re column temperature
- hi Steve
For a still with a reflux column you shouldn't let the tempurature go
above 80 because you will start to get propanol at 82. i am guessing
the other still you where refering to was a pot still which would
explain why they say 90 because pot still's don't get much separation
so you have to increase the tempurature to get adiquate amounts of
in case you wanted to know the boiling points of several liquids
which will be in the wash are as follows
so assuming that this new still has a reflux column which will
separate these different substances quite well. You should have to
top of the column at 70 and throw all of that stuff away because it
will be mostly methanol. After this run the still at 79 or 80 untill
all of the ethyl alcohol (the good stuff) is bottled.
you should be able to tell when all of the alcohol is gone because
the temperature will jump up several degrees.
i hope i have been some help.
