    Description / Table of Contents: Abstract Используя соответствующую реакционную модель, смещение двойной связи пропилена на фаязитных цеолитах, протекающее по трем возможным механизмам, обсуждается теоретически. Энергетические кривые были рассчитаны с помощыю расширенной терии Хюккеля. Критически обсиждаются результаты теоретических приближений.
    Notes: Abstract Using an appropriate reaction model, the double bond shift in propene on faujasite zeolites proceeding via three possible mechanisms was theoretically treated. The energy curves were calculated by means of the extended Hückel theory. The results of the theoretical approach are critically discussed.

    Description / Table of Contents: 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.
    Notes: 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.
