Phosgene is an organic chemical compound with the formula COCl 2. It is a toxic, colorless gas; in low concentrations, its musty odor resembles that of freshly cut hay or grass. [7] It can be thought of chemically as the double acyl chloride analog of carbonic acid, or structurally as formaldehyde with the hydrogen atoms replaced by chlorine atoms.
An element–reaction–product table is used to find coefficients while balancing an equation representing a chemical reaction. Coefficients represent moles of a substance so that the number of atoms produced is equal to the number of atoms being reacted with. [1] This is the common setup: Element: all the elements that are in the reaction ...
The main polycarbonate material is produced by the reaction of bisphenol A (BPA) and phosgene COCl 2. The overall reaction can be written as follows: The first step of the synthesis involves treatment of bisphenol A with sodium hydroxide, which deprotonates the hydroxyl groups of the bisphenol A. [6] (HOC 6 H 4) 2 CMe 2 + 2 NaOH → Na 2 (OC 6 ...
Phosgene (carbonyl dichloride, Cl–CO–Cl) is a very toxic gas that is the dichloride of carbonic acid (HO–CO–OH). Both chlorine atoms in phosgene can undergo reactions analogous to the preceding reactions of acyl halides. Phosgene is used a reactant in the production of polycarbonate polymers, among other industrial applications.
The net reaction is as follows: 2 PhOH + COCl 2 → PhOCO 2 Ph + 2 HCl. The use of phosgene can be avoided by the oxidative carbonylation of phenol with carbon monoxide: [2] 2 PhOH + CO + [O] → PhOCO 2 Ph + H 2 O. Dimethyl carbonate can also be transesterified with phenol: CH 3 OCO 2 CH 3 + 2 PhOH → PhOCO 2 Ph + 2 MeOH
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
Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH.It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −.
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 .
