Tetraethyl dithiopyrophosphate (also known as TEDP〔 or Sulfotepp〔) is a highly toxic chemical compound with the chemical formula C8H20O5P2S2. The chemical is a mobile oil that is pale yellow-colored and smells like garlic.〔 It is primarily used as an insecticide, but does not damage plants significantly. == Properties == When heated to a temperature that is high enough for tetraethyl dithiopyrophosphate to decompose, it gives off fumes of phosphorus and sulfur oxides, which are highly toxic.〔〔 It can explode if containers of it are heated, and it can burn, although it does not do so easily. The chemical can also polymerize explosively.〔 The chemical also reacts to form toxic and flammable gases in the presence of hydrides and other reducing agents. It is able to corrode iron.〔 When it does this, it can release hydrogen gas.〔 The chemical has a specific gravity of 1.196 at and its vapor density is 13.17 grams per liter at .〔〔 Its melting point is and its boiling point is between and at 2mm Hg.〔〔 The chemical's sorption coefficient is 2.87 Log L/kg. Its Henry's Law constant is 0.000174594 at . Its octanol-water partition coefficient is 3.9804 Log L/kg. Tetraethyl dithiopyrophosphate's diffusion coefficient in air is 0.015 cm2 per second and its diffusion coefficient in water is 0.0000055 cm2. Tetraethyl dipyrophosphate's flash point is and its enthalpy of vaporization is 59.395 kilojoules per mole. Its surface tension is 42.9070014953613 dynes per centimeter. The chemical has no Rule of 5 violations. Its diffusivity in water is 0.63 × 10−5 cm2 per second. It is miscible with a large number of organic solvents, including methyl chloride and acetone and its solubility in water is 30 milligrams per liter at . The alkaline and neutral hydrolysis of tetraethyl dithiopyrophosphate results in the release of ethanol, phosphoric acid, and hydrogen sulfide.
