A method for separating acetonitrile from water, comprising (i) providing a stream Scontaining at least 95 wt.-%, based on the total weight of S, acetonitrile and water, wherein the weight ratio of acetonitrile: water is greater than 1; (ii) adding a stream P, comprising at least 95 wt.-% C3, based on the total weight of stream P, to Sto obtain a mixed stream S, C3 being propene optionally admixed with propane with a minimum weight ratio of propene: propane of 7:3; (iii) subjecting Sto a temperature of 92&#xb0; C. at most and a pressure of at least 10 bar, obtaining a first liquid phase Lessentially consisting of C3, acetonitrile, and water, and a second liquid phase Lessentially consisting of water and acetonitrile wherein the weight ratio of acetonitrile: water in Lis less than 1; (iv) separating Lfrom L

Method for the separation of acetonitrile from water

The invention relates to a process for obtaining a pure aliphatic dialdehyde monoacetal by reaction of the corresponding aliphatic dialdehyde or a precursor of the corresponding aliphatic dialdehyde with one or more aliphatic mono- or polyhydric alcohols while distillatively removing water to obtain a reaction mixture which is separated distillatively, which comprises carrying out the distillative separation continuously in a dividing wall column to obtain pure aliphatic dialdehyde monoacetal as a sidestream from the dividing wall column, or in two distillation columns to obtain crude aliphatic dialdehyde monoacetal as a sidestream in the first distillation column, feed the crude aliphatic dialdehyde monoacetal to the second distillation column and obtain pure aliphatic dialdehyde monoacetal as the sidestream from the second distillation column.

The present invention relates to a process for the preparation of iron-doped ruthenium catalysts supported on carbon, and their use for the selective liquid phase hydrogenation of carbonyl compounds to give the corresponding alcohols, in particular for the hydrogenation of citral to give geraniol or nerol or of citronellal to give citronellol.

Preparation of ruthenium/iron catalysts supported on carbon

A process is described for selectively hydrogenating citronellal to citronellol in which a liquid phase, in which the citronellal is dissolved and particles of a catalyst are suspended which is capable of preferentially hydrogenating carbon-oxygen double bonds over carbon&#x2014;carbon double bonds, is conducted through a device which inhibits the transport of the catalyst particles in the presence of a hydrogen-containing gas.

Method for continuous hydrogenation of citronellal to form citronellol

The present invention relates to a continuous process for the selective hydrogenation of olefinically unsaturated carbonyl compounds to give unsaturated alcohols in particular of citral to give a mixture of geraniol and nerol, in a reactor containing a liquid phase, in which at least one catalyst is suspended, and which can additionally contain a gas phase, wherein the liquid phase and, if present, the gas phase are passed through a device in the reactor having openings or channels.

Selective hydrogenation of olefinically unsaturated carbonyl compounds

The present invention relates to the manufacture of solid materials or shaped bodies containing at least one zeolite and being at least partly crystalline. Furthermore, the present invention relates to the solid materials or shaped bodies as such and to the use of these materials for reactions of compounds having at least one C&#x2014;C double bond with at least one hydroperoxide. Specifically, the present invention relates to a process for the manufacture of a solid material containing at least one zeolite and being at least partly crystalline, wherein the synthesis of the said solid material involves at least one partial step of contacting at least one transition metal oxide source with at least one epoxide or hydrolysate thereof prior to or during the at least partial crystallization of said solid material.
