Abstract

Dehydrogenation process for the preparation of 2,5-dianylidoterephthalic esters by dehydrogenation of 3,6-dihydro-2,5-dianylideterephthalic esters with air, characterized in that the dehydrogenation is carried out in the presence of such a quantity by weight, of an aromatic amine as a diluent, corresponding at least to the amount by weight of the substance to be dehydrogenated, for which purpose it is possible to use, if necessary, even further diluents, the amount by weight of which, however, should at most be so large as the amount by weight of the aromatic amine.
