Description

Verfahren zur Herstellung von Salzen der 1-1Wethyl-4-isopropylbenzolsulfosäuren und ihrer Substitutionsprodukte Es wurde gefunden, daß die bisher unbekannten, schwer löslichen Magnesiumsalze der Sulfosäuren des i-Methyl-d.-isopropylbenzols (p-Cyrnols) und seiner Substitutionsprodükte hergestellt werden können durch Umsetzung löslicher Salze dieser Sulfosäuren mit löslichen Magnesiumsalzen. Beispiel r 326 Teile i-methyl-.I-isopropylben7ol-2-sulfosaures Natron (S i e v e k i n g , Annalen roh, Seite a57) werden in 3 ooo Teilen Wasser gelöst und eine Lösung von ioo Teilen Magnesiumchlorid unter gutem Rühren zulaufen gelassen. Das sofort ausfallende Magnesiumsalz wird nach einigen Stunden abgesaugt, gewaschen und aus heißem Wasser umkristallisiert. Es bildet farblose Kristalle, die in kaltem Wasser sehr schwer löslich sind. Beispiel e 405 Teile j'-methyi-2-brom-d.-isopropylbenzol-5-sulfosaures Natron (hergestellt aus i-Methyl-2-brom-.l-isopropylbenzol) werden in 3 ooo Teilen Wasser heiß gelöst und eine Lösung von 25o Teilen Bittersalz unter gutem Rühren zulaufen gelassen. Das sofort ausfallende Magnesiumsalz wird nach einigen Stunden abgesaugt, gewaschen und aus heißem Wasser umkristallisiert. Es bildet farblose Kristalle, die in Wasser sehr schwer löslich sind. Beispiel 3 In eine Lösung von 5o Teilen i-methvl-4-isopropylbenzol-3-sulfosaurem Natron in 2 ooo Teilen Wasser werden 3o Teile einer 70prozentigen Chlormagnesiumlauge einlaufen gelassen, wodurch das Magnesiumsalz der i-Methyl-4-isopropy lbenzol-3-sulfosäure als weißer, schwer löslicher Niederschlag abgeschieden wird. Derselbe wird abgesaugt und aus heißem Wasser umkristallisiert. Es bildet ein weißes Kristallpulver, das in Wasser sehr schwer löslich ist.Process for the preparation of salts of 1-1Wethyl-4-isopropylbenzenesulfonic acids and their substitution products It has been found that the hitherto unknown, difficult soluble magnesium salts of the sulfonic acids of i-methyl-d.-isopropylbenzene (p-cyrnol) and its substitution products can be prepared by reacting them more soluble Salts of these sulfonic acids with soluble magnesium salts. Example r 326 parts of i-methyl-.I-isopropylben7ol-2-sulfonic acid Soda (S i e v e k i n g, Annalen roh, page a57) are dissolved in 3,000 parts of water dissolved and a solution of 100 parts of magnesium chloride run in with thorough stirring calmly. The immediately precipitating magnesium salt is sucked off after a few hours, washed and recrystallized from hot water. It forms colorless crystals, which are very sparingly soluble in cold water. Example e 405 parts of j'-methyl-2-bromo-d.-isopropylbenzene-5-sulfonic acid Soda (made from i-methyl-2-bromo-.l-isopropylbenzene) come in 3,000 parts Water dissolved in hot water and a solution of 250 parts of Epsom salt with thorough stirring allowed to run. The immediately precipitating magnesium salt becomes after a few hours suctioned off, washed and recrystallized from hot water. It forms colorless Crystals that are very sparingly soluble in water. Example 3 In a solution of 50 parts of i-methyl-4-isopropylbenzene-3-sulfonic acid sodium in 2,000 parts of water 3o parts of a 70% chlorine magnesium hydroxide solution are run in, as a result of which the magnesium salt of i-methyl-4-isopropylbenzene-3-sulfonic acid as a white, heavy soluble precipitate is deposited. The same is sucked off and out of hot Recrystallized water. It forms a white crystal powder that is very much in water is sparingly soluble.

Die neuen Verbindungen dienen medizinischen Zwecken, insbesondere besitzen sie wurmtreibende Eigenschaften.The new compounds are used for medical purposes, in particular they have worming properties.
