I believe they are worried that in the process of esterification of the hydroxyl groups on the glycol you will produce water and with that heat. The heat will also produce toxic vapors. Like any reaction the concentrations are critical.

Subject: [DCHAS-L] Glacial Acetic Acid and Ethylene Glycol incompatibility?


I received a question about storage of ethylene glycol and noticed that a lot of sources specifically mention that ethylene glycol and glacial acetic acid are incompatible.  Can anyone explain why?  I ran this question past our synthesis group and they were of the opinion that in order to get a reaction even with lighter alcohols, the mixture would need to be heated.  Is this an error that has crept into the literature?  I also found a recommendation to store away from xylene.  That has me really puzzled.


My recommendations were to store with other organic acids or to store in secondary containment away from bases and oxidizers.
