Abstract: The present invention relates to a reactor R with apparatus D, the latter comprising a gas- and/or liquid-permeable tray B, in the edge region of which there is disposed a lateral boundary W which fully encloses the tray B and forms a volume V comprising catalytic and/or noncatalytic shaped bodies (F), wherein there is at least one braid made of precious metal and/or base metal on the upstream side opposite the tray B, and the catalytic and/or noncatalytic shaped bodies (F) are selected from (i) shaped bodies (F1) in the form of straight prisms, the footprint of which is selected from triangle, rectangle, hexagon or fragments of these polygons, and (ii) a combination of the shaped bodies (F1) with shaped bodies (F2) that are smaller than the shaped bodies (F1), wherein groups of m to n shaped bodies (F1), m and n being an integer from 3 to 30 with n>m, are framed in a metal cassette open in the upstream direction and closed in the downstream direction by a gas-permeable tray, in a virtually seamless manner with side face to side face and with their longitudinal axis aligned in vertical direction, virtually completely covering the cross section of the tray, to form modules (M), and the modules (M), optionally with cooperation of a joint filler material, with vertical alignment of the longitudinal axis of the shaped bodies (F1), are joined to one another virtually seamlessly in a mosaic-like manner such

Abstract: The invention relates on a process for working-up a nitrous oxide comprising off-gas stream from a production process of adipic acid by decomposing the nitrous oxide contained in the off-gas stream into nitrogen and oxygen in a fixed bed reactor (21) of a N2O decomposition unit (9) at a temperature in the range from 430 to 800° C. to obtain a purified gas, wherein for controlling the N2O decomposition unit (9) a nonlinear model predictive control is used which is based on a reactor model of the fixed bed reactor based on equations of energy transport and species transport for nitrogen, oxygen and N2O.

Abstract: The present invention relates to a method for preparing 2′-O-fucosyllactose, the intermediates obtainable by this method and the use of these intermediates. The preparation comprises the reaction of a protected fucose of the general formula (I) with a tri(C1-C6-alkyl)silyl iodide to give a protected 1-iodofucose followed by the reaction of the protected 1-iodofucose with a compound of the general formula (II), in the presence of at least one base and deprotecting the resulting coupling product to afford 2′-O-fucosyllactose. In this context, the variables are each defined as follows: Ra and Rb are the same or different and are —C(═O)—C1-C6-alkyl, or —C(═O)-phenyl, wherein said phenyl is unsubstituted or optionally has 1 to 5 substituents, or Ra and Rb together are a radical —(C═O)— or a substituted methylene radical —C(RdRe)—, Rc is a radical RSi or is benzyl, wherein said benzyl is unsubstituted or optionally has 1, 2 or 3 substituents, RSi is a radical of the formula SiRfRgRh, where Rf, Rg and Rh are the same or different and are C1-C8-alkyl for example, R1 is a radical —C(═O)—R11 or a radical SiR12R13R14 R2 are the same or different and are C1-C8-alkyl for example; R3 are the same or different and are for example C1-C8-alkyl or both radicals R3 together form a linear C1-C4-alkenyl, which is unsubstituted or has 1 to 6 methyl groups as substituents.
