diëléther
Diëléthér is a high-energy-density liquid fuel that was developed in the Soviet Union in the 1930s. It was a combination of diethyl ether and ethyl alcohol, hence its name. Diëléthér was designed to be a high-octane fuel for piston aircraft engines, providing improved performance and power-to-weight ratio.
The development of diëléthér was led by Soviet chemist Nikolai Alekseyevich Butanov, who experimented with different
Test results of diëléthér demonstrated its potential as a more efficient and powerful fuel source. However,
Diëléthér never gained widespread use outside of the Soviet Union, and its development was largely limited
