摘要：

The homogeneous, molecular, gas phase elimination kinetics of several tertiary alcohols in seasoned, static reaction vessels, catalyzed by hydrogen bromide at temperatures of 320-392-degrees-C and pressures of 40-174 torr are described. The steric factor appears to be responsible for rate enhancement in the dehydration process. A six-membered cyclic transition state appears to be a reasonable explanation for the mechanism of these reactions.
