Description

Verfahren zur Herstellung der magnesiumsalze der i-1Vtethyl-4-isopropylbenzolsulfonsäuren und ihrer Substitutionsprodukte Es wurde gefunden, daß die gemäß dem hauptpatent 466 36o herstellbaren Magnesiumsalze von r-Methy1-4-isopropylbenzolsulfonsäuren und ihrer Substitutionsprodukte auch gewonnen werden können durch Umsetzung der freien Sulfonsäuren mit löslichen lE-Zagnesiurnsalzen oder auch mit dem Oxyd, Hydroxyd oder Carbonat des- Magnesiums. Beispiel In eine erwärmte, wäßrige Lösung von roo Teilen z-Methyl-d.-isopropylbenzol-2-sulfonsäure in rooo Teilen Wasser werden unter Rühren allmählich rd. Teile MagnesiumhYdroxyd eingetragen, wobei sich sofort das schwer lösliche Magnesiumsalz der r-Methyld.-isopropylbenzol-2-sulfonsriure auszuscheiden beginnt. Nach mehrstündigem Rühren läßt man abkühlen, saugt ab und trocknet.Process for the preparation of the magnesium salts of the i-1Vtethyl-4-isopropylbenzenesulfonic acids and their substitution products. It has been found that those according to the main patent 466 36o producible magnesium salts of r-Methy1-4-isopropylbenzenesulfonic acids and their substitution products can also be obtained by converting the Free sulphonic acids with soluble IE-zinc salts or with the oxide, hydroxide or carbonate of magnesium. Example In a heated, aqueous solution of roo Parts of z-methyl-d.-isopropylbenzene-2-sulfonic acid in rooo parts of water are added Stir gradually around parts of magnesium hydroxide added, and immediately the the sparingly soluble magnesium salt of r-Methyld.-isopropylbenzene-2-sulfonic acid to be separated out begins. After stirring for several hours, the mixture is allowed to cool, filtered off with suction and dried.
