Thermal decomposition of 1-chlorohexane was studied was studied over temperature range 623-833 K and pressure between 5-20Torr. Following rate expression was obtained for homogeneous, non-radical dehydrohalogenation reaction. K(total)=109.84±1.08 S-1 exp-177.25±3.55 (k/mole)RT The observed activation energy and frequency factor was found to be consistent with the elimination of hydrochloric acid via four-member cyclic transition state. The effect of the surface on the reaction was studied at 653.2 K using the packed reaction vessel. It was observed that the reaction proceeds 10% faster in the packed vessel than the unpacked reaction was investigated at 653.2 K. A series of 10 minute’s pyrolysis with initial pressure in the range 5-20torr were made. There was Ca 10.3% increase in the rate of reaction as the pressure was lowered from 20 to 5 Torr.
