Reactions of C3H3+ with Acetylene and Diacetylene in the Gas Phase.
Abstract
The reactions of linear C3H3(+) with acetylene, diacetylene and deuterated acetylene were investigated using a Fourier transform ion cyclotron resonance (FTICR) mass spectrometer. A rate coefficient of (1.4 + 0.7) X 10 to the 9th cc/s was obtained for the reaction of linear C3H3(+) with diacetylene while no production of larger ions was observed with acetylene. Using the ejection capabilities of FTICR, reactions of different C3H3+ precursors with C2H2 were studied in order to investigate possible production of C5H5+ from ionic sources other than C3H3+ present in the reaction medium. Linear C3H3+ isomerized to the cyclic form in reactions with both acetylene and diacetylene. The isomerization was shown to take place via a long-lived C5H5+ complex by isotope exchange reactions between linear C3H3 and deuterated acetylene. Results are discussed in relation to previous work involving C3H3+ reactions and a proposed ionic route to soot formation. Keywords: Fourier transform, Ion cyclotron resonance, Mass spectrometry, Hydrocarbon ions, Soot formation.
