2
Heat the
substances recovered in step 1) at a temperature just above 86oC.
Substance
should
and when cooled should
back into the liquid state.
3
Use the process of
at a temperature of
to separate substance
from the rest of the mixture.
4
Using
the same process as in step 3) adjust the temperature to
to separate substance
from the rest of the mixture.
5
Using
the same process as in step 3) adjust the temperature to
to separate the water from substance
