ABSTRACT A process for the preparation and separation of para-xylene from a mixture substantially consisting of aromatic hydrocarbons with eight carbon atoms in the molecule whereby use is made in the separation of p-xylene of a crystalline silicate as adsorbent, which (a) is thermally stable up to temperatures higher than 600°C, (b) after dehydration at 400°C in vacuum, is capable of adsorbing more than 3 %w water at 25°C and saturated water vapour pressure, and (c) in dehydrated form, has the following overall composition, expressed in moles of the oxides: (1.0+0.3)(R)2/nD. [a Fe203. b A1203. c Ga203]. y(d SiO2.e GeO2), where R= one or more mono- or bivalent cations, a ? 0.1, b ? 0 , c ? 0 , a+b+c = 1, y ? 10 , d ? 0.1, e ? 0 , d+e =1 , and n = the valency of R. and para-xylene prepared by this method.
