Conclusions
-
1.
With increasing pressure in the liquid phase, significant decreases occur in the rates of monomolecular and chain decomposition of dicyclohexyl peroxydicarbonate (CPC) in toluene, benzene, and acetonitrile.
-
2.
The change in the rate constant of monomolecular decomposition of CPC at atmospheric pressure in a series of solvents is due to changes in magnitude of the electrostriction parameter and viscosity.
-
3.
At pressures corresponding to the region of existence of the solvent (benzene) in the solid phase, the homolysis of CPC, up to high levels of conversion, is described by a first-order equation; the effective rate constant of the reaction is 1.5 times that calculated for the liquid phase.
