Description
Verfahren zur Herstellung einer organischen Quecksilberverbindung. Es ist bereits vorgeschlagen worden, Organokomplexquecksilberverbindungen vom Typ R # Hg # OH, worin R einen aromati schen Rest, wie Phenyl, Tolyl usw., dar stellt, mit Phenol und seinen Homologen umzusetzen. Hierbei tritt die Hydroxylgruppe des Phenols mit der Quecksilberverbindung unter Wasserabspaltung in Reaktion. Die dabei entstehenden Quecksilberverbindungen sind praktisch in Wasser unlöslich.
Lässt man Quecksilberverbindungen vom Typ R # Hg # OH auf mehrwertige Phenole, wie Resorcin oder Hydrochinon einwirken, so erhält man ebenfalls Verbindungen, bei denen analog den obengenannten bekannten Verbindungen die vorhandenen Hydroxyl- gruppen mit der Quecksilberverbindung in Reaktion getreten sind, wobei jede pheno- lische Hydroxylgruppe mit einem Mol der Quecksilberverbindung umgesetzt wird.
Es wurde nun gefunden, dass dieser Ge setzmässigkeit Brenzkatechin, ein zweiwer- tiges Phenol, bei dem sich die OH-Gruppen in o-Stellung befinden, nicht folgt. Das Brenz- katechin tritt so in Reaktion mit der Queck silberverbindung R # Hg # OH, dass eine Hy- droxylgruppe frei bleibt.
Es findet somit bei diesem zweiwertigen Phenol eine selektive Umsetzung der Ily- droxylgruppen mit der Quecksilberverbindung statt, die nicht vorauszusehen war.
Gegenstand der Erfindung ist nun ein Verfahren zur Herstellung einer organischen Quecksilberverbindung mit dem Kennzeichen, dass man Brenzkatechin mit Phenylqueck- silberhydroxyd umsetzt, wobei eine Hydroxyl- gruppe des Brenzkatechins an der Reaktion nicht teilnimmt.
Die dabei entstehende neue Quecksilber verbindung zeichnet sich gegenüber den be kannten Reaktionsprodukten aus Phenol und dem Hydroxyd eines mercurierten aromati schen Kohlenwasserstoffes, nämlich R.Hg.OH, durch ihre Löslichkeit in verdünnten wäs- serigen Alkalien aus, deren pH-Wert über dem von Soda liegen muss.
Bedingt durch die vorhandene freie Hydroxylgruppe ist die neue Quecksilberverbindung in den wäs serigen Lösungen dieser Alkalien uniersetzt löslich, da sie sich, wie dies auch aus<B>dem</B> Beispiel 1 hervorgeht, aus solchen Lösungen mit Säuren, wie Kohlensäure, oder mit stark verdünnter Schwefelsäure uniersetzt aus fällen lässt.
Die neue Quecksilberverbindung soll zurr Beispiel als Desinfektions-, gonservierungs- und Saatgutbeizmittel zur Anwendung ge langen.
Beispiel <I>1:</I> 58,8 g Phenylquecksilberhydroxyd und 30 g Brenzkatechin werden innig mitein ander vermischt und in eine Lösung von 16 g NaOH in 1600 cm' Wasser eingetragen. Das Ganze wird etwa 20 Minuten bei Zimmer temperatur geschüttelt, worauf in die Lösung Kohlensäure eingeleitet wird. Es fällt ein weissgrauer Körper aus, der nach dem Aus waschen und Trocknen den Schmelzpunkt 161 0 zeigt.
Ausbeute fast theoretisch. Ge- fundener Quecksilberwert 62,19 %, theore- tischer Quecksilberwert der Monoquecksilber verbindung des Brenzkatechins 51,9 %. Beirpiel <I>2:</I> 29,4 g Phenylquecksilberhydroxyd werden in 500 em8 Wasser in der Siedehitze gelöst. Zu dieser Lösung werden 20 g Brenzkate- chin, gelöst in 50 cm$ Wasser, hinzugefügt.
Es fällt ein weissgrauer Körper aus, der ge waschen und getrocknet den Schmelzpunkt 161 zeigt. Ausbeute und Quecksilberwerte wie bei Beispiel 1.
Process for the production of an organic mercury compound. It has already been proposed to implement organocomplex mercury compounds of the R # Hg # OH type, in which R is an aromatic radical, such as phenyl, tolyl, etc., with phenol and its homologues. The hydroxyl group of the phenol reacts with the mercury compound with elimination of water. The resulting mercury compounds are practically insoluble in water.
If mercury compounds of the R # Hg # OH type are allowed to act on polyvalent phenols such as resorcinol or hydroquinone, compounds are also obtained in which the hydroxyl groups present have reacted with the mercury compound analogously to the above-mentioned known compounds, with each phenol Lische hydroxyl group is reacted with one mole of the mercury compound.
It has now been found that pyrocatechol, a divalent phenol in which the OH groups are in the o-position, does not obey this law. The catechol reacts with the mercury compound R # Hg # OH in such a way that a hydroxyl group remains free.
In the case of this dihydric phenol, there is therefore a selective conversion of the ilyroxyl groups with the mercury compound, which could not be foreseen.
The invention now relates to a method for producing an organic mercury compound with the characteristic that pyrocatechol is reacted with phenylmercuric hydroxide, a hydroxyl group of the pyrocatechol not taking part in the reaction.
The resulting new mercury compound is distinguished from the known reaction products of phenol and the hydroxide of a mercurated aromatic hydrocarbon, namely R.Hg.OH, by its solubility in dilute aqueous alkalis with a pH value above that of soda must lie.
As a result of the free hydroxyl group present, the new mercury compound is unieretzt soluble in the aqueous solutions of these alkalis because, as can also be seen from Example 1, it is obtained from solutions with acids such as carbonic acid or with strongly diluted sulfuric acid can be precipitated out unieretzt.
The new mercury compound is to be used, for example, as a disinfectant, preservative and seed dressing agent.
Example <I> 1: </I> 58.8 g of phenylmercuric hydroxide and 30 g of pyrocatechol are intimately mixed with one another and added to a solution of 16 g of NaOH in 1600 cm 'of water. The whole thing is shaken for about 20 minutes at room temperature, whereupon carbonic acid is introduced into the solution. It turns out a white-gray body which, after washing and drying, has a melting point of 161 °.
Almost theoretical yield. Found mercury value 62.19%, theoretical mercury value of the mono- mercury compound of pyrocatechol 51.9%. Example <I> 2: </I> 29.4 g of phenyl mercury hydroxide are dissolved in 500 em8 of boiling water. 20 g of pyrocatechin dissolved in 50 cm of water are added to this solution.
A white-gray body precipitates, which, washed and dried, has a melting point of 161. Yield and mercury values as in Example 1.
