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.^{[citation needed]} 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.^[1] 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.^[1]
