Patent number: 10196327Abstract: The invention is concerned with the production of 1-hexene and octenes from ethene. 1-Butene is optionally also to be produced. The problem addressed by the present invention is that of developing a process for producing 1-hexene from ethene by MTHxE etherification to achieve better chemical utilization of the employed carbon atoms. This problem is solved by catalytic retrocleavage of MTHxE into the C6 olefins and the alcohol, reuse of the alcohol in the etherification and reaction of the obtained C6 olefins with ethene to afford C8 olefins. In this way the alcohol is not lost from the process but rather is internally recirculated as a derivatizing agent. The less attractive C6 olefins from the cleavage product are upgraded to octene with further ethene in order to provide a further commercial product.Type: GrantFiled: June 15, 2017Date of Patent: February 5, 2019Assignee: Evonik Degussa GmbHInventors: Guido Stochniol, Helene Reeker, Dietrich Maschmeyer, Stephan Peitz, Jörg Schallenberg

Patent number: 10189755Abstract: The disclosure describes the oligomerization of supercritical ethene. An essential aspect of the invention is that of mixing ethene with an inert medium and setting the conditions in the reaction such that both ethene and the inert medium are supercritical. This is because the solubility for ethene in the inert medium is greater in the supercritical state, such that more ethene is dissolved in the supercritical inert medium than in a liquid solvent. The process regime in the supercritical state therefore enables the use of a much higher proportion of ethene in a homogeneous mixture of ethene and inert medium than is possible on the basis of the thermodynamic solubility restriction in a purely liquid hydrocarbon stream. In this way, the space-time yield is distinctly enhanced. Since a greater amount of ethene can be passed into the reactor, it is possible as a result to better exploit the apparatus volume compared to a liquid phase process. The inert medium used may, for example, be isobutane.Type: GrantFiled: May 25, 2017Date of Patent: January 29, 2019Assignee: Evonik Degussa GmbHInventors: Helene Reeker, Guido Stochniol, Dietrich Maschmeyer, Stephan Peitz, Jörg Schallenberg

Publication number: 20180208538Abstract: The invention relates to a process for preparing an ester mixture, in which an n-butene-containing feed mixture having a composition which changes over time is first oligomerized and then converted by hydroformylation, hydrogenation and esterification to an ester mixture. In this process, an approximation of the actual viscosity of the ester mixture is determined. The problem that it addresses is that of specifying a comparatively simple process which enables conversion of an n-butene with a variable composition over time to an ester mixture having a viscosity which can be kept very substantially constant over a long period even when an inconstant C4 source which delivers fluctuating qualities over this period is utilized. This is achieved through controlled use of a second raw material, namely ethene. It has been found that the viscosity of n-butene-based ester mixtures can be influenced by controlled use of ethene in the preparation of the ester precursors.Type: ApplicationFiled: March 19, 2018Publication date: July 26, 2018Inventors: Helene Reeker, Guido Stochniol, Dietrich Maschmeyer, Horst-Werner Zanthoff, Jörg Schallenberg, Frank Geilen, Katrin Marie Dyballa, Dirk Fridag, Stephan Peitz, Lena Altmann, Robert Franke

Publication number: 20180057473Abstract: The method for the epoxidation of propene comprises continuously reacting propene with hydrogen peroxide in the presence of a homogeneous epoxidation catalyst in a reaction mixture comprising an aqueous liquid phase and an organic liquid phase using a loop reactor with mixing of the liquid phases, withdrawing aqueous phase from the loop reactor and extracting it by liquid-liquid-extraction using propene as extractant to provide an extract comprising propene and propene oxide.Type: ApplicationFiled: February 3, 2016Publication date: March 1, 2018Applicant: Evonik Degussa GmbHInventors: Juergen Stock, Daniel REIN, Jörg SCHALLENBERG, Georg Friedrich THIELE
