Can Ammonium Bicarbonate 'salt out' ethanol alcohol?

  1. Dec 18, 2014 #1
    I'm testing Ammonium Bicarbonate in a fermentation process. Is it possible for Ammonium Bicarbonate to 'salt out' Ethanol? Compounds such as Sodium Carbonate and Ammonium Sulfate are able to salt out ethanol.

    Sounds like a good measurement project.

    Does the Ammonium Bicarbonate decompose in the alcohol or is it able go separate the alcohol from the water? As an ionic compound, is it able to 'salt out' alcohol like other ionic compounds?

    Ammonium Bicarbonate = [NH4+][HCO3-]. This will decompose in H2O, I believe... [NH4+] + [HCO3-] --> NH3 (g) + CO2 (g) + H2O (l) [Gas forming reactions tend to go becasue of the large positive entropy change when producing a gas...]
