Triphosgene (bis(trichloromethyl) carbonate (BTC), C3Cl6O3) is a chemical compound that is used as a safer substitute for phosgene, because at room temperature it is a solid crystal, as opposed to phosgene which is a gas.Triphosgene crystals decompose above 200 °C.
TPP is a highly efficient product that serves successfully in many applications, for example:
in vitamin synthesis and production of pharmaceutical active ingredients, crop protection products and coatings.
