    Abstract: La invencion se relaciona con un metodo para producir un flujo de producto que consiste sustancialmente de eteno (flujo de C2=), un flujo de producto que consiste substancialmente de propeno (flujo C3=), un flujo de producto que consiste substancialmente de isobuteno y, opcionalmente de otras olefinas que tiene 4 atomos de carbono (flujo C4=) y un flujo de producto que consiste substancialmente de 2-metil-2-buteno y, opcionalmente de 2-buteno (flujo C5=), y opcionalmente otro flujo de producto que contiene otros hidrocarburos (flujo Cx), que consiste opcionalmente de varios flujos parciales individuales. El metodo inventivo comprende un paso de metatesis que consiste en llevar un flujo de hidrocarburo de C4 que contiene cuando menos 15% en peso de 2-buteno, por lo menos 5% en peso de isobuteno y cuando menos 5% en peso de 1-buteno (flujo de alimentacion) a contacto con eteno en presencia de un catalizador de metatesis usual, el flujo de hidrocarburo asi formado se separa en los flujos C2=, C3=, C4=, y opcionalmente Cx y el flujo C5= se recicla parcial o totalmente en la etapa de metatesis.

    Abstract: The present invention relates to a process for preparing a porous metal organic framework, which comprises the step: Reaction of at least one metal compound with at least one at least bidentate organic compound which can coordinate to the metal, where the metal is ScIII, YIII or a trivalent lanthanide and the organic compound has at least two atoms which are selected independently from the group consisting of oxygen, sulfur and nitrogen and via which the organic compound can coordinate to the metal, in the presence of a nonaqueous organic solvent, with the reaction being carried out with stirring and at a pressure of not more than 2 bar (absolute). The invention further relates to porous metal organic frameworks which have been prepared by this process and their use.

    Abstract: The present invention relates to a porous metal-organic framework comprising AlIII and at least one at least bidentate compound, wherein the at least one at least bidentate organic compound is a six-membered aromatic hydrocarbon ring A in which one or more ring carbons may be replaced by nitrogen and which has three substituents X and optionally one or more substituents selected from the group consisting of R, NRR′, OR, SR, F, Cl and Br, where R, R′ are each, independently of one another, hydrogen, methyl which may optionally be substituted by one or more fluorine atoms or ethyl which may optionally be substituted by one or more fluorine atoms and each X is, independently of the others, C(═O)O−, C(═S)O−, C(═O)S−, C(═S)S− or a protonated form thereof. The invention further provides a process for preparing it and provides for the use of the new porous metal-organic framework.
