Description
Verfahren zur Darstellung einer Verbindung mit; hydriertem Ringsystem. Gegenstand dieses Zusatzpatentes ist ein Verfahren zur Darstellung eines hydrierten Tetramethyl-anthrachinons, welches dadurch gekennzeichnet ist, dass man Benzochinon mit 1 . 3-Dimethyl-butadien kondensiert. Die neue Verbindung soll zur Herstellung von Farb stoffen Verwendung finden.
<I>Beispiel:</I> i; Gewichtsteile Benzochinon werden mit 5 Volumenteilen 1 .3-Dimethyl-butadien eine Stunde auf dem Wasserbad am Rückfluss- kühler erhitzt. Nach dem Erkalten kristalli siert das neue Produkt aus und wird durch Absaugen und Nachwaschen mit Petroläther isoliert. Es schmilzt roh bei 186-1881 C. Aus Eisessig umkristallisiert, erhält man die Verbindung in weissen Nadeln vom Schmelz punkt 194 C.
Method for representing a connection with; hydrogenated ring system. The subject of this additional patent is a process for the preparation of a hydrogenated tetramethyl-anthraquinone, which is characterized in that benzoquinone with 1. 3-dimethyl-butadiene condensed. The new compound will be used to manufacture dyes.
<I> Example: </I> i; Parts by weight of benzoquinone are heated with 5 parts by volume of 1,3-dimethylbutadiene for one hour on a water bath at a reflux condenser. After cooling, the new product crystallizes out and is isolated by suction and washing with petroleum ether. It melts raw at 186-1881 C. Recrystallized from glacial acetic acid, the compound is obtained in white needles with a melting point of 194 C.
