Description
Verfahren zur Herstellung von Additionsverbindungen aus Acetylen und Chlor. Das Hauptpatent betrifft ein Verfahren zur Verbindung von Acetylen und Chlor, das sich dadurch kennzeichnet, daß die Gase ohne Vorschaltung eines festen Verdünnungsmittels oder Anwendung einer Flüssigkeit durch einen aus kleinstücki.gem Metall bestehenden Katalysator geführt werden, wobei zunächst das Metall durch Chlor oberflächlich in Chlorid verwandelt werden kann. Es hat sich nun gezeigt, daß sich Metalloxyde, insbesondere Eisenoxyde, noch besser zu; Katalysatoren eignen. -Eisenverbindungen, namentlich Eisenoxyde, sind' an sich bekannte Ohlorierungskatalysatoren (vgl. die Patentschrift r74o68, Seite i, Zeile 49, und S a bi a t i e r , Dde Katalyse ;in der organischen Chemie 1914, Seite 32. Absatz 2 .und 6). Nach der Erfindung werden sie unter den Bedingungen des Hauptpatents, d. h. in kleinstöckiger Form und, ohne Vorsehaltungeines festem Verdünnungsmittels oder Anwendung einer Flüssigkeit an Stelle der Metalle, und zwar mit Vorteil benutzt.Process for the preparation of addition compounds from acetylene and Chlorine. The main patent relates to a process for combining acetylene and chlorine, which is characterized by the fact that the gases are used without an upstream solid diluent or application of a liquid through one made of small pieces of metal Catalyst are performed, whereby first the metal superficially by chlorine can be converted into chloride. It has now been shown that metal oxides especially iron oxides, even better too; Catalysts are suitable. -Iron connections, namely iron oxides are 'carbonation catalysts known per se (cf. Patent specification r74o68, page i, line 49, and S a bi a t i e r, Dde Catalysis; in of organic chemistry 1914, page 32. Paragraphs 2 and 6). According to the invention them under the terms of the main patent, d. H. in small-story form and without Provision of a solid diluent or application of a liquid Place of metals, and used with advantage.
Als geeignet hat sich eine ganze Reihe von Stoffen, .die im wesentlichen aus Eisenoxyd bestehen oder dieses in größeren Mengen; enthalten, wie gekörnte Kies.abbrände, eisenhaltiger Ton, Bauxit, erwiesen.A whole range of substances has proven to be suitable, essentially consist of iron oxide or this in larger quantities; contain, like granular gravel burns, ferruginous clay, bauxite, has been proven.
Beispiel i.Example i.
Ein Reaktionsturm wird mit vorher getrocknetern, eisenhaltigem Bauxit in Haselnuß- bis Erbsengröße gefühlt. Man führt von oben zunächst Chlor, bis die Luft verdrängt ist, und sodann Acetylen und Chlor im Verhältnis i : z Mol. ein. Die Reaktion wird durch gelindes Erwärmen eingeleitet und geht dann ununterbrochen ohne äußere Wärmezufuhr weiter. Man sorgt durch Kühlung dafür, daß die Temperatur nicht über i8o° steigt. Das unten austretende Gasgernisch wir' kondensiert und ein etwaiger Überschuß eines Reaktionsbestandteils in den Vorgang zurückgeführt. Die Ausbeute ist nahezu quantitativ. Kohleabsohedunbgen werden nicht beobachtet.A reaction tower is made with previously dried, ferrous bauxite felt in the size of hazelnuts to peas. Chlorine is first introduced from above until the Air is displaced, and then acetylene and chlorine in the ratio i: z mol. The reaction is initiated by gentle heating and then continues uninterrupted without external heat supply. It is ensured by cooling that the temperature does not rise above 180 °. The gas mixture emerging below is condensed and a any excess of a reaction component returned to the process. the The yield is almost quantitative. Carbon deposits are not observed.
Beispiel 2.Example 2.
Nach dem allgemeinen Verfahren .in Beispiel z werden an. Stelle von Bauxit Kiesabbrände verwandt, die vorher sorgfältig von ,den feinen Beimengungen, befreit werden. Die Ergebnisse sind die gleichen.Following the general procedure in Example z, an. Place of Bauxite gravel burns used, which were carefully removed from the fine additions, to be freed. The results are the same.
