Es ist bekannt (vgl. USA.-Patentschrift 2 735 870), daß man Pinan durch Oxydation mittels Sauerstoff — ohne weitere Konzentrierung — zu einem über 5O°/oigen Pinanhydroperoxyd oxydieren kann. Es ist ferner bekannt (vgl Journ. org. Chem., 24 [1959], S. 1084 ff.), daß sich auch p-Menthan mit Sauerstoff oxydieren läßt. Infolge der starken Bildung von Nebenprodukten jedoch, besonders von Säuren, die verzögernd auf die weitere Bildung von p-Menthanhydroperoxyd wirken, kann nur ein Hydroperoxydgehalt von höchstens 25 bis 35% erreicht werden. Die Herstellung von über 50%igem p-Menthanhydroperoxyd gelingt nur in einem apparativ sehr aufwendigen und kostspieligen Verfahren (vgl. deutsche Auslegeschrift 1 082 255), wobei die Hydroperoxydlösungen von Nebenprodukten, besonders von Säuren, befreit werden und die Lösungen konzentriert werden müssen.It is known (see US Pat. No. 2,735,870) that pinane can be oxidized by means of oxygen - without further concentration - can oxidize to a pinane hydroperoxide of more than 5O%. It is also known (cf. Journ. org. Chem., 24 [1959], pp. 1084 ff.) that p-menthane also reacts with oxygen can oxidize. However, due to the strong formation of by-products, especially acids, the Only a hydroperoxide content can delay the further formation of p-menthane hydroperoxide of a maximum of 25 to 35% can be achieved. The production of over 50% p-menthane hydroperoxide can only be achieved with a very complex and costly process (cf. German Auslegeschrift 1 082 255), whereby the hydroperoxide solutions of by-products, especially of acids, and the solutions need to be concentrated.
Beide Hydroperoxyde besitzen in etwa 50%iger Stärke großes Interesse als Polymerisationsbeschleuniger z. B. für Butadien.Both hydroperoxides, in their 50% strength, are of great interest as polymerization accelerators z. B. for butadiene.
Gegenstand der Erfindung ist ein einfaches und wirtschaftliches Verfahren zur Herstellung von Hydroperoxydgemischen gesättigter Terpene durch Oxydation von Terpenkohlenwasserstoffen mit sauerstoffhaltigen Gasen bei Temperaturen von 80 bis 150° C bis zu einem Hydroperoxydgehalt von etwa 50 bis 63 Gewichtsprozent, das dadurch gekennzeichnet ist, daß man Gemische von Terpenkohlenwasserstoffen einsetzt, die aus 33 bis 75 Gewichtsprozent Pinan, 67 bis 25 Gewichtsprozent p-Menthan und gegebenenfalls anderen gesättigten Terpenen bestehen. The invention is a simple and economical process for the production of Hydroperoxide mixtures of saturated terpenes by oxidation of terpene hydrocarbons with oxygenated ones Gases at temperatures from 80 to 150 ° C up to a hydroperoxide content of approx 50 to 63 percent by weight, which is characterized in that mixtures of terpene hydrocarbons used, which consists of 33 to 75 percent by weight pinane, 67 to 25 percent by weight p-menthane and optionally other saturated terpenes.
Die Ausbeuten liegen hierbei über 90% der Theorie. Überraschenderweise ist eine Konzentrierung der Hydroperoxydgemische erfindungsgemäß nicht nötig, und die Bildung von Nebenprodukten, besonders von Säuren, die auf die weitere Bildung von Hydroperoxyd verzögernd wirken können, ist beim Einsatz von p-Menthan enthaltenden Gemischen aus Pinan und anderen gesättigten Terpenen so weit hintangehalten, daß eine Beseitigung, z.B. eine Auswaschung der Säuren, sich erübrigt.The yields here are over 90% of theory. Surprisingly, there is a focus the hydroperoxide mixtures are not necessary according to the invention, and the formation of by-products, especially of acids, which can have a retarding effect on the further formation of hydroperoxide when using mixtures of pinane and other saturated terpenes containing p-menthane kept so far back that elimination, e.g. washing out of the acids, is unnecessary.
Erfindungsgemäß können auch technisch reine Gemische gesättigter Terpene, die gegebenenfalls geringe Mengen ungesättigter Terpene enthalten, oxydiert werden. Im Fall des Vorhandenseins ungesättigter Terpene in den Ausgangsgemischen steigt im Verlauf der Oxydation der Hydroperoxydgehalt besonders rasch und erreicht besonders hohe Werte, wenn die Jodzahlen der zur Oxydation eingesetzten Gemische unter 3 (Kaufmann) liegen. Bei Jod-Verfahren zur Herstellung von Hydroperoxydgemischen gesättigter TerpeneAccording to the invention, technically pure mixtures of saturated terpenes, which optionally contain small amounts of unsaturated terpenes, are oxidized. In the case of the presence of unsaturated Terpenes in the starting mixtures increase in the course of the oxidation, the hydroperoxide content particularly quickly and reaches particularly high values if the iodine numbers are those used for oxidation Mixtures below 3 (Kaufmann) are. In the iodine process for the production of hydroperoxide mixtures saturated terpenes

zahlen unter 3 erübrigt sich auch eine Reinigung bzw. Destillation des Ausgangsgemisches vor der Oxydation. Numbers below 3 also mean that there is no need to purify or distill the starting mixture prior to oxidation.
.Der Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß man auf diese Weise Terpengemische oder Terpenfraktionen, die Pinen neben anderen Terpenen, besonders neben monocyclischen Terpenen enthalten — wie sie beispielsweise als Nebenprodukte bei der Kampfersynthese anfallen — nach der Hydrierung, die in bekannter Weise ausgeführt werden kann, ohne weitere Reinigung, durch Oxydation und ohne anschließende Konzentrierung oder Wäsche zu hochwertigen Katalysatoren verarbeiten kann. Die so erhaltenen, etwa 50%igen Hydroperoxydgemische können mit sehr gutem Erfolg als Polymerisationsbeschleuniger, z. B. für Polyester, eingesetzt werden..The advantage of the method according to the invention is that in this way terpene mixtures or fractions, the pinene in addition to other terpenes, especially in addition to monocyclic terpenes - such as, for example, as By-products in the camphor synthesis are obtained - after the hydrogenation, which is carried out in a known manner can be, without further purification, by oxidation and without subsequent concentration or can process laundry into high-quality catalysts. The thus obtained, about 50% Hydroperoxide mixtures can be used with very good success as a polymerization accelerator, e.g. B. for polyester, can be used.
Folgende Beispiele sollen das Verfahren näher erläutern.The following examples are intended to explain the process in more detail.
Als Ausgangsmaterial dient ein Terpengemisch, das zu etwa 60% aus Pinen, zu etwa 25% aus Dipenten und zum Rest aus anderen monocyclischen Terpenen und etwas Camphen besteht. Dieses Terpengemisch hydriert man in bekannter Weise zu einem Gemisch gesättigter Terpene, das etwa 60% Pinan neben etwa 31% p-Menthan und zum Rest aus anderen gesättigten Terpenen, wie Camphan, besteht. Jodzahl ist 1,8. 500 g dieses Gemisches gesättigter Terpene werden ohne weitere Reinigung — zusammen mit 0,25% Hydroperoxyd als Startmittel — in einem doppelmanteligen Oxydationsrohr (ca. 1000 ml Inhalt), das mittels einer FlüssigkeitA terpene mixture is used as the starting material, about 60% pinene and about 25% Dipentene and the rest of other monocyclic terpenes and some camphene. This Terpene mixture is hydrogenated in a known manner to a mixture of saturated terpenes, which is about 60% pinane in addition to about 31% p-menthane and the rest from other saturated terpenes, such as camphane, consists. Iodine number is 1.8. 500 g of this mixture of saturated terpenes are used without further purification - together with 0.25% hydroperoxide as a starting agent - in a double-jacketed oxidation tube (approx. 1000 ml content), which by means of a liquid
