Description
Verfahren zur Darstellung von jodmethansulfonsaurem Zink. Gegenstand vorliegender Erfindung ist ein Verfahren zur Darstellung von jodmethansul- fonsaurem Zink, dadurch gekennzeichnet, dass man chlormethansulfonsaures Zink mit Zinkjodid umsetzt.
Das erhaltene neue Produkt ist ein wert volles Zwischenprodukt für die Herstellung von Mitteln zur Sichtbarmachung von Hohl räumen in menschlichen und tierischen Kör pern mittelst Röntgenstrahlen. Es stellt ein weisses Kristallpulver dar, das sich sehr leicht in Wasser, Alkoholen und Aceton löst, in Äther, Petroläther und Benzol jedoch un löslich ist.
<I>Beispiel:</I> 324 Gewichtsteile chlormetliansulfonsaures Zink werden mit 319 Gewichtsteilen Zink- jodid in 500 Gewichtsteilen Wasser 20 Stun den im geschlossenen Gefäss auf 180-185 erhitzt. Hierauf wird die Reaktionsmasse stark eingedampft und durch Kristallisieren des Reaktionsproduktes aus verdünntem Alkohol das Zinksalz der Jodmethansulfon- säure erhalten.
Hieraus kann man das Na- triumsalz der Jodmethansulfosäure gewinnen indem man die Reaktionsmischung mit Soda heiss umsetzt, vom ausgefallenen Zink hydroxyd, bezw. basischen Zinkkarbonat ab filtriert und nach Eindampfen der Lösung der Natriumsalze das jodmethansulfosaure Natrium durch Kristallisieren aus Methyl alkohol isoliert. Die freie Säure erhält man zum Beispiel aus dem Natriumsalz durch Zusatz starker Salzsäure, Abfiltrieren des ausfallenden Natriumchlorids und Eindampfen der Lösung.
Process for the preparation of zinc iodomethanesulfonate. The present invention relates to a process for the preparation of iodomethanesulphonic acid zinc, characterized in that chloromethanesulphonic acid zinc is reacted with zinc iodide.
The new product obtained is a valuable intermediate product for the manufacture of means for making cavities in human and animal bodies visible by means of X-rays. It is a white crystal powder that dissolves very easily in water, alcohol and acetone, but is insoluble in ether, petroleum ether and benzene.
<I> Example: </I> 324 parts by weight of zinc chloride are heated with 319 parts by weight of zinc iodide in 500 parts by weight of water in a closed vessel to 180-185 hours. The reaction mass is then vigorously evaporated and the zinc salt of iodomethanesulfonic acid is obtained by crystallizing the reaction product from dilute alcohol.
The sodium salt of iodomethanesulfonic acid can be obtained from this by reacting the reaction mixture with hot soda, from the precipitated zinc hydroxide, respectively. basic zinc carbonate is filtered off and, after evaporation of the solution of the sodium salts, the sodium iodomethanesulfonic acid is isolated by crystallization from methyl alcohol. The free acid is obtained, for example, from the sodium salt by adding strong hydrochloric acid, filtering off the precipitating sodium chloride and evaporating the solution.
