THE BREAKING OF TERNARY ACETATE-ALCOHOL-WATER AZEOTROPES BY EXTRACTIVE DISTILLATION. LLOYD BERG & AN-I YEH
US2176500A Process of concentrating aqueous aliphatic acid solutions by means of seven carbon atom aliphatic esters and five carbon atom aliphatic alcohol entrainers


A rather non exhaustive list of azeotropes related to distillation.
Interesting to note that many high boiling esters form minimum boiling ternary azeotropes with their parent alcohols and water.

Some of these mixtures will be unlikely to occur due to a lower boiling mixture removing all of one of the components.
For instance diacetyl/ethanol should get the vast majority of diacetyl before the diacetyl/water boiling point is reached.

Cool, cheers for that!

nice to find this table on the site lots and lots of reading
You have two ears and one mouth for a reason....
