractional distillation system and collected the fractions distilled at 35 º C and 75 ° C
practice procedure indicates that I collect the fraction distilling at 35 ° C and distilled to 75 º C
I think the product is collected at 75 º C must be the alcohol unchanged
I think I must subtract the volume of the collected fraction of the total aggregate volume of alcohol
and from this difference calculate theoretical moless
I think this is because in this case the reaction takes place in a simple distillation system in which part of the distilled alcohol without having a chance to react
%Y = (moles/theoretical moles)x 100
I'm right?
excuse my poor english
