2) A liquid mixture containing 25 mole% methanol (M), 30 mole% butanol (B), and octylene
(0) is fed to a distillation column. The bottoms product containing 97 mole% O and the
balance M, and 95% of the O in the feed is recovered in this stream. The overhead product
is fed to a second column. The overhead product from the second column contains 95.7 %
of the B in the feed to this column. The composition of this stream is 93 mole% of B and no

i.
the percentage of the butanol in the process feed (the feed to the first column) that
emerges in the overhead product from the second column.
i.
the percentage of methanol in the process feed that emerges in the bottom product
from the second column.
