摘要： A process for the preparation and separation of para-xylene from mixtures of C 8 aromatic hydrocarbons comprising:

a) the separation by adsorption of the feed mixture into a mixture (I) of para-xylene and ethylbenzene and a mixture (II) of ortho-xylene and meta-xylene;
b) the separation of para-xylene by crystallization of (I) with subsequent distillation in order to obtain ethylbenzene with recirculation of the residue to the crystallization step;
c) the isomerization of (II) after its distillation;
d) the separation of para-xylene from the isomerizate by isomerization;
e) the recirculation of the components, not adsorbed in step d), to the isomerization step.

摘要： A process for the purification of water, in which organic compounds are present which have a solubility in water at 20°C of more than 1 g / 100 ml and which organic compounds contain in addition to carbon and hydrogen at least one oxygen atom and/or nitrogen atom, by contacting said water with a crystalline iron silicate having the following properties:

(a) thermally stable up to a temperature above 600°C,
(b) an X-ray powder diffraction pattern showing, inter alia, the reflections given in Table A:

wherein the letters used have the following meanings:

VS = very strong; S = strong; M = moderate; W = weak;
θ = angle according to Bragg,
(c) in the formula which represents the composition of the silicate, expressed in moles of the oxides, and in which oxides of hydrogen, alkali metal and/or alkaline-earth metal, silicon and iron are present, the Fe 2 O 3 /SiO 2 molar ratio is less than 0.1.

摘要： A process for the separation of para-xylene from a mixture substantially consisting of aromatic hydrocarbons with six to nine carbon atoms in the molecule including para-xylene and ethyl benzene, in which the mixture is contacted with a crystalline silicate with the following overall composition:
y(1.0±0.3)M 2 O.y(a Fe 2 O 3 .b Al 2 O 3 ).SiO 2
wherein M is H and/or an alkali metal
The crystalline silicate is modified by bringing the crystalline silicate into contact with a solution of a salt of a polyvalent, metal whose metal cation concentration is m (in gion/I) and charge density is (R being expressed in nanometres) and wherein the product = m is at least 45,
