Abstract : Subjecting carbon suboxide, C3O2, to electron bombardment in the ion source of a mass spectrometer results in formation of a great variety of positive ions from ion-neutral reactions at sample pressures up to 0.3 torr. Secondary and higher order ions identified include CxO(+) (x = 3,4,5,6), CyO2(+) (y = 3,4,5,6,7,8,9) and CzO3(+) (z = 5,7). From consideration of the pressure dependence of ionic abundances, possible reactions are suggested. Insertion of carbon atoms from C3O2 into reactant ions seems to be an important process. Ion-neutral reactions may provide a path for formation of elemental carbon, but there is no evidence here that they lead to polymerization of C3O2. The rate constant for reaction of C2O(+) with C3O2 is given. (Author)
