Spectral And Kinetic Studies Of The Interaction Of Cyanide And Detergents With Cobalt (Ii) Phthalocyanine In Dmso, Harry M. King Jr.

Masters Theses & Specialist Projects

Spectral and kinetic studies made on CoPc over a concentration range of 1.72 x 10^-6M – 1.00 x 10^-5M in DMSO are consistent with a monomer-dimer equilibrium at 303 K. The dimerization constant obtained at 303 K is 1.67 x 10⁴M^-1 and is two to three orders of magnitude smaller than those of several tetrasulfonated metallophthalocyanines in aqueous solution. The rate constants for the formation and dissociation of the CoPc dimer in DMSO at 303 K are 1.29 x 10²M^-1s^-1 and 7.20 x 10^-3s^-1, …
