VerfahrenzurDarstellungvonZinntetrachloridausZinndioxyd.
Es hat sich gezeigt, dass Zinndioxyd in glatter Weise in Zinntetrachlorid übergeführt werden kann, wenn es mit Kalziumkarbid innig gemischt, bei höherer Temperatur der Einwirkung von trockenem Chlorgas ausgesetzt wird. Die Reaktion vollzieht sich bei ver. hiiltnismässig niedriger Temperatur, 170 bis 2000, und scheint es hiebei zur Bildung eines 811 C. Ca C-Doppelsalzes zu kommen, aus welchem das Sn C l4 entweder durch Destillation oder auf dem Wege einer chemischen Umsetzung abgeschieden werden kann. Die Bildung des Zinntetrachlorid erfolgt quantitativ.
Zur Ausführung des Verfahrens wird Zinndioxyd, z. B. Zinnpaste aus den Seiden- färbereien oder das natürlich vorkommende Sn O2 (Kassiterit), in trockenem Zustande mit
EMI1.1
bei einer Temperatur von zirka 2000 der Einwirkung eines darüber streichenden trockenen Chlorstromes bis zur vollkommenen Sättigung mit Chlorgas ausgesetzt. Aus dem erhaltenen Reaktionsgemisch kann das Sn Cl4 auf folgende Weise abgeschieden werden :
1. Durch direktes Abdestillieren beim weiteren Erhitzen des Reaktionsgemisches.
Eventuell kann dabei die Abscheidung des S} durch die umsetzende Wirkung eines Zusatzes von primären oder sekundären Sulfaten erleichtert werden ;
2. durch Destillation über konzentrierte Schwefelsäure ;
3. durch Umsetzung des in dem Reaktionsgemisch vermutlich enthaltenen Sn Cl,. Col2- Doppelsalzes zu dem technisch verwertbaren Sn Cl4.2 NH4Cl (Pinksalz).

Process for the preparation of tin tetrachloride from tin dioxide.
It has been shown that tin dioxide can be converted smoothly to tin tetrachloride when it is intimately mixed with calcium carbide, exposed to the action of dry chlorine gas at a higher temperature. The reaction takes place at a relatively low temperature, 170 to 2000, and appears to result in the formation of a 811 C. Ca C double salt, from which the Sn C 14 is separated either by distillation or by chemical conversion can. The tin tetrachloride is formed quantitatively.
To carry out the process, tin dioxide, e.g. B. tin paste from the silk dye works or the naturally occurring Sn O2 (cassiterite), in a dry state with
EMI1.1
exposed at a temperature of about 2000 to the action of a dry chlorine stream sweeping over it until it is completely saturated with chlorine gas. The Sn Cl4 can be deposited from the reaction mixture obtained in the following way:
1. By direct distillation as the reaction mixture continues to be heated.
The separation of the S} can possibly be facilitated by the converting effect of an addition of primary or secondary sulfates;
2. by distillation over concentrated sulfuric acid;
3. by reacting the Sn Cl, presumably contained in the reaction mixture. Col2 double salt to the technically usable Sn Cl4.2 NH4Cl (pink salt).
