[Nhcoll-l] off-coloured EtOH

[Haff, Tonya (NCMI, Crace)]

Hi again,

On a separate topic, I wonder if any of you have had any experience with unused EtOH developing a yellowish colour? We had this happen to a freshly made batch of 70% EtOH recently, and none of us are clear on what happened or if this is a problem or not.

Thanks,

Tonya
