Abstract: O.Z. 0050/034743 A process for the preparation of a crystalline aluminosilicate of the pentasil type by hydrothermal crystallization of SiO2 and Al(OH)3 in the presence of an alkali metal salt at from 80 to 250.degree.C, wherein the crystallization is carried out in ether or aqueous ether. Particularly suitable solvents include the ethers from the group of the poly-(ethylene glycol) dimethyl ethers and mixtures of these ethers with water. The use of these crystalline aluminosilicates as catalysts for alkylating aromatics, and for preparing olefins and/or aromatics from methanol and/or dimethyl ether is also described.

Abstract: But-2-enes are obtained from C4-hydrocarbon mixtures which contain but-1-ene and may or may not contain but-2-enes by catalytic isomerization of the but-1-ene to but-2-enes in an isomerization zone at elevated temperatures by a process in which the isomerization is carried out in combination with a distillative separation zone, the said hydrocarbon mixture being fed to the isomerization zone and/or distillative separation zone, the isomerization mixture obtained from the isomerization zone is passed into the distillative separation zone, a but-1-ene-containing fraction is removed above the lower third of the distillative separation zone and passed into the isomerization zone, and the but-2-enes or a fraction containing these are or is removed in the lower third of the distillative separation zone.

Abstract: The invention relates to a process for the valence isomerization of an olefin in the presence of a catalyst at elevated temperatures, wherein the said isomerization is carried out in the presence of a pentasil-type zeolite as the catalyst. It is possible with this process to achieve better times-on-stream and selectivities of the catalyst than can be obtained with the conventional processes.
