Description

Verfahren zur Herstellung von Allylsenfölen Es ist bekannt, daß man bei der Umsetzung von gesättigten Alkyljodiden und -bromiden mit rhodanwasserstoffsauren Salzen die entsprechenden Rhodanwasserstoffsäureester erhält, während sich durch ' Umsetzung von Allylbromid mit Kaliumrhodanid in alkoholischer Lösung oder durch Behandeln von Allyljodid mit haliumrhodanid in Gegenwart von etwas Wasser das Allylsenföl herstellen liil5t. Allylchloride hat maii bisher mit rhodanwasserstoffsauren Salzen nicht umgesetzt.Process for the preparation of allyl mustard oils It is known that one in the reaction of saturated alkyl iodides and bromides with rhodanic acids Salts the corresponding hydrothodanic acid ester is obtained while by itself '' Reaction of allyl bromide with potassium rhodanide in alcoholic solution or by Treating allyl iodide with halium rhodanide in the presence of some water the allyl mustard oil manufacture liil5t. Allyl chlorides have so far been used with rhodanic acid salts Not translated.

Es wurde nun gefunden, daß man in sehr einfacher Weise Allvlsenföle erhält., wenn man Gentische »aus Allylchlorid oder Chlorallylclilorid und gesättigten Chlorkohlemvasserstotten mit löslichen Salzen der Rhodanwasserstoffsäure in Gegenwart von einer Menge Wasser umsetzt, die zur Lösung dieser Salze ausreicht. Die Umsetzungsfähigkeit des Allylchlorids und Chlorallylchlorids mit rhodanwasserstoffsauren Salzen ist im Vergleich zu der gesättigter Clilorkohlenwasserstoffe so groß, daß aus den Mischungen von Allylchlorid .oder Chlorallylchlorid mit gesättigten Chlorkohlenwasserstoiten, wie man sie beispielsweise bei der Herstellung von Allylchlorid oder Chlorallylchlorid gelegentlich erhält, nur das Allylsenföl gebildet wird, während man die gesättigten Chlorkohlenwasserstotte unverändert abtrennen kann.It has now been found that universal mustard oils can be obtained in a very simple manner obtained if one uses genetics from allyl chloride or chloroallyl chloride and saturated Chlorocarbon water stetting with soluble salts of hydrofluoric acid in the presence of an amount of water that is sufficient to dissolve these salts. The ability to implement of allyl chloride and chloroallyl chloride with salts of rhodanic acid Compared to the saturated chlorohydrocarbons so large that from the mixtures of allyl chloride. or chlorallyl chloride with saturated chlorinated hydrocarbons, as they are used, for example, in the production of allyl chloride or chloroallyl chloride Occasionally, only the allyl mustard oil is formed, while one gets the saturated ones Can separate chlorinated hydrocarbons unchanged.

Man führt die Umsetzung im all;-emeinen in der Weise durch. daß inan die Ausgangsmischung mit wäßrigen Lösungen von rhodanwasserstoitsauren Salzen. insbesondere von Alkali- oder Erdalkalirhodaniden, erwärmt. Es ist auch möglich, in wäßrig-alkoholischcr Lösung zu arbeiten, jedoch ist dies meist nicht erforderlich. Im allgemeinen genügt es, die Umsetzungsmischung einige. Zeit lang am Rückflußkühler zu kochen. Man kann auch im geschlossenen Gefäß arbeiten, um die Umsetzungsdauer zu ver-ürzen. -Beispiel Zoo Teile eines aus 700!o I, 3-Dichlorpropen-2 und 300`o 1, 2-Dichlorpropan bestehenden Gemisches erhitzt man 3 Stunden lang am Rückflußkühler unter Rühren bei 75° mit einer Lösung von 13o Teilen Magnesiumrhodanid in 3oo Teilen Wasser. Man unterwirft dann das Umsetzungsgemisch einer Wasserdampfdestillation, wobei das gebildete y-Clilorpropenylsenföl zusammen mit dem völlig unveränderten I, 2-Dichlorpropan abdestilliert. Man entfernt aus dem Destillat den öligen Bestandteil, trocknet mit wasserfreiem Natriumsulfat und trennt dann durch Destillation das Senföl ab. Die Ausbeute beträgt etwa 750/'o der berechneten Menge.The implementation is generally carried out in this way. that inan the starting mixture with aqueous solutions of salts of rhodanhydric acid. in particular of alkali or alkaline earth rhodanides. It is also possible to use water-alcoholic cr Solution to work, however, this is mostly not necessary. in the in general, it is enough to mix up the implementation some. For a long time on the reflux condenser to cook. You can also work in a closed vessel in order to achieve the implementation time to shorten. -Example zoo parts one from 700! O I, 3-dichloropropene-2 and 300`o 1, 2-dichloropropane existing mixture is heated for 3 hours on the reflux condenser with stirring at 75 ° with a solution of 130 parts of magnesium rhodanide in 300 parts Water. The reaction mixture is then subjected to steam distillation, where the y-Clilorpropenyl mustard oil formed together with the completely unchanged I, 2-dichloropropane distilled off. The oily component is removed from the distillate, dries with anhydrous sodium sulfate and then separates the mustard oil by distillation away. The yield is about 750 per cent of the calculated amount.
