Description
Verfahren zur Herstellung eines Kondensationsproduktes. Es ist bekannt, dass Trimethylhydrochinon mit Phytol bezw. Phy tylhalogeniden oder Phytadien zu dl-a-Tocopherol kondensiert werden kann.
Es wurde gefunden; dass ein bisher unbe kanntes Kondensationsprodukt entsteht, wenn Trimethylhydrochinon mit Acetylphytol kon densiert wird. Das gebildete Kondensations produkt kann durch Acetylierung in eine kristalline Verbindung überführt werden.
Das neue Kondensationsprodukt ist eine seifenartige Paste, löslich in Petroläther; es reduziert Kalipermanganat in der Kälte und Goldchlorid in der Wärrne. Das durch Be handlung mit Acetanhydrid daraus entstan dene Acetylderivat destilliert unter 0,08 mm Druek bei 2200 und zeigt nach Umkristalli- sieren aus Methylalkohol einen Schmelzpunkt von<B>600.</B> Es vermag Permanganat in der Kälte nicht zu reduzieren.
Durch Hydrolyse mit methylalkoholischer Schwefelsäure erhält man daraus ein Öl, welches Goldchlorid re- duziert und durch thermische Zersetzung Durohydrochinon bildet.
Das Kondensationsprodukt soll zur Her stellung von Heilmitteln mit Vitamin E-Wir- kung und als Zwischenprodukt für die Ge winnung weiterer pharmazeutisch wichtiger Verbindungen Verwendung finden. <I>Beispiel:</I> 185 Teile Aeetylphytol in 200 Teilen Benzol werden im Verlauf einer Stunde, zu einem Gemisch von 74 g Trimethylhydro- chinon in 200 cm' Benzol und 40 g wasser freiem Zinkchlorid, gelöst in 450<B>cm-'</B> trok- kenem Äther, unter Rühren bei 40 zugesetzt.
Dann wird noch 4 Stunden unter Rückfluss schwach gekocht, darauf mit Wasser versetzt und die Benzol-Ätherschicht nacheinander reit Wasser, verdünnter Salzsäure, verdünnter Natronlauge und mehrmals mit Wasser ge waschen. Nach dem Trocknen mit Natrium sulfat destilliert man die Lösungsmittel ab. Der Rückstand bildet eine seifenartige Masse. Man löst in warmem Petroläther, wobei das Kondensationsprodukt als flockiger Nieder schlag beim Erkalten ausfällt.
Die Lösung wird zentrifugiert, der Petroläther abgegossen und der Rückstand im Vakuum getrocknet. Man erhält 190 Teile einer schmierseifen- artigen Masse.
Durch Acetylieren mit 1'/E Teilen Essig säureanhydrid bei 140-1600 erhält man ein bei 220'/0,08 mm destillierendes Öl, welches aus 3 Teilen Methylalkohol umkristallisiert werden kann. Man erhält fast weisse Kristalle vom F. 60 .
Process for the production of a condensation product. It is known that trimethylhydroquinone with Phytol BEzw. Phy tylhalogeniden or phytadiene can be condensed to dl-a-tocopherol.
It was found; that a previously unknown condensation product is formed when trimethylhydroquinone is condensed with acetylphytol. The condensation product formed can be converted into a crystalline compound by acetylation.
The new condensation product is a soap-like paste, soluble in petroleum ether; it reduces potassium manganate in the cold and gold chloride in the warm. The acetyl derivative formed therefrom by treatment with acetic anhydride distills under 0.08 mm pressure at 2200 and, after recrystallization from methyl alcohol, shows a melting point of <B> 600. </B> It is unable to reduce permanganate in the cold.
By hydrolysis with methyl alcoholic sulfuric acid, an oil is obtained which reduces gold chloride and forms durohydroquinone through thermal decomposition.
The condensation product is intended to be used for the manufacture of medicinal products with vitamin E effects and as an intermediate product for the production of other pharmaceutically important compounds. <I> Example: </I> 185 parts of acetylphytol in 200 parts of benzene are converted over the course of one hour to a mixture of 74 g of trimethylhydroquinone in 200 cm 'of benzene and 40 g of anhydrous zinc chloride, dissolved in 450 cm - '</B> dry ether, added with stirring at 40.
The mixture is then gently refluxed for 4 hours, then treated with water and the benzene-ether layer is washed successively with water, dilute hydrochloric acid, dilute sodium hydroxide solution and several times with water. After drying with sodium sulfate, the solvents are distilled off. The residue forms a soap-like mass. It is dissolved in warm petroleum ether, the condensation product precipitating out as a flaky precipitate on cooling.
The solution is centrifuged, the petroleum ether is poured off and the residue is dried in vacuo. 190 parts of a soft soap-like mass are obtained.
Acetylating with 1 part of acetic anhydride at 140-1600 gives an oil which distills at 220 / 0.08 mm and which can be recrystallized from 3 parts of methyl alcohol. Almost white crystals of F. 60 are obtained.
