Description
Verfahren zur Darstellung von Chloräthyl. In den Berichten der deutschen chemischen Gesellschaft, Bd. 6, S. 2,29, gibt M ü 11 e r an, daß das Äthylsch-uvefelsäurechlori.d (Chlorsulfonsäureäthylester) sich beim Erwärmen mit Wasser in Salzsäure, Schwefelsäure und Alkohol zersetzt, während B e h r e n d ; Journal für praktische Chemie (2), Bd. 15, S. 31, als Zersetzungsprodukte Ätherschwefelsäure und Salzsäure festgestellt hat.Process for the preparation of chloroethyl. In the reports of the German Chemical Society, Vol. 6, p. 2.29, M ü 11 he states that the Äthylsch-uvefelsäurechlori.d (chlorosulfonic acid ethyl ester) decomposes into hydrochloric acid, sulfuric acid and alcohol when heated with water, while B. honoring; Journal for practical chemistry (2), vol. 15, p. 31, has found ether sulfuric acid and hydrochloric acid as decomposition products.
Es wurde nun die bemerkenswerte Beobachtung gemacht, daB Äthylschwefelsäurechlorid (Chlorsulfonsäureäthylester), wie es z. B. aus dem Leucht- oder Kokereigas durch Behandeln mit Chlorsulfonsäure erhalten werden kann, durch Behandeln mit Salzsäure mit quantitativer Ausbeute in das wertvolle Chloräthyl und Schwefelsäure zerlegt wird.The remarkable observation has now been made that ethylsulphuric acid chloride (Ethyl chlorosulfonate), as it is, for. B. from the luminous or coke oven gas Treating with chlorosulfonic acid can be obtained by treating with hydrochloric acid decomposed into the valuable chloroethyl and sulfuric acid with quantitative yield will.
Die Reaktion verläuft schon bei gelindem Erwärmen des Esters mit gewöhnlicher konzentrierter Salzsäure. Sie kann in offenen oder geschlossenen Gefäßen ausgeführt werden.The reaction proceeds with a normal rate even when the ester is gently heated concentrated hydrochloric acid. It can be carried out in open or closed vessels will.
Beispiel i.Example i.
i Teil Chlorsulfonsäureäthylester wird in einem mit einem absteigenden Kühler versehenen Rührwerkskessel unter Rühren langsam mit 1,5 Teilen konzentrierter Salzsäure versetzt, die Temperatur wird innerhalb i bis 2 Stunden auf ioo° gebracht. Chloräthyl destilliert in gleichmäßigem Strome ab und wird durch den mit einer Kältemischung gefüllten Kühler kondensiert.i part of ethyl chlorosulfonate is in a descending order Stirring kettle provided with a cooler slowly with 1.5 parts of concentrated stirring Hydrochloric acid is added and the temperature is brought to 100 ° within 1 to 2 hours. Ethyl chloride distills off in a steady stream and is mixed with a cold mixture filled cooler condenses.
Beispiele. Es wird eine Mischung von i Teil Chlorsulfonsäureäthylester mit 1,5 Teilen rauchender Salzsäure im Autoklaven i Stunde lang auf ioo° erhitzt.Examples. A mixture of i part of ethyl chlorosulfonate is used heated to 100 ° for 1 hour in an autoclave with 1.5 parts of fuming hydrochloric acid.
Der Ester ist nach dieser Zeit verschwunden, das Chloräthyl scheidet sich beim Abkühlen oben auf dem wässerigen Salzschwefelsäüregemisch ab und kann, abgezogen werden.After this time the ester has disappeared and the chloroethyl separates when it cools down on top of the aqueous hydrochloric acid mixture and can, subtracted from.
Die Ausbeute an Chloräthyl entspricht annähernd der theoretischen.The yield of chloroethyl corresponds approximately to the theoretical one.
