Description
Verfahren zur Darstellung einer Verbindung anit hydrierten Ringsystem. Cxegerrstarrd dieses Zusatzpatentes ist ein Verfahren zur Darstellung einer Verbindung voll folgender Konstitutiv i
EMI0001.0009
welches dadurch gekennzeichnet ist, dali man 1Vlaleitis < tureariliyclrid mit Phenylbutadien kon densiert.
Die neue Verbindung soll zur Her stellung von Farbstoffen, pharinazeutisehen Produkten und Riechstoffen verwendet wer den.
<I>Beispiel:</I> 7,5 Gewichtsteile 3Taieitisätireanliydrid und 10 Gewichtsteile Phenylbisi:adien werden bei Wasserbadtemperatur vorsichtig so lange erhitzt, bis heftiges Aufsieden der Liisung das Einsetzen der Reaktion anzeigt. 1ATan unterbricht das Erwärmen, lässt die Reaktion zu Ende gehen und erhitzt dann noch eventuell unter Zusatz einer kleinen Benzol menge - zur Vervollständigung der Um setzung etwa 10 Minuten lang zurn Siedet).
Das Umsetzungsprodukt beginnt sich ge wöhnlich schon in der Wärme als weisse Kristallmasse abzuscheiden; beine Abkühlen erstarrt das Cxanze zii einem Kristallkuchen.
Zur Analyse wurde die Substanz aus hoehsiedendern Ligroin unter Benzolzusatz umkristallisiert und hierbei in rein weissen, harten l'ristallnadeln vorn Schmelzpunkt 12U" (nach kurzem Sintern) erhalten.
Das 3-Pheuyl-0'-cis-o-tetraliydroplital- säureanhydrid ist in den gebräuchlichsten organischen Lösungsmitteln auch in der Kälte gilt löslich, schwer dagegen in Wasser, Ligroin Lind Petroläther. Brom in Chloroform wirkt in der Kälte nicht ein. Permanganat- Soda dagegen wird augenblicklich reduziert. Von siedendem Wasser wird es nicht ohne weiteres aufgenommen, leicht hingegen von wässerigem Allzali.

EMI0001.0009
which is characterized in that 1Vlaleitis <tureariliyclrid condenses with phenylbutadiene.
The new compound is to be used to manufacture dyes, pharinazeutisehen products and fragrances.
<I> Example: </I> 7.5 parts by weight of 3-component anhydride and 10 parts by weight of phenylbisi: adiene are carefully heated at water bath temperature until the solution boils vigorously to indicate the onset of the reaction. 1ATan interrupts the heating, allows the reaction to come to an end and then heats it up, possibly with the addition of a small amount of benzene - to complete the reaction, it boils for about 10 minutes).
The reaction product usually begins to separate out as a white crystal mass when heated; Upon cooling, the cxanze solidifies into a crystal cake.
For the analysis, the substance was recrystallized from high-boiling ligroin with the addition of benzene and obtained in pure white, hard crystal needles with a melting point of 12U "(after brief sintering).
3-Pheuyl-0'-cis-o-tetraliydroplitalic anhydride is soluble in the most common organic solvents, even in the cold, but difficult in water, ligroin and petroleum ether. Bromine in chloroform has no effect in the cold. Permanganate soda, on the other hand, is reduced instantly. It is not readily absorbed by boiling water, but it is easily absorbed by watery Allzali.
