Impurity alcohols in anhydrous ethanol

2017-04-06 View Original

Thread Content

The anhydrous ethanol purchased by our company contains 100 ppm of impurities such as methanol, propanol, and isopropanol, which affects the purity of the product. Do propanol and isopropanol originate from grain fermentation? Is there anhydrous ethanol produced by other processes that does not contain propanol or isopropanol?

It seems that both propanol and isopropanol will be present.
