Ethanol, also known as ethyl alcohol or grain alcohol, is the most common alcohol. Its formula is C2H5OH. It is clear and colorless. Ethanol is useful mixed into gasoline because it has a higher octane number than gasoline, reducing engine knocking.
Ethanol is an ingredient in many beverages. It is a mild depressant when ingested. Besides its recreational use, ethanol is important to many industries and food preservation. Ethanol can be produced on Mars using In Situ Resources.
Ethylene can be hydrated to produce Ethanol, although the reverse process, Ethylene production from Ethanol by dehydration, may be more common on Mars. Ethanol may also be produced form CO or CO2 and Water using a copper catalyst and electrolysis.
Recreation and nutrition
Ingestion of excessive ethanol in food or drink causes intoxication. It is a mild depressant, and impairs judgement and reduces inhibitions. Managed use of ethanol may be used to raise morale. Ethanol ingestion may be restricted heavily in a settlement due to the risk to oneself and others.
Ethanol is an effective solvent for many chemicals.
Ethanol is used to preserve fruits and other foods.
