摘要
The gas-phase thermal decomposition of chlorocyclobutane has been investigated from 394 to 503° In an “aged” reaction vessel, the decomposition is homogeneous and first order, and the rate constant is independent of pressure in the range 28-90 Torr. The primary decomposition proceeds by two paths, one to yield ethylene and vinyl chloride and the other to yield 1,3-butadiene and hydrogen chloride. The Arrhenius equations for the two primary processes were found to be: kethylene = 1014.76 exp(–60,070 cal mol−1/RT) sec−1 and kbutadiene = 1013.61 exp(– 55,240 cal mol−1/RT) sec−1. At times greater than the half-life for decomposition, these products react further. © 1969, American Chemical Society. All rights reserved.
