Abstract

The present invention relates to a process for preparing metal alcoholate compounds MOR2from the metal hydroxides MOH and the compounds of formulae R1OH and R2OH, wherein the boiling point of R1OH is lower than that of R2OH. R1and R2are alkyl functional groups or haloalkyl functional groups, the carbon chain of which can be interrupted by ether groups, and which can comprise hydroxy groups. M is a metal, preferably an alkali metal. By contrast with the conventional processes for realcoholisation which require at least two reaction steps in two different reactive distillation columns, the process is performed in the form of multiple reactive distillation in one reactive distillation column. This results in a reduction in the complexity of the apparatus and a reduction in the need for power and heating steam. The process is suitable in particular for preparing compounds MOR2in which the corresponding compound R2OH forms an azeotrope with water, and/or in which the boiling point of R2OH is close to the boiling point of the water.

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 At the lower end of the reaction column(s), the respective alkali metal methoxide dissolved in methanol is withdrawn.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.

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 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.
