Description

Verfahren zur Herstellung haltbarer wäßriger Emulsionen aus Oxydiphenylen und Tükischrotölen Gemische oder Lösungen von Oxydiphenylen und den üblichen Emulgatoren, wie Seife oder Türkischrotöle, geben beim Verdünnen mit Wasser Emulsionen von sehr geringer Haltbarkeit, aus denen in kurzer Zeit das Oxydiphenyl auskristallisiert.Process for the preparation of durable aqueous emulsions from oxydiphenyls and turkish red oils mixtures or solutions of oxydiphenyls and the usual emulsifiers, such as soap or Turkish red oils, when diluted with water, give emulsions of very high short shelf life from which the oxydiphenyl crystallizes out in a short time.

Es wurde nun gefunden, daß wäßrige Emulsionen, die aus Oxydiphenylen und Türkischrotölen hergestellt sind, durch Zusatz von aromatischen Äthern überraschend gut stabilisiert werden, so daß aus solchen Emulsionen eine Abscheidung des Oxydiphenyls-selbst nach längerem Stehen nicht erfolgt. It has now been found that aqueous emulsions composed of oxydiphenyls and Turkish red oils are produced, surprisingly, by adding aromatic ethers are well stabilized, so that a deposition of the oxydiphenyl itself from such emulsions not done after standing for a long time.

Mit besonderem Vorteil kann man bei diesem Verfahren den Diphenyläther verwenden. Er fällt zusammen mit Oxydiphenyl als Nebenprodukt bei der Druckverseifung von Chlorbenzol zu Phenol an. Diese technisch anfallende Mischung von Oxydiphenyl und Diphenyläther kann sofort zur Herstellung der Emulsionen verwendet werden und bedarf keiner weiteren Aufarbeitung. Diphenyl ether can be used with particular advantage in this process use. It coincides with oxydiphenyl as a by-product of pressure saponification from chlorobenzene to phenol. This industrially obtained mixture of oxydiphenyl and diphenyl ether can be used immediately to prepare the emulsions and does not require any further work-up.

An Stelle des Diphenyläthers kann man aber auch andere aromatische Äther, z. B. Guajacol verwenden. Instead of diphenyl ether, however, other aromatic ones can also be used Ether, e.g. B. use guaiacol.

Beispiel I Eine Mischung, bestehend âus 4 Teilen Oxydiphenyl und 2,5 Teilen Diphenyläther, wird in 3,4 Teilen Türkischrotöl gelöst. Die Lösung läßt sich mit Wasser verdünnen und ergibt eine völlig stabile Emulsion, aus der das Oxydiphenyl nicht auskristallisiert. Example I A mixture consisting of 4 parts of oxydiphenyl and 2.5 parts of diphenyl ether are dissolved in 3.4 parts of Turkish red oil. The solution leaves dilute with water and result in a completely stable emulsion from which the oxydiphenyl not crystallized out.

Beispiel 2 Eine bei der Druckverseifung von Chlorbenzol zu Phenol als Nebenprodukt anffallende Mischung von etwa 4 Teilen p-Oxydiphenyl, 6 Teilen o-Oxydiphenyl und 5,3 Teilen Diphenyläther wird in 8 Teilen Türkischrotöl gelöst und gibt nach Verdünnen mit Wasser eine haltbare Emulsion. Example 2 One in the pressure saponification of chlorobenzene to phenol A by-product mixture of about 4 parts of p-oxydiphenyl, 6 parts o-Oxydiphenyl and 5.3 parts of diphenyl ether are dissolved in 8 parts of Turkish red oil and gives a long-lasting emulsion after dilution with water.

Beispiel3 Teile o-Oxydiphenyl, 8 Teile Türkischrotöl und 4 Teile Guajacol geben eine Lösung, die beim Verdünnen mit Wasser eine haltbare Emulsion liefert. Example 3 parts of o-oxydiphenyl, 8 parts of Turkish red oil and 4 parts Guaiacol give a solution that a durable when diluted with water Emulsion supplies.
