Abstract

The apparent kinetic parameters for the dehydrohalogenation of 1-bromo-2-methylpropane to isopropylene on alumina modified with alkali halides have been calculated. Both true and apparent kinetic parameters give kinetic compensation effects, with different coherence of the ΔH≠v.s.≠ΔS≠ points. This leads to useful conclusions about the fitness of the two kinds of parameters for handling surface reaction mechanisms.

Abstract

Были рассчитаны кажущиеся кинетические параметры дегидрогалогенирования 1-бром-2-метилпропана до изопропилена на окиси алюминия, модифицированной щелочными галидами. Как для как действительных, так и кажущихся кинетических параметров был обнаружен кинетический компенсационный эффект с различной когерентностью ΔH≠ и ΔS≠. Это приводит к ценным заключениям относительно пригодности этих двух типов параметров для описания механизма реакции на поверхности.
