Description
Verfahren zur Darstellung von homologen Jodmethansulfonsäuren und ihren Salzen Durch das Patent 532 766 und seine Zusätze sind Verfahren zur Darstellung von jodmethansulfonsäure geschützt. Diese bestehen darin, daß man entweder im Methylenj odid durch Behandeln mit geeigneten Sulfiten ein Jodatom durch den Sulfonsäurerest ersetzt oder in Halogenmethansulfonsäuren durch Erhitzen mit Salzen der jodwasserstoffsäure das Halogen gegen Jod austauscht.Process for the preparation of homologous iodomethanesulfonic acids and their salts by patent 532,766 and its additions are methods of representation protected by iodomethanesulfonic acid. These consist in that one either in the methylene j odide an iodine atom through the sulfonic acid residue by treating with suitable sulfites replaced or in halomethanesulfonic acids by heating with salts of hydroiodic acid replaces the halogen with iodine.
In weiterer Ausbildung der Verfahren wurde gefunden, daß man zu homologen jodmethansulfonsäuren gelangt, wenn man gemäß dem Patent 532 766 an Stelle von Methylenjodid Homologe des Methylenjodids mit Sulfiten in Reaktion bringt bzw. wenn man gemäß den Patenten 551 145 und 562 5o1 in homologen Halogenmethansulfonsäuren bzw. deren Salzen durch Einwirken von Salzen der jodwasserstoffsäure das Halogen gegen Jod austauscht.In a further development of the process it was found that one is too homologous Iodomethanesulfonic acids are obtained if, according to Patent 532,766, instead of methylene iodide Homologues of methylene iodide with sulfites in reaction or if one according to the patents 551 145 and 562 501 in homologous halomethanesulfonic acids and their Salts the halogen against iodine by the action of salts of hydriodic acid exchanges.
Daß sich die Homologen des Methylenjodids mit den Salzen der schwefligen Säure in einheitlicher Reaktion unter Ersatz nur des einen der beiden am gleichen Kohlenstoffatom stehenden Jodatome durch den Sulfonsäurerest würden umsetzen lassen, erscheint im Hinblick auf die bekannte große Reaktionsfähigkeit des Jods überraschend und war auf Grund des Bekannten nicht vorauszusehen.That the homologues of methylene iodide and the salts of the sulphurous Acid in uniform reaction, replacing only one of the two on the same Carbon atom standing iodine atoms through the sulfonic acid residue would be converted, appears surprising in view of the well-known high reactivity of iodine and could not be foreseen due to the familiar.
Die Homologen der jodmethansulfonsäure bzw. ihre Salze sollen als Zwischenprodukte Verwendung finden. Sie haben sich besonders auch als wertvolle Röntgenkontrastmittel erwiesen.The homologues of iodomethanesulfonic acid or its salts are said to be Find intermediate products use. They have proven to be particularly valuable as well X-ray contrast medium proven.
Beispiel i 197,4 Gewichtsteile Aethylidenjodid werden in 36o Gewichtsteilen
Wasser mit 176,4 Gewichtsteilen neutralem Natriumsulfit 48 Stunden in einem geschlossenen
Gefäß bei 95' geschüttelt. Die von wenig unverändertem Aethylidenj odid abgetrennte
Flüssigkeit wird bei niedriger Temperatur zur Trockne verdampft. Das zurückbleibende
Salzgemisch wird zur Entfernung von Natriumjodid mit
Aceton ausgezogen
und das darin Unlösliche aus l# bis 4. Teilen Methvlalkohol umkristalli-
Die Verwendung anderer Alkylidenjodide, wie z. B. n-Butylidenjodid, an Stelle von Propylidenjodid führt zu entsprechenden anderen Homologen der jodmethansulfonsäure bzw. deren Salzen.The use of other alkylidene iodides, such as. B. n-butylidene iodide, instead of propylidene iodide leads to corresponding other homologues of iodomethanesulfonic acid or their salts.
Beispiel 3 a6,65 Gewichtsteile a-chloräthan-a-sulfonsaures Natrium werden in der dreifachen Menge Wasser mit 16 Gewichtsteilen Natriumjodid 8 Stunden auf z8o bis xgo ° im geschlossenen Gefäß erhitzt. Das Reaktionsgemisch wird zur Trockne verdampft. Das entstandene Natrium--, salz der a-Jodäthan-a-sulfonsäure wird durch mehrfaches Umkristallisieren aus Alkohol gereinigt.Example 3 a6.65 parts by weight of a-chloroethane-a-sulfonic acid sodium are in three times the amount of water with 16 parts by weight of sodium iodide for 8 hours heated to z8o to xgo ° in a closed vessel. The reaction mixture becomes Dry evaporates. The resulting sodium, salt of a-iodoethane-a-sulfonic acid is purified by repeated recrystallization from alcohol.
