Abstract: Prepn. of N-heterocycles of formula (I) and (II) in which R1 and R4-R9=H, alkyl, aryl, aralkyl, alkaryl or cycloalkyl gps., and R2 and R3=alkyl, alkaryl, substd. alkyl or cycloalkyl gps. The prepn. is characterised by reaction of olefins of formula (III) and (IV) (in which R2-R9 are as above) with NH3 or a prim. amine of formula H2NR1 in which R1 is as above, in the presence of a zeolite catalyst.

Abstract: The invention relates to a process for the preparation of a catalytically active mass of the formula… Mo12Bi0.1-10Fe0.8-12(Co,Ni)0.1-10P0-2A0-10B0.001-1OX,… in which A represents the elements arsenic, antimony, zinc, thallium, tungsten, alkaline earth metals, zinc and/or chromium, B represents at least one of the metals sodium, potassium, rubidium, caesium and/or indium and X represents numbers determined by the atomic valencies of the individual elements, in which the iron and molybdenum fraction is introduced wholly or partially in the form of a dried powdered iron molybdate gel to an aqueous solution or suspension of the other components and the mixture, with stirring and possibly heating, is brought to a gel-like solidified state, then comminuted and dried at elevated temperature and finally calcined.

Abstract: A process for the preparation of mixtures of isomeric cresols with a molar ratio of para- to meta-cresol of from 0.6:1 to 10:1 by isomerization of cresol mixtures or ortho- and/or metal-cresol on zeolite catalysts of the pentasil type in the gas phase at from 300 DEG to 600 DEG C. under from 0.01 to 50 bar entails the mean particle size of the zeolite catalyst being at leat 3 mu m, and the selectivity in the established test for the disproportionation of ethylbenzene to diethylbenzene isomers being at least 60% for para-diethylbenzene.

Abstract: Medicinal white oils and medicinal paraffins are prepared from petroleum fractions containing aromatics and nitrogen, oxygen and sulfur compounds, e.g. light and heavy atmospheric gas oils, vacuum gas oils and residues, which have been pretreated in a first stage by acid treatment or catalytic hydrogenation, by hydrogenation in a second stage over a nickel-containing catalyst under from 50 to 200 bar and at elevated temperatures, by a process in which the catalyst used in the second stage and present in the oxide form is reduced with a hydrogen-containing gas, passivated and then again activated with hydrogen, before the hydrogenation to medicinal white oils or paraffins is carried out.
