The Thermodynamics of Gaseous Cuprous Chloride, Monomer and Trimer¹

Towards integration of hydrolysis, decomposition and electrolysis processes of the Cu–Cl thermochemical water splitting cycle

“…Table 6 presents the CuCl vapour pressure [28] and the quantity of CuCl entrained with oxygen gas at various hydrogen production scales and operating temperatures. The loss of CuCl will accumulate significantly to several tonnes per day if the entrained CuCl is not recovered.…”

Phase equilibrium diagram for the tin(II) bromide-copper(I) bromide system

“…The obtained material changed its appearance during a few hours in the air, so it had to be stored under vacuum. It is rather surprising that distilled copper(I) bromide is relatively unstable in the air, whereas distilled copper(I) chloride was not affected during several days as reported by Brewer and Lofgren [4]. It has been observed, however, that very thin white layers of CuBr sometimes deposited during distillation did not change colour even after a month.…”

Thermogravimetric analysis of InCl3 sublimation at atmospheric pressure

“…By increasing the temperature to its boiling point (i.e., 1632 K at 1 atm), only 11% monomer was detected. No Cu 2 Cl 2 or other compounds were reported [35]. Similarly, electron-diffraction studies reported by Wong and Schomaker showed that above its melting point (723 K) the primary gas-phase compound was Cu 3 Cl 3 [34].…”

“…Brewer and Lofgren [35] studied the equilibrium vapor composition and thermodynamic properties of Cu x Cl x . An anhydrous cuprous chloride was prepared from metal copper and anhydrous hydrogen chloride passing through a quartz tube at 1073-1273 K,…”
