Description

Verfahren zur Herstellung von Kondensationsprodukten Es ist bekannt, daß durch Umsetzung von Alkali-, Ammonium- oder Erdalkalipolysulfiden mit Polyhalogenderivaten von aliphatischen Kohlenwasserstoffen hachmolekuIare Kondensationsprodukte entstehen.Process for the production of condensation products It is known that by reacting alkali, ammonium or alkaline earth polysulfides with polyhalogen derivatives High molecular weight condensation products arise from aliphatic hydrocarbons.

Es wurde gefunden, daß man wertvolle Kondensationsprodukte erhält, wenn man Allylchlorid mit wässerigen Lösungen von Alkali-, Ammonium- oder Erdalkalipolysulfiden in der Wärme behandelt, bis kautschukartige plastische Massen entstanden sind. Die Massen sind vulkanisierbar. Sie können, gegebenenfalls nach Zugabe von Füllstoffen, auf Formkörper verarbeitet werden. Sie zeichnen sich durch Beständigkeit gegen Lösungsmittel und öle aus. Beispiel 7-o Gewichtsteile Natriumsulfid (hTa2S 9H20) werden mit 36o Gewichtsteilen Schwefel verschmolzen. Wenn der Schwefel gelöst ist, werden i8 o Gewichtsteile Wasser und i 8o Gewichtsteile :Methanol zugegeben. Unter ständigem Rühren und guter Rückflußkühlung werden nun 235 Gewichtsteile Allylchlorid langsam zugesetzt, und es wird noch i Stunde lang bei etwa 70° gerührt. Dann werden 2,5o Gewichtsteile eines Gemisches aus Methanol und Wasser abdestilliert. Das Destillat wird mit Kochsalz versetzt und dabei ausgeschiedenes Öl in das Reaktionsgefäß zurückgegeben. Nach Zugabe von 25o Gewichtsteilen Wasser wird das Reaktionsgemisch unter ständigem Rühren 5 Stunden lang auf 95' gehalten. Es bildet sich dabei eine zähe, braune Masse. Sie wird auf dar Walze ausgewaschen. Nach dem Trocknen erhält man 472 Gewichtsteile einer kautschukähnlichen - Masse, die gegen orga: nische Lösungsmittel und öle beständig ist und sich zur Herstellung von Formkörpern eignet.It has been found that valuable condensation products are obtained when using allyl chloride with aqueous solutions of alkali, ammonium or alkaline earth polysulphides treated in the heat until rubber-like plastic masses are formed. the Masses can be vulcanized. You can, if necessary after adding fillers, processed on molded bodies. They are characterized by resistance to solvents and oil out. Example 7-o parts by weight of sodium sulfide (hTa2S 9H20) are mixed with 36o Parts by weight of sulfur melted. When the sulfur is dissolved, i8 o Parts by weight of water and 18o parts by weight of methanol were added. Under constant Stirring and thorough reflux cooling are now 235 parts by weight of allyl chloride added, and it is stirred for another hour at about 70 °. Then 2.5o Parts by weight of a mixture of methanol and water are distilled off. The distillate table salt is added and the oil which has separated out is returned to the reaction vessel. After adding 250 parts by weight of water, the reaction mixture becomes under Maintained at 95 'for 5 hours with constant stirring. A tough, brown mass. It is washed out on the roller. After drying, one obtains 472 parts by weight of a rubber-like mass, which is against organic solvents and oils is resistant and is suitable for the production of moldings.
