✦ Synopsis

The thermal decomposition of trimethyl aluminum on different hot substrates has been studied under low-pressure conditions. The products of the decomposition reaction were analyzed mass-spectrometrically using electron-impact and resonance-enhanced multiphoton ionization. The results of this study reveal that only CH 3 appears as a gas-phase product and stable compounds such as CH 4 and C 2 H 6 are not observed under the conditions employed. The apparent activation energy for the production of the CH 3 radical from the Al-coated hot substrates is measured to be 11 + 2 kcal/mole.
