Reactions with half-lives of several years

Abstract

The gas-phase thermal decomposition of dimethyldiazirine, (CH₃)₂CN₂, at very slow rates has been investigated using precision gas-volumetric techniques previously applied to second virial coefficient studies. At 50-70° the first-order kinetics correspond to half-lives about 0.3-3.0 years. The present results, together with data obtained by other workers using conventional apparatus at 124-174°, fit a single log rate-reciprocal temperature activation energy equation.
