Speciation of C_6H_6 Isomers by Gas Chromatography-Matrix Isolation Fourier Transform Infrared Spectroscopy-Mass Spectrometry

摘要

Isomeric C_6H_6 species produced by high-pressure shock tube pyrolysis of 1,5-hexadiyne have been investigated by gas chromatography-matrix isolation FTIR spectroscopy-mass spectrometry. In addition to benzene (stable end product) and 1,5-hexadiyne (starting material), six isomeric C_6H_6 species have been identified on the basis of spectroscopic characteristics. The results are consistent with theoretical predictions of stable species that will be formed in the pyrolysis of 1,5-hexadiyne and key species have been positively identified for the first time.
