Description
Verfahren zum Stabilisieren von Chlorierungsprodukten von höhermolekularen Kohlenwasserstoffen Die Erfindung betrifft ein Verfahren zur Stabilisierung von Chlorierungsprodukten höhermolekularer Kohlen-,vasserstoffe. Es besteht darin, daß dem Chlorierungsprodukt Stabilisatoren, wie die Aminogruppe - \T H., enthaltende Stoffe, insbesondere Harnstoff in kleinen Mengen zugegeben werden und hierauf bei Temperaturen unterhalb ioo° ein Durchleiten von Luft oder iiierten Gasen bis zur Entfernung des entstandenen Chlorwasserstoffs und des nicht gebundenen Chlors vorgenommen wird.Process for stabilizing chlorination products of higher molecular weight Hydrocarbons The invention relates to a method for stabilizing Chlorination products of higher molecular weight carbons, hydrogen. It is that the chlorination product containing stabilizers, such as the amino group - \ T H. Substances, especially urea, are added in small amounts and on this Temperatures below 100 ° a passage of air or iiierten gases up to Removal of the resulting hydrogen chloride and the unbound chlorine carried out will.
Es ist bekannt, daß Chlorierungsprodukte von Kohlenwasserstoffen sich leicht zersetzen. Zu diesein Zweck sind schon Stoffe, wie Schwefel, Amine, Äthylenimine, Amide, Imide von Carbonsäuren und andere basische Stickstoffverbindungen, Terpene u. dgl., zum Stabilisieren verwendet worden. Ein durchschlagender Erfolg ist dadurch aber noch nicht erreicht worden. Es wurde nun erkannt, daß die Verwendung von Stabilisatoren dann zum restlosen Erfolg führt, wenn nach deren Zugabe eine gute Austreibung des entstandenen Chlorwasserstoffs und des nicht gebundenen Chlors stattfindet. Als Austreibungsgas verwendet man zweckmäßigerweise Luft, jedoch sind auch andere Gase, wie Stickstoff, Kohlensäure u. dgl., möglich. Es ist wichtig, daß hierbei die Temperatur unterhalb 10o° liegt, um eine schonende Behandlung zu gewährleisten. Vorteilhafterweise wird die Luft nicht durch das Chlorierungsprodukt hindurchgedrückt, sondern gesaugt, da dadurch eine bessere und gleichmäßigere Verteilung der Luft herbeigeführt wird. Die gute Verteilung wird im übrigen durch Anwendung besonderer Verteiler, wie Siebplatten, Filterkerzen, Fritten u. dgl., bewirkt. Als Stabilisator ist besonders Harnstoff geeignet, aber auch andere die Aminogruppe - N H, enthaltende Stoffe, wie Thioharnstoff, Anilin us"v., sind verwendbar.It is known that chlorination products of hydrocarbons are decompose easily. For this purpose substances such as sulfur, amines, ethylene imines, Amides, imides of carboxylic acids and other basic nitrogen compounds, terpenes and the like, have been used for stabilization. This is a resounding success but has not yet been achieved. It has now been recognized that the use of stabilizers then leads to complete success if, after adding them, a good expulsion of the resulting hydrogen chloride and the unbound chlorine takes place. as The expulsion gas is expediently air, but other gases are also such as nitrogen, carbonic acid, etc., possible. It is important that the temperature here is below 10o ° in order to ensure gentle treatment. The air is advantageously not forced through the chlorination product, but sucked, as this results in a better and more even distribution of the air is brought about. The good distribution is also made special by the application Distributors, such as sieve plates, filter candles, frits and the like. As a stabilizer Urea is particularly suitable, but also others containing the amino group - N H Substances such as thiourea, aniline, etc. can be used.
Das Verfahren wird mit besonderem Erfolg bei solchen Chlorierungsprodukten angewendet, die als Zusätze bei anderen Materialien dienen und wo bereits eine geringe Zersetzung untragbar sein würde. Ein solcher Verwendungszweck ist z. B. die Verwendung als Weichmacher für Kunststoffe, insbesondere synthetischer Kautschuk.The process has found particular success with such chlorination products used, which serve as additives in other materials and where already a small one Decomposition would be intolerable. Such a use is e.g. B. the use as a plasticizer for plastics, especially synthetic rubber.
Ausführungsbeispiel In ein Chlorierungsprodukt aus einem Paraffin mit Schmelzpunkt von 520- und einem Cl-Gehalt von 16 °/o wird o, i ofa Harnstoff zugegeben und dann mittels eines Strahlenapparats etwa 2o Stunden Luft durch die auf etwa 7ö° erhitzte Masse gesaugt, bis kein Chlorwasserstoff und freies Chlor mehr nachweisbar sind. Das Produkt ist dann völlig. stabil und kann ohne Zersetzungsgefahr für die verschiedenen Zwecke verwendet «erden.Embodiment In a chlorination product of a paraffin with a melting point of 520- and a Cl content of 1 6 ° / o o, i ofa urea was added, and then sucked through the heated to about 7ö ° mass by means of a radiation apparatus about 2o hours air until no more hydrogen chloride and free chlorine can be detected. The product is then complete. stable and can be used for various purposes without the risk of decomposition.
