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.

Abstract: Acrolein (I) is produced by isomerisation of propargyl alcohol (II) in the gas phase at 300-550 deg C and 0.01-50 bar, on heterogeneous catalysts contg alkaline-reacting metal ions (III). Pref (III) contain ions of Li, K, Na, Cs and/or Mg, Ca, Sr or Ba; pref (III) are mol sieves or structurally related Al phosphates contg the above ions, supporting materials doped with the ions, or alkaline earth oxides.

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: C2-C4-olefins are prepared by catalytic conversion of methanol and/or dimethyl ether in the presence of a zeolite catalyst at elevated temperatures, by a process in which the catalyst used is a pure borosilicate zeolite which has been tableted or extruded without a binder and treated with hydrofluoric acid and hydrochloric acid. The treatment of the catalyst with hydrofluoric acid is carried out using 0.001-1N HF, and that with hydrochloric acid is carried out using 3-25% strength acid. The time-on-stream of the catalyst is improved.

Abstract: A process for the preparation of lower olefins from methanol or dimethyl ether by catalytic conversion at from 300 DEG to 550 DEG C. in two stages over borosilicate zeolites, wherein C2-C4-olefins and C1-C4-paraffins are removed after the first reaction stage, the C5+ hydrocarbons are passed to the second reaction stage, the aromatics are removed from the reaction product of the second stage and the remaining reaction products are recycled. The advantage of this process is an improvement in the yield of olefins.
