Patent number: 12180141Abstract: A process produces sodium and/or potassium alkoxides in countercurrent by reactive rectification. Alcohol is reacted in countercurrent with the respective alkali metal hydroxide. The vapours containing alcohol and water are separated in at least two serially arranged rectification columns. The energy of the vapour obtained in the second rectification is utilized for operating the first rectification. This specific energy integration coupled with establishing a certain pressure difference in the two rectification stages makes it possible to cover a particularly large proportion of the energy required for the rectification through heating steam and minimizes the use of electricity.Type: GrantFiled: April 13, 2022Date of Patent: December 31, 2024Assignee: Evonik Operations GmbHInventors: Dirk Roettger, Sebastian Reimann, Niklas Paul, Armin Matthias Rix, Moritz Schröder, Philip Zitzewitz

Publication number: 20240279145Abstract: The present invention relates to a process for workup of a methanol/water mixture which is employed in the production of alkali metal methoxides in a reaction column. The mixture is distillatively separated in a rectification column. The vapours obtained at the upper end of the rectification column are compressed in at least two stages and the energy of the vapours compressed in each case is advantageously transferred to bottoms and side streams of the rectification column. This allows particularly energy-efficient use of the energy of the compressed vapours in the process according to the invention. The process for workup of a methanol/water mixture is employed in the production of alkali metal methoxides in a reaction column, wherein methanol and alkali metal hydroxide solution are reacted with one another in countercurrent in a reaction column.Type: ApplicationFiled: March 23, 2022Publication date: August 22, 2024Applicant: EVONIK OPERATIONS GMBHInventors: Dirk ROETTGER, Moritz SCHRÖDER, Niklas PAUL, Armin Matthias RIX, Philip ZITZEWITZ, Martin OLDEMEYER, Martin WÜLLER, Tanita Valèrie SIX, Johannes RUWWE

Patent number: 11964940Abstract: A method for separating butenes from C4 hydrocarbon streams containing butanes and butenes involves extractive distillation with a suitable solvent, and a subsequent adiabatic oligomerisation. The method also involves heat integration, which makes it possible to use the heat of the solvent in order to heat and/or at least partly evaporate various streams.Type: GrantFiled: January 21, 2022Date of Patent: April 23, 2024Assignee: Evonik Oxeno GmbH & Co. KGInventors: Philip Lutze, Stephan Peitz, Armin Matthias Rix, Tanita Valèrie Six, Moritz Schröder, Niklas Paul

Patent number: 11746075Abstract: A process can be used for preparing sodium and potassium alkoxides. The process is characterized by two simultaneously implemented but spatially separated reactions of an alcohol ROH with NaOH, and ROH with KOH, to give sodium alkoxide and potassium alkoxide, respectively. The vapours formed in this case contain the alcohol used and water. The vapours are combined, and the resulting mixed vapour is fed to a common distillation with recovery of the alcohol.Type: GrantFiled: November 30, 2020Date of Patent: September 5, 2023Assignee: Evonik Functional Solutions GmbHInventors: Dirk Roettger, Sebastian Reimann, Manfred Neumann, Moritz Schröder, Philip Zitzewitz, Niklas Paul, Armin Matthias Rix

Patent number: 11634372Abstract: A method can be used for producing alkali metal alcoholates in counter flow by reactive rectification. The alkali metal is selected from sodium and potassium. In a first part of the method, the alcohol is converted in counter flow with the respective alkali metal hydroxide. In a second part of the method, the mixture of alcohol and water obtained is separated in a rectification column, and the alcoholic vapour arising is condensed, as a result of which the temperature thereof increases. The energy dissipated during cooling of the condensed vapour is then used in the first part of the method. This permits an energy-efficient production of the alkali metal alcoholates concerned.Type: GrantFiled: November 30, 2020Date of Patent: April 25, 2023Assignee: Evonik Functional Solutions GmbHInventors: Dirk Roettger, Sebastian Reimann, Manfred Neumann, Moritz Schröder, Philip Zitzewitz, Niklas Paul, Armin Matthias Rix
