| titleOfInvention | METHOD FOR THE CONTINUOUS ELECTROCHEMICAL PREPARATION OF GOOD FILTRATABLE, PURE MG (OH) LOW 2, CHLORINE AND HYDROGEN FROM MGCL DEEP 2-POSSIBLE SOLUTIONS |
| abstract | The invention relates to a process for the continuous electrochemical production of readily filterable, pure Mg (OH) 2; Chlorine and hydrogen from MgCl2-containing solutions. The Mg (OH) 2 thus produced is easy to filter and, after a washing process, is very pure and can be used as a filler. It can also be worked up by known Calcinations- or sintering process to high quality MgO-Kaustern or -Sintern. The resulting chlorine has the purity known from chloralkali electrolysis. The invention is based on the technical problem of developing a very simple and economically favorable process for the preparation of Mg (OH) 2, which makes it possible to produce a readily filterable Mg (OH) 2 in an electrolytic cell to be operated continuously remove the cell and where no encrustation of the cathode occurs. According to the invention, the technical object is achieved by electrolysis being carried out in a diaphragm cell with separate anolyte and catholyte pass, so that an almost saturated alkali chloride solution is fed to the anode compartment and an Mg 2 -ionic solution, in particular a Mg 2+ ion solution, is added to the cathode compartment. containing alkali metal chloride solution, which contains carbonate ions in the form of soluble salts with contents 1.5 g CO32 / l, that a ratio of the current intensity to the cathode volume of 18 kA / m3 must not be exceeded and that the electrolysis conditions are adjusted so that z a Truebedichte of 20-150 g Mg (OH) 2 / l sets, wherein the MgCl2 content of the supplied solution can be depleted to any value {magnesium hydroxide; Chlorine; Hydrogen; Electrolysis; diaphragm cell; MgCl2-containing solutions; separate anolyte and catholyte run} |
