Najdluzszy czas trwania patentu do dnia 5 grudnia 1942 r.Przedmiot patentuj 8107 stanowi sposób znamienny tern, ze materjaly zawierajace magnezje, zarobione stopionjym chlorkiem magniez,u lub stopiionemi solami zawiietraja- oemi chlorek m^gneziu, przesacza sie przez ogrzewana wieze, przez która przeplywa w odwrotnym kiejraniku, to znaczy z-dolu do góry, gazowy czynnik reakcyjny isluzacy da wytwarzania chlorków.Sposób powyzszy mozna bardzo ko¬ rzystnie polaczyc z inna znana metoda, w mysl której z tlenowych zwiazków, sluza¬ cych jako materjal surowy (np. magnezja), wyrabia sie ksztaltki zawierajace domiesz¬ ke materjialów wytwarzajacych pory w cza- isie ogrzewania, co zabezpiecza staly .dostep chloru (do ich wnetrza.Silnie porowate i skoksowane ksztaltki uklada sie w mysl niniejszego wynalazku w odpowiednim zbiorniku, np. wedlug pa¬ tentu 8107 na elektrycznie ogrzewanej war¬ stwie filtracyjnej umieszczonej w wiezy, poczerni wpuszcza sie do wiezy zdolu chlor, który przeplywa potem przez cala war¬ stwe filtracyjna. Reakcja jest silnie eigjzo- termiczna wskutek czego temperatura przerabianego materjalu wzrasta, a tern samem reakcja sie przyspiesza. Tempera-tura wzrasta ponad punkt topliwosci chlor¬ ku magnezu, $ak ze ^otazymiuje sie plynny chlorek ipagnezif m^wierajacy tylko niewiel¬ ki procent magnezji A nileco wegla (ewen¬ tualnie obok inmych chlorków). Stopiony chlorek magnezu pochlania zaraz nizej le¬ zaca warstwa filtracyjna, ogrzana do oko¬ lo 800°, przyczem chlorek magnezu, prze¬ plywajac przez te warstwe, styka sie na wielkiej powierzchni z plynacym wigore, silnie stezonym chlorelm, który resztki magnezji zamienia jesizcze na chlorek ma¬ gnezu, tak ze ostatecznie otrzymuje sie (w jedlnym zabiegu roboczym) z magnezji, lub materjalów tworzacych MgO, bardzo czy¬ sty, stopiony chlorek magnezu, niezawiera- jacy wodly.Przy przeróbce ksztaltek w celu prze¬ miany tlenków na chlorki sposobem poda¬ nym na wstepie trzebaby bylo utrzymywac temperature reakcja (chlorowania) ponizej temperatury topliwosci wytwarzanego chlorku, natomiast, przeprowadlzajac pro¬ ces w mysl niniejszego wynalazku, korzy¬ sta sie z moznosci podwyze,zenia tempera¬ tury w celu przyspieszenia procesu chloro¬ wania, bo ogrzana warstwa filtracyjna u- mozliwia natychmiastowy odplyw topiace¬ go sie chlorku, zanim ten ostatni moze sie zetknac i zmieszac z materjalem zawieraja¬ cym wiele tlenków, wytwarzajac mase nie¬ zdolna (do reakcji. Chlor niezuzyty w glów¬ nej strefie reakcyjnej pochlaniaja calkowi¬ cie ksztaltki lezace wyzej, ogjrzane przez gazy wylotowe.Opisany sposób moze sluzyc równiez do wytwarzania innych bezwodnych chlor¬ ków, nileulatniajajcych sie przy temperatu¬ rze ich powstawania. Taknp. mozna otrzy¬ mac z odpowiednich tlenków chlorki CaCl2 ZnCl2 i inne. PLThe longest term of the patent until December 5, 1942 The subject of patent 8107 is a method characterized by the fact that materials containing magnesia, made with molten magnesium chloride, or with molten salts of magnesium chloride, passes through a heated tower through which it flows in the reverse tap, i.e. downwards, the gaseous reaction agent and the aid for the production of chlorides. The above method can very advantageously be combined with another known method in which the oxygen compounds serving as the raw material (e.g. ), shapes are made containing an admixture of pore-forming materials during heating, which ensures a constant access of chlorine (to their interior. Highly porous and coked shapes are arranged in accordance with the present invention in a suitable tank, e.g. according to the pellet) 8107 on the electrically heated filter layer placed in the tower, the blackened filter is blown into the tower with chlorine, which then flows through complete filter layer. The reaction is highly exothermic, as a result of which the temperature of the processed material increases, and the reaction itself accelerates. The temperature rises above the melting point of magnesium chloride, as liquid chloride and magnesium is obtained, containing only a small percentage of non-carbon magnesium (possibly in addition to other chlorides). The molten magnesium chloride absorbs just below the lying filter layer, heated to about 800 °, while the magnesium chloride, flowing through this layer, contacts on a large surface with the flowing vigor, strongly concentrated chlorelm, which transforms the remains of magnesia into ashes. magnesium chloride, so that ultimately (in one operation) is obtained from magnesia or materials that form MgO, a very pure, molten magnesium chloride, free from water. When working the particles to convert the oxides to chlorides by the method given in the introduction, it would be necessary to keep the temperature of the (chlorination) reaction below the melting point of the chloride produced, whereas, in the course of the present invention, it is possible to increase the temperature in order to accelerate the chlorination process. because the heated filter layer allows the molten chloride to drain away immediately, before the latter can come into contact and mix with the material containing absorbing many oxides, producing a mass incapable of reacting. Chlorine not consumed in the main reaction zone completely absorbs the above-lying shapes, heated by the exhaust gases. The method described can also be used to produce other anhydrous chlorides which are neviating at the temperature of their formation. Yes e.g. CaCl2, ZnCl2, and others can be obtained from the corresponding oxides. PL
