At the same time, the mechanical stability of the arrangement of the at least two solid-state electrolyte ceramics between the parts R1 and R2 is increased in that the parts R1 and R2 are secured to one another both at the edge element RR and at the separating element RT by at least one securing element BR or BT.

The invention relates to the electrodialytic production of ammonia and sulfuric acid from ammonium-sulfate-rich (waste) waters. An object of said invention was to provide a process for recovering ammonia and sulfuric acid from waters containing ammonium sulfate in high concentrations.

APPARATUS FOR THE PRODUCTION OF NITRILES AND USE THEREOF
It is an object of the invention to specify an electrically heatable reactor for hydrogen cyanide production and the production of other nitriles, which enables a differentiated temperature profile and works with inexpensive standard components. The core of the inventive apparatus (0) is a chamber (1) made from gas-permeable, thermally insulating material that constitutes the actual reaction space. Electrical heating elements (5) project into the chamber (1), such that the chamber (1) can be heated from the inside by heating elements (5). The electrical terminals of the heating elements are outside the reaction space but within the surrounding shell. Unlike in the case of the industrially implemented BMA process, the heat is thus not transported into the reaction space from the outside but generated in the reaction space. Heat is generated by conversion of electrical energy by means of the heating elements (5) by the principle of resistance heating. In order to ensure gastightness of the apparatus (0), a shell (9) is provided, which surrounds the chamber (1) in a gastight manner.

The invention relates to the coating of anion exchange membranes with catalytically active substances. The catalytically actively coated anion exchange membranes are used in electrochemical cells, especially for water electrolysis. The problem addressed by the invention is that of specifying a process for coating an anion exchange membrane which can be conducted at relatively low temperatures. This problem is solved by a swelling step. Aside from the swelling step and the processing temperature, the sequence of the process according to the invention resembles a decal process.

The advantage of the process according to the invention is that it can be conducted at comparatively low temperatures, namely below 100°C.
