Ethanol
Ethanol reacts with hydrogen halides to produce ethyl halides such as ethyl chloride and ethyl bromide:
Ethanol
Ethyl halides can also be produced by reacting ethanol with more specialized halogenating agents, such as thionyl chloride for preparing ethyl chloride, or phosphorus tribromide for preparing ethyl bromide.
Chemical derivatives of ethanol
In aprotic solvents, ethanol reacts with hydrogen halides to produce ethyl halides such as ethyl chloride and ethyl bromide via nucleophilic substitution:

E85 in standard engines
This wear, caused by water-contaminated E85, is the result of the combustion process of ethanol , water, and gasoline producing considerable amounts of formic acid (HCOOH, also known as methanoic acid and sometimes written as CH2O2).

Biodiesel
The most common form uses methanol (converted to sodium methoxide) to produce methyl esters as it is the cheapest alcohol available, though ethanol can be used to produce an ethyl ester biodiesel and higher alcohols such as isopropanol and butanol have also been used.
