Abstract

The invention relates to a process for producing at least one alkali metal methoxide by reactive distillation in at least one reaction column. At the lower end of the reaction column(s), the respective alkali metal methoxide dissolved in methanol is withdrawn. The methanol/water mixture obtained at the top of the reaction column(s) is separated by distillation in a rectification column. The vapors obtained at the upper end of the rectification column are compressed in at least two stages, and the energy of the vapors compressed in each case is advantageously transferred to bottoms and side streams of the rectification column. This allows a particularly efficient use of the energy of the compressed vapors in the process according to the invention. Additionally, the energy of the alkali metal methoxide product stream obtained at the lower end of the reaction column(s) is advantageously transferred to the vapor streams from the rectification column, in particular before said vapors are subjected to a compression process. The energy from the compressed vapors can additionally be used to operate the reaction column(s) or a reaction column in which a process for transalcoholization of alkali metal alkoxides is conducted.

The present invention relates to processes for producing cut metal bodies, comprising the providing of metal bodies, the subsequent applying of metal-containing powders, a thermal treatment for alloy formation and the splitting of the alloyed metal bodies using a process selected from the group: severing, machining with geometrically defined cutting edge and waterjet cutting. The temperature profile in the thermal treatment allows alloy formation to take place at the contact surface between metal body and metal-containing powder, but at the same time leaving unalloyed regions in the interior of the metal body. The present invention further relates to processes in which the splitting of the alloyed metal bodies is followed by a treatment with leaching agent so as to obtain catalytically active metal bodies. The use of the inventive splitting process for producing the cut metal bodies affords particularly active catalysts. The present invention further relates to the use of the catalysts obtained by the processes of the invention in chemical transformations.

Abstract

The present invention relates to a process for producing at least one alkali metal methoxide by reactive distillation in at least one reaction column. At the lower end of the reaction column(s), the respective alkali metal methoxide dissolved in methanol is withdrawn. The methanol/water mixture obtained at the top of the reaction column(s) is separated by distillation in a rectification column. The energy from the vapour obtained at the top of the rectification column is transferred to a liquid or gaseous heat transfer medium, and the gaseous heat transfer medium obtained as a result is compressed in at least two stages. The energy from the respectively compressed heat transfer medium is advantageously transferred to the bottom stream and sidestream from the rectification column. This enables particularly energy-efficient use of the energy from the vapour in the process of the invention. The energy from the compressed heat transfer medium may additionally be used for operation of the reaction column(s) or for operation of a reaction column in which a process for transalcoholization of alkali metal alkoxides is conducted.

The invention relates to catalytically active heating elements, and to the production and use thereof in the production of hydrogen cyanide (HCN). The problem addressed by the invention is that of providing thermally stable and catalytically active heating elements with which a BMA process can be simultaneously electrically heated and chemically catalysed. In particular, the heating elements should be thermally and mechanically stable in continuous industrial operation and retain their catalytic activity. The heating element according to the invention has a layered structure (A, B, C) formed from (A) silicon carbide (SiC), (B) aluminium nitride (AlN) and (C) platinum (Pt). The silicon carbide (SiC) serves as an electric heating resistor. The platinum (Pt) serves as catalyst. Aluminium nitride (AlN) is arranged as a protective layer between platinum (Pt) and silicon carbide (SiC). It prevents platinum (Pt) and silicon carbide (SiC) from alloying during ongoing operation.

Abstract

A process for the epoxidation of propene involves reacting propene with hydrogen peroxide, in the presence of a methanol solvent and a shaped titanium zeolite epoxidation catalyst in a fixed bed reactor. The process then involves recovering methanol from the reaction mixture, treatment of the recovered methanol by passing it through a bed of an acidic ion exchange resin, and recycling the treated methanol to the epoxidation reaction; as well as regeneration of the acidic ion exchange resin. Catalyst breakage can be reduced or avoided by washing the regenerated bed of an acidic ion exchange resin with methanol until the methanol exiting the resin bed has an apparent pH higher than 1.8, before methanol treated with the acidic ion exchange resin is recycled to the epoxidation reaction.

Abstract

The present invention relates to the electrochemical production of hydrogen and lithium hydroxide from Li+-containing water using a LiSICon membrane. The problem addressed by the present invention is that of specifying a process which is operable economically even on an industrial scale. The process shall especially exhibit a high energy efficiency and achieve a long service life of the membrane even when the employed feed contains impurities harmful to LiSICon materials. A particular aspect of the process is that the cell simultaneously separates off the lithium via the membrane and effects electrolysis of water. An essential aspect of the process is that the electrochemical process is performed in a basic environment, more precisely at pH 9 to 13. The pH is adjusted by addition of a basic compound to the feed.

Abstract

Present invention relates to an apparatus (0) for producing nanocarriers and/or nanoformulation and a process for producing a nanocarrier and/or a nanoformulation by means of this apparatus (0). According to inventive preparation, a first liquid phase (A) and the second liquid phase (B) are mixed first to give the primary mixture (A+B) by means of a static mixer (4). In a subsequence mixing step primary mixture (A+B) is diluted with a third liquid (C). An important aspect of apparatus (0) is the arrangement of the static mixer (4) inside a linear pipe (7) conducting third liquid phase (C). Thus, the primary mixture (A+B) exiting the mixer (4) is instantaneously diluted with (C) to give secondary mixture (A+B+C). The volume flow of the third mixture (C) is chosen larger than the volume flow of the primary mixture (A+B). By these measures, nanocarriers with improved morphology and homogeneity are produced. Encapsulation efficiency was enhanced as well.
