HIGH PRESSURE ION-MOLECULE REACTIONS IN CARBON MONOXIDE AND CARBON MONOXIDE-METHANE MIXTURES.

In carbon monoxide at pressures above 0.2 torr, the principal produce ion is C2O2 formed by a three-body process. Above about 0.8 torr, the reaction appears to approach equilibrium with an equilibrium constant of 1.95torr. At pressures of methane above 0.2 torr and small additions of CO, the only reaction observed is the protonation of CO by CH5 with a rate constant and are not observed. At pressures of carbon monoxide above 0.2 torr, the addition of small amounts of methane results in an H atom transfer reaction to CO. In addition, C2O2 reacts to form HCO, C2H3O, and C3H3O. Author
