## 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.

H2S increases the thermal isomerization of butene-2 cis (B,) to butene-1 (B1) and butene-2 trans (Bt) around 500Β°C. This effect is interpreted on the basis of a free radical mechanism in which buten-2-yl and thiyl free radicals are the main chain carriers. B1 formation is essentially explained by th
