Dichlorine carbon monoxide, reaction with

In the PPG-process, chlorine is reacted in a carbon dioxide stream with sodium carbonate to dichlorine monoxide and hypochlorous acid, which is dissolved in water. Reaction with a calcium hydroxide slurry yields calcium hypochlorite ... 

The thermal synthesis of phosgene involves the reaction of carbon monoxide with dichlorine Equation (5.1) induced by purely thermal, as opposed to catalytic (Section 5.1.3), means. 

The extent of thermal dissociation of phosgene at 0.5, 1.0 and 10 bar pressure (0.05, 0.1 and 1 MPa, respectively) has been calculated [1764] based on the accepted ideal gas thermodynamic values [359aa], and is illustrated in Fig. 5.3, whilst the enthalpy of formation for this reaction has been based on actual measurements of the equilibrium constant in the temperature range of 645-725 K by heating together carbon monoxide and dichlorine [218], see Section 6.1. The equilibrium reaction depicted in Equation (5.1) has been measured experimentally both by dissociation of phosgene and by association of carbon monoxide and dichlorine [216]. At 603, 553 and 503 C, the dissociation was found to be 91, 80 and 67%, respectively, in reasonable agreement with the values based on the ideal gas calculations illustrated in Fig. 5.3. At temperatures above 800 C, the dissociation is essentially complete [216]. 

The reaction of CCl with CO is reported to result in the formation of considerable quantities of phosgene [1824a], and it is interesting to speculate upon the carbon monoxide behaving as a thermodynamic sink for dichlorine in the well-known and industrially operated reaction [2165] ... 

The reaction of carbon monoxide with lead(II) chloride is illustrated in Table 5.2 [168]. Thermal decomposition of the lead salt to give dichlorine, followed by reaction with carbon monoxide, could be responsible for the phosgene formation [781]. 

In the reaction of sulfur(II) chloride with carbon monoxide, the co-product S2CI2, formed in addition to phosgene, may be reconverted using dichlorine into active SClj [142],... 

In the reactions of carbon monoxide with copper(II) chloride, nickel(II) chloride or silver(l) chloride, thermal decomposition of the salts to give dichlorine, followed by the... 

The most investigated com X>und is CeOCl, studied both as a pure material and as a compound formed in situ in the reaction of CeOj with phosgene it has been suggested (although it seems rather unlikely) that reaction between CeOCl and COClj does not actually occur, but that the product derives from equilibrium amounts of carbon monoxide and dichlorine present [307,1087,1088]. The reaction of PrOCI with phosgene has also been the subject of a kinetic study [305]. 

As is common for many of the reactions with metal oxides and phosgene, the reaction rate goes through a maximum at ca. 650 C, drops to a minimum at ca. 850 C, and then starts to rise again (see Fig. 9.10). This is reasonably explained in terms of phosgene dissociation into carbon monoxide and dichlorine (see Chapter 8) becoming appreciable at above 600 C,...
