Description
Verfahren zur Herstellung eines Harzes aus Nereaptothiazolidin-2-methyläther. Es wurde bereits vorgeschlagen, Xantho- genate der verschiedenen Alkohole mit Äthy- lenimin oder mit ChlorMhylamin zu Mer- captothiazolidinäthern umzusetzen.
Es wurde nun gefunden, dass diese Mer- captothiazolidinäther zu einer Reihe von Umsetzungen befähigt sind. Von technischer Bedeutung ist die Umsetzung der Mercapto- thiazolidinäther mit dem ringförmigen Äthy- lenimin.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines neuen Produktes, welches dadurch gekennzeichnet ist, dass man 2-Mercaptothiazolidin-2-methyl- äther und Äthylenimin zur Umsetzung bringt. Das so erhaltene Produkt soll als Zwischenprodukt, als Textilhilfsmittel oder Vulkanisationsbeschleuniger Verwendung fin den. An Stelle von Athylenimin können auch äquivalente Mengen Halogenäthylamin mit der dem Halogen entsprechenden Menge Lauge verwendet werden.
<I>Beispiele:</I> 1. 151 g 2-Mercaptothiazolidin-2-methyl- äther werden in 200 cm' Methanol gelöst und hierzu eine Lösung von 52 cm' Äthylen- imin in 200 cm' Wasser gegeben. Nach 30 minutigem Erwärmen auf 60 C unter Rück flusskühlung werden 300 eins Wasser zuge setzt und die Mischung abgekühlt. Das ab geschiedene 01 wird mit 300 cm3 Wasser gewaschen und durch einstündiges Erhitzen im Vakuum auf 100 C vom gelösten Wasser und Methanol befreit.
Das nach dem Erkal ten erhaltene zähe Harz enthält 14,4 % N.
2. 151 g 2-Mercaptothiazolidin-2-methyl- äther werden in 200 cm' Methanol gelöst und hierzu eine Lösung von 116 g Chloräthyl- aminochlorhydrat in 400 eins Lauge (= 80 g Na0H) gegeben. Die Umsetzung und Aus- fällung des fertigen Produktes wird wie in Beispiel 1 durchgeführt.
Process for the preparation of a resin from nereaptothiazolidine-2-methyl ether. It has already been proposed to convert xanthogenates of the various alcohols with ethylene imine or with chloromhylamine to form mercaptothiazolidine ethers.
It has now been found that these mercaptothiazolidine ethers are capable of a number of reactions. The conversion of the mercaptothiazolidine ethers with the ring-shaped ethylenimine is of technical importance.
The subject of the present patent is a process for the production of a new product, which is characterized in that 2-mercaptothiazolidine-2-methyl ether and ethyleneimine are reacted. The product obtained in this way is intended to be used as an intermediate product, as a textile auxiliary or vulcanization accelerator. Instead of ethyleneimine, it is also possible to use equivalent amounts of haloethylamine with the amount of alkali corresponding to the halogen.
<I> Examples: </I> 1. 151 g of 2-mercaptothiazolidine-2-methyl-ether are dissolved in 200 cm of methanol and a solution of 52 cm of ethylene imine in 200 cm of water is added. After 30 minutes of reflux heating at 60 ° C., 300 liters of water are added and the mixture is cooled. The separated oil is washed with 300 cm3 of water and freed from dissolved water and methanol by heating in vacuo at 100 ° C. for one hour.
The tough resin obtained after cooling contains 14.4% N.
2. 151 g of 2-mercaptothiazolidine-2-methyl ether are dissolved in 200 cm 'of methanol and a solution of 116 g of chloroethyl aminochlorohydrate in 400 liters of lye (= 80 g of NaOH) is added. The conversion and precipitation of the finished product is carried out as in Example 1.
