✦ Synopsis

The position of abstraction by H atoms from ethylene, propylene, butene-1, and cisand trans-butene-2 and the rates of abstraction relative to addition have been measured at 25Β°C.

From ethylene, abstraction relative to addition was 5 3 X lo-*. For propylene, butene-1, cis-butene-2, and trans-butene-2, abstraction occurred on 0.27'0, 1.6%, 1.570, and 0.9% of the reactive encounters, if disproprotionation-combination ratios for ally1 and alkyl radicals are similar to those for alkyl-alkyl pairs. Only allylic abstraction was observed.

## Abstract An analytical and kinetic study of the thermal reaction of __cis__‐ or __trans__‐2‐butene has been performed in a static system over the temperature range of 480–550Β°C and at a low extent of reaction and initial pressures of 10–100 torr. The rate constant of the unimolecular __cis–tran
