Description

Verfahren zur Herstellung von organischen Schwefelverbindungen. Es wurde gefunden, daß den durch Einwirkung von Acetylen auf Kupfer oder dessen Verbindungen erhaltenen Polymerisations-bzw. Kondensationsprodukten des Acetylens, die unter dem Namen Cupren bekannt sind, Schwefel angelagert oder einverleibt werden kann, wenn man die Kondensationsprodukte mit Schwefel oder Sulfiden der Metalloide, z. B. Chlorschwefel, behandelt. Die Behandlung geschieht bei erhöhter Temperatur unter 300° und kann vorteilhaft unter Druck vorgenommen werden. Die erhaltenen Produkte können in der Kautschukindustr ie verwendet werden. Beispiele: i. 5 kg Cupren wurden mit Benzol zu einem dünnen Brei angerührt und zu dieser Aufschlämmung 5 kg Chlorschwefel zugesetzt. Nach zweistündigem Erwärmen am Rückflußkühler wurde filtriert und der Rückstand mit Schwefelkohlenstoff bis zur Erschöpfung extrahiert. Die Analyse des Produktes ergab einen Schwefelgehalt von i i,o Prozent.Process for the production of organic sulfur compounds. It it was found that the action of acetylene on copper or its compounds obtained polymerization or. Condensation products of acetylene, which under are known by the name cuprene, sulfur can be deposited or incorporated, if the condensation products with sulfur or sulfides of the metalloids, eg. B. chlorosulfur treated. The treatment takes place at an elevated temperature below 300 ° and can advantageously be carried out under pressure. The products received can be used in the rubber industry. Examples: i. 5 kg of cups were made mixed with benzene to a thin paste and added to this slurry 5 kg of chlorosulfur added. After two hours of refluxing, the mixture was filtered and the Residue extracted with carbon disulfide until exhaustion. The analysis of the Product gave a sulfur content of i i, o percent.

2. 5 kg Cupren, mit Benzol zu einem Brei angerührt, wurden -wieder mit 5 kg Schwefelchlorür, entsprechend 2,37 kg Schwefel, zwei Stunden lang im Autoklav auf i8o bis 2oo° (io Atm.) erwärmt, filtriert und mit Schwefelkohlenstoff erschöpfend extrahiert. Der Filterrückstand wog getrocknet 6,05 kg, hatte also um 21 Prozent zugenommen. Die Analyse ergab 13,6 Prozent Schwefel und .4 Prozent Chlor.2. 5 kg of cuprene, mixed with benzene to a pulp, were again heated with 5 kg of sulfuric chloride, corresponding to 2.37 kg of sulfur, for two hours in an autoclave to 180 to 200 ° (10 atm.), Filtered and exhausted with carbon disulfide extracted. The dry filter residue weighed 6.05 kg, which means that it had increased by 21 percent. Analysis found 13.6 percent sulfur and .4 percent chlorine.

3. 51g Cupren, mit Benzol angeschlämmt, und 5 kg Schwefel wurden zusammen im Autoklav zwei Stundenlang auf iSo bis igo° erhitzt. Die Masse wurde hierauf abgepreßt, mit Schwefelkohlenstoff extrahiert und getrocknet. Sie enthielt 6,8 Prozent Schwefel.3. 51 g of cupren, slurried with benzene, and 5 kg of sulfur were put together heated in the autoclave to iSo to igo ° for two hours. The mass was then squeezed out extracted with carbon disulfide and dried. It contained 6.8 percent sulfur.
