    Abstract: Die Anmeldung betrifft ein Verfahren zur Herstellung von C2- bis C4-Olefinen durch katalytische Umsetzung von Methanol und/oder Dimethylether in Gegenwart von Borosilikatzeolithen bei erhöhter Temperatur, bei dem man als Katalysatoren reine Borosilikatzeolithe verwendet, die ohne Bindemittel tablettiert oder verstrangt und mit Salzsäure behandelt wurden. Die Salzsäurebehandlung der Katalysatoren kann mit 3 bis 25 %iger Säure durchgeführt werden. Die Laufzeit der Katalysatoren wird verbessert.

    Abstract translation: 本申请涉及一种用于生产C2至C4烯烃通过在硼硅酸盐沸石的存在下,在升高的温度下,该方法包括使用纯作为催化剂的硼硅酸盐,没有粘合剂或压片挤出,并用盐酸处理甲醇和/或二甲醚的催化反应 是。 催化剂的盐酸处理可具有3至25%的盐酸来进行。 催化剂的长期改善。

    Abstract: A silver catalyst containing lithium and cesium as promoters for the direct oxidation of ethylene with oxygen to give ethylene oxide is applied to a porous carrier and essentially consists of alpha -alumina and contains certain amounts of soluble calcium, aluminum, potassium and sodium salts. The carrier has a BET surface area of from 0.4 to 0.8 m2/g, a pore volume of not less than 0.45 ml/g, the pores being equally accessible to cold and warm water, a bulk density of less than 700 kg/m3 and a shape which, in the reactor, provides a geometrical surface area of not less than 600 m2/m3, on which more than 13% by weight of silver are applied as active component and more than 115 kg of silver are available per m3 of reactor, and from 100 to 300 ppm by weight of lithium and from 200 to 600 ppm by weight of cesium are present as promoters. A process for the preparation of the silver catalyst and its use for the oxidation of ethylene are described.

    Abstract: Cyclopentanone is prepared from adipic esters by reacting adipic esters of the formula R1OOC-(CH2)4-COOR2 where R1 and R2 are alkyl of 1 to 12 carbon atoms, cycloalkyl of 5 or 6 carbon atoms, aralkyl or aryl and R2 can additionally be hydrogen, in the gas or liquid phase at from 150 DEG C. to 450 DEG C. in the presence of zeolitic catalysts and/or phosphate catalysts, preferably zeolites of the pentasil type.
