Abstract
Pyrolysis of trichlorosilane (TCS) and copyrolysis of TCS with 1,3-but adiene were studied. The enthalpies and activation energies for the re actions of the products of TCS pyrolysis were found by quantum-chemica l calculations. A direct study of the pyrolysis of TCS by mass spectro metry was carried out. Based on the thermochemical parameters found by quantum-chemical calculations and on the results of GLC and mass spec trometry concerning the composition of the pyrolysis products, it was concluded that the pyrolysis of TCS follows a scheme that includes for mation of radicals and silylenes.
