Description

Verfahren zur Herstellung eines neuartigen Abkömmlings des a-Phenyläthylalkohols Es ist bekannt, daß man durch Umsetzung von a-Phenyläthylalkohol mit Bernsteinsäureanhydrid den sauren Bernsteinsäureester erhält, doch ist dessen Aufarbeitung und Abtrennung von mitentstandenen Nebenprcdukten umständlich und insbesondere die Isolierung und Reind irstellung seiner in Wasser leicht löslichen und schlecht kristallisierenden Alkali- und Erdalkalisalze mit Schwierigkeiten verbunden.Process for the preparation of a novel derivative of a-phenylethyl alcohol It it is known that by reacting α-phenylethyl alcohol with succinic anhydride the acid succinic acid ester is obtained, but its work-up and separation is of incidental byproducts cumbersome and especially the isolation and Purification of its easily soluble in water and poorly crystallizing Alkali and alkaline earth salts associated with difficulties.

Es wurde nun gefunden, daß man aus den wäßrigen Lösungen der Salze eine gut kristallisierende Doppelverbindung abscheiden kann, wenn man die Salzlösungen mit überschüssigem Calciumchlorid versetzt. It has now been found that the aqueous solutions of the salts a double compound that crystallizes well can be deposited if one uses the salt solutions mixed with excess calcium chloride.

Auf Grund ihrer Löslichkeitseigenschaften kann diese Doppelverbindung leicht von Begleitstoffen abgetrennt und in reiner Form in sehr guter Ausbeute erhalten werden.Due to their solubility properties, this double compound can easily separated from accompanying substances and obtained in pure form in very good yield will.

Das neue Calciumchloriddoppe lsalz besitzt wertvolle therapeutische Eigenschaften und kann als solches oder als Zwischenprodukt zur Herstellung von Heilmitteln verwendet werden. The new calcium chloride double salt has valuable therapeutic properties Properties and can be used as such or as an intermediate in the manufacture of Remedies are used.

Beispiel 6i g a-Phenyläthylalkohol werden mit 50 g Bernsteinsäureanhydrid 21/2 Stunden auf I40° erhitzt und die entstandene Estersäure nach Aufnehmen mit Benzol und Abfiltrieren von geringen Mengen Bernsteinsäure mit der berechneten Menge verdünnter Natronlauge in Lösung gebracht. Die neutrale, wäßrige Lösung des Natriumsalzes wird mit überschüssiger wäßriger Calciumchloridlösung versetzt. Hierbei fällt das Calciumchloriddoppelsalz als weißer kristalliner Niederschlag aus, der abgesaugt und nach dem Nachwaschen mit Wasser zunächst an der Luft und dann bei 50 bis 70" getrocknet wird. Example 6i g of a-phenylethyl alcohol are mixed with 50 g of succinic anhydride Heated 21/2 hours to 140 ° and the ester acid formed after absorption with Benzene and filter off small amounts of succinic acid with the calculated amount diluted sodium hydroxide solution brought into solution. The neutral, aqueous solution of the sodium salt is mixed with excess aqueous calcium chloride solution. This is where it falls Calcium chloride double salt as a white crystalline precipitate, which is sucked off and after washing with water first in the air and then at 50 to 70 " is dried.
