Abstract
Abstract Vacuum pyrolysis of trichloroacetyl chloride was studied at 970–1370 K by mass spectrometry and matrix isolation-IR spectroscopy. The pyrolysis experiments were performed in a quartz flow reactor directly connected to the ion source of a quadrupole mass spectrometer or to an optical helium cryostat. The IR spectra of the pyrolysis products, condensed at 12 K in an argon matrix, have revealed the intermediate species: radicals CCl 3 and COCl, carbene CCl 2 and unstable ketene Cl 2 CCO. It has also been established that the COCl 2 , (COCl) 2 and C 2 Cl 4 detected are formed in secondary reactions. On the basis of the experimental data obtained, two possible routes for the thermal dissociation of CCl 3 COCl are proposed, including molecular and radical mechanisms.
