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.
