HYDRODECHLORINATION OF 1,2,4-TRICHLOROBENZENE

Abstract

            The adsorption properties of 1,2,4 - trichlorobenzene (TCB) and hydrogen chloride on Ni / -Al2O3 and Ni / expanded clay, catalysts for the hydrodechlorination of chlorobenzenes, were studied. It has been established that the surface treated with hydrogen is able to absorb 1,2,4 - TCB and hydrogen chloride more than the surface treated with nitrogen.

            The most controversial issue in periodic publications is the mechanism of the reaction of hydrodechlorination of chlorine-containing aromatic compounds. This is all the more important because, depending on the composition of the catalytic system, the mechanism of the hydrodechlorination reaction changes significantly [1, 2].
