Trinitroethylorthocarbonate

Trinitroethylorthocarbonate also known as TNEOC is an organic compound with the chemical formula C(OCH2C(NO2)3)4. It is an oxidizer with excellent chemical stability. Its explosion point is 238 °C, and it begins to be decomposed at 200 °C. Its explosion heat is 5.797 J/g and specific volume is 694 L/kg. Its structure is closely related to that of trinitroethylorthoformate (TNEOF). Both are highly explosive and very shock-sensitive, and may be dissolved in nitroalkanes to reduce their shock-sensitivity.

Synthesis
Trinitroethanol reacts with carbon tetrachloride under a catalyst of FeCl3.
