Description
Verfahren zur Herstellung eines Umsetzungsproduktes der ühlorsulfonsäure. Im Hauptpatent ist ein Verfahren zur Herstellung eines Umsetzungsproduktes der Chlorsulfonsäure beschrieben, bei dem man Chlorsulfonsäure mit Formamid behandelt.
Es wurde nun gefunden, dass man ein ähnliches technisch wertvolles Produkt auch erhält, wenn man Chlorsulfonsäure mit Harn stoff behandelt. Hierbei entsteht ein bei gewöhnlicher Temperatur festes Produkt, das auch bei höheren Temperaturen beständig ist.
Die -Umsetzung kann durch einfaches Ver mischen der Ausgangsstoffe bei gewöhnlicher Temperatur erfolgen, wobei durch Kühlung dafür Sorge getragen wird, dass die Tempe ratur nicht zu hoch steigt. Es ist vorteilhaft, nach völligem Vermischen der Ausgangs stoffe zwecks Vervollständigung der Um setzung das Gemisch mässig zu erwärmen, z. B. auf 50 bis 60 C. Man kann auch in Gegenwart von nicht oder schwer sulfonier- baren Lösungsmitteln arbeiten, beispielsweise von Tetrachlorkohlenstoff, Tetrachloräthan oder Nitrobenzol.
Es wird ein neues technisch wertvolles Produkt erhalten, das sich z. B. zur Ein führung von Schwefelsäureestergruppen in Hydroxylgruppen enthaltende organische Ver bindungen, insbesondere solche, die olefinische Doppelbindungen enthalten, eignet.
Beispiel: In 116 Gewichtsteile Chlorsulfonsäure trägt man unter Kühlung auf 0 bis 10 C und gutem Rühren etwa 60 Gewichtsteile Harnstoff ein und verrührt die Mischung so lange bei gleicher Temperatur, bis völlige Lösung eingetreten ist. Man erhält ein festes Produkt, das auch bei höherer Temperatur beständig ist. Bei Verwendung der doppelten Menge Chlorsulfonsäure entsteht ein flüssiges Gemisch, das das beschriebene Produkt ent hält und gleichfalls bei höheren Temperaturen beständig ist.
Process for the preparation of a reaction product of chlorosulfonic acid. The main patent describes a process for the preparation of a reaction product of chlorosulfonic acid, in which chlorosulfonic acid is treated with formamide.
It has now been found that a similar technically valuable product is also obtained if chlorosulfonic acid is treated with urea. This creates a product that is solid at normal temperature and is also stable at higher temperatures.
The conversion can be carried out by simply mixing the starting materials at normal temperature, with cooling being used to ensure that the temperature does not rise too high. It is advantageous, after complete mixing of the starting materials in order to complete the implementation to heat the mixture moderately, z. B. to 50 to 60 ° C. It is also possible to work in the presence of solvents which cannot be sulfonated or are difficult to sulfonate, for example carbon tetrachloride, tetrachloroethane or nitrobenzene.
A new technically valuable product is obtained, which z. B. for introducing sulfuric ester groups into hydroxyl-containing organic compounds, especially those containing olefinic double bonds, is suitable.
Example: About 60 parts by weight of urea are added to 116 parts by weight of chlorosulfonic acid while cooling to 0 to 10 ° C. and stirring well and the mixture is stirred at the same temperature until complete dissolution has occurred. A solid product is obtained which is stable even at higher temperatures. When using twice the amount of chlorosulfonic acid, a liquid mixture is created that contains the product described and is also resistant at higher temperatures.
