1). The analysis of the 1H NMR spectrum will not be very
detailed, as the long chains cause many peaks to overlap. Instead,
create a table with the observed peaks with chemical shift range
(beginning to end of signal). Assign only the distinctive peaks
outside of the alkyl region to the best of your ability. Include
the structure of the methyl ester and label
accordingly.
2).
(a) Use IMFs to explain why biodiesel is immiscible with
methanol, glycerol, and water.
(b) Students used to work up this transesterification in
a separatory funnel. This was very time and temperature sensitive.
It can take several minutes for the glycerol and biodiesel layers
to separate from the emulsion. As the glycerol cools, it begins to
solidify and becomes difficult if not impossible to drain out of
the funnel through the stopcock. Use IMFs to explain why glycerol
causes this stopcock blockage.
