The reaction of an organic substrate with phosgene is called phosgenation. [9] Phosgenation of diols give carbonates (R = H, alkyl, aryl), which can be either linear or cyclic: n HO−CR 2 −X−CR 2 −OH + n COCl 2 → [−O−CR 2 −X−CR 2 −O−C(=O)−] n + 2n HCl. An example is the reaction of phosgene with bisphenol A to form ...
Triphosgene (bis(trichloromethyl) carbonate (BTC)) is a chemical compound with the formula OC(OCCl 3) 2. It is used as a solid substitute for phosgene, which is a gas and diphosgene, which is a liquid. [5] [6] Triphosgene is stable up to 200 °C. [7] Triphosgene is used in a variety of halogenation reactions. [8]
Chemical formula. C 8 H 5 N O 3: Molar mass: 163.132 g·mol −1 Appearance ... A white solid, it is prepared by reaction of anthranilic acid with phosgene. [1] Reactions
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

Thiophosgene is a red liquid with the formula CSCl 2. It is a molecule with trigonal planar geometry. It is a molecule with trigonal planar geometry. There are two reactive C–Cl bonds that allow it to be used in diverse organic syntheses .
Phosgene oxime can be prepared by reduction of chloropicrin using a combination of tin metal and hydrochloric acid as the source of the active hydrogen reducing agent: Cl 3 CNO 2 + 4 [H] → Cl 2 C=N−OH + HCl + H 2 O. The observation of a transient violet color in the reaction suggests intermediate formation of trichloronitrosomethane (Cl 3 ...
Traces of a toxic, colorless gas were found at the headquarters of Sweden’s security agency where a suspected gas leak last week forced authorities to evacuate some 500 people from the facility ...
In chemistry, the rate equation (also known as the rate law or empirical differential rate equation) is an empirical differential mathematical expression for the reaction rate of a given reaction in terms of concentrations of chemical species and constant parameters (normally rate coefficients and partial orders of reaction) only.
