Abstract

The values of the rate constants of the triangle scheme, calculated by means of a non-linear least-squares method, depend systematically on the HCl concentration. The alteration of the cis-trans selectivity expressed by the ratio k1c/k1t might indicate a change in the mechanism of isomerization with the HCl concentration.

Abstract

Значения постоянной скорости треуголной схемы, определенные нелинейным способом приближения, изменяются систематически в зависимости от концентрации хлористого родорода. Изменение цис-транс избирательности, выраженное как отношение k1c/k1t, указывает на изменение механизма изомеризаций с концентрацией хлористого водорода.
