Description

Konservierungsmittel Zusatz zum Patent 724 274 Das Patent 724:274 betrifft ein Verfahren zum Konservieren technischer Stoffe und Präparate unter Verwendung von Alkylarylketonen der allgemeinen Formel R # C 0 # Ar # O H als Konservierungsmittel, in welcher R einen aliphatischen, gegebenenfalls substituierten Kohlenwasserstoffrest von höchstens q. Kohlenstoffatomen und Ar einen aromatischen Kohlenwasserstoffrest, vorzugsweise einen Benzolrest, der auch Substituenten enthalten kann, bedeutet. Diese Alkylarylketone besitzen vorzügliche Konservierungseigenschaften. Man kann sie den zu konservierenden Stoffen und Präparaten jedoch im allgemeinen nur durch feine mechanische Verteilung einverleiben, da sie nur unter Zuhilfenahme von Fetten und Ölen löslich sind, die bei den in Frage kommenden Materialien und Präparaten in vielen Fällen nicht anwendbar sind.Preservative additive to patent 724 274 The patent 724: 274 relates to a method for preserving technical substances and preparations using of alkylaryl ketones of the general formula R # C 0 # Ar # O H as preservatives, in which R is an aliphatic, optionally substituted hydrocarbon radical of at most q. Carbon atoms and Ar an aromatic hydrocarbon radical, preferably denotes a benzene radical, which may also contain substituents. These alkyl aryl ketones have excellent preservation properties. One can however, they generally only pass through the substances and preparations to be preserved fine mechanical distribution, since they can only be achieved with the help of fats and oils are soluble in the materials and preparations in question are not applicable in many cases.

In Weiterbildung dieses Verfahrens wurde nun gefunden, daB die Alkalisalze der Alkylarylketone von der allgemeinen Formel R - C O - Ar . O H wasserlöslich sind und in bezug auf ihre konservierende Wirkung den Ketonen selbst in keiner Weise nachstehen. Man kann also nunmehr die Ketone in Form dieser Salze in wäBriger Lösung den zu konservierenden technischen Stoffen und Präparaten, wie Stärkepräparaten, Caseinpräparateri, kosmetischen und pharmazeutischen Zubereitungen, Häuten, Brühen zum Einweichen und Gerben von Häuten usw;, außerordentlich leicht -einverleiben, wobei eine gleichmäßige Verteilung der Mittel gewährleistet ist.In a further development of this process it has now been found that the alkali salts of the alkylaryl ketones of the general formula R - C O - Ar. O H water soluble and with regard to their preservative effect are in no way the ketones themselves lag behind. So you can now get the ketones in the form of these salts in aqueous solution the technical substances and preparations to be preserved, such as starch preparations, Casein preparations, cosmetic and pharmaceutical preparations, skins, broths for soaking and Tanning of hides, etc., extremely easy to incorporate, with a uniform Distribution of funds is guaranteed.

An Stelle der Alkalisalze kann man auch andere geeignete wasserlösliche Salze der Alkylarylketone .anwenden, wie z. B. Salze mit starken organischen Basen u. dgl.Instead of the alkali salts, other suitable water-soluble salts can also be used Use salts of the alkylaryl ketones, e.g. B. Salts with strong organic bases and the like

Die Überführung der Alkylarylketone der allgemeinen Formel R - C 0 - Ar . O H in die wasserlöslichen Salze erfolgt in üblicher Weise durch Einwirkung einer berechneten Menge der Basen, z. B. Ätznatron, auf die im Arylrest hydroxylsubstituierten Alkylarylketone. Mau kann dabei in wäßrigem Medium arbeiten, erhält jedoch besonders gut kristallisierte Produkte, wenn man die Ketone in Benzol löst und die Lösung allmählich mit konzentrierter wäßriger Ätzalkalilösung versetzt und das sich abscheidende kristalline Phenölat isoliert.The conversion of the alkylaryl ketones of the general formula R - C 0 - Ar. O H in the water-soluble salts takes place in the usual manner by action a calculated amount of the bases, e.g. B. caustic soda, on the hydroxyl-substituted in the aryl radical Alkyl aryl ketones. Mau can work in an aqueous medium, but receives special well crystallized products if you dissolve the ketones in benzene and the solution gradually mixed with concentrated aqueous caustic alkali solution and the precipitating crystalline phenolate isolated.

Die Anwendung der wasserlöslichen Salze der Alkylarylketone der allgemeinen Formel R - C O - Ar . 0 H, für die als Beispiele die Natrium- oder Kaliümsalze des Methyl-4-oxy-phenylketons; Äthyl-q.-oxyphenylketons, n-Propyl-4-oxyphenylketons; n-Propyl-3-methyl-q.-o3fyphenylketons, n-Bütyl-g.-oxyphenylketons, Isobutyl-4-oxyphenylketons, s-Oxy-5-butyrylbiphenyl usw. zu nennen sind, ergibt sich ohne weiteres aus dem Vorstehenden. Die Konservierungsmittel werden den zu konservierenden Mitteln in Form wäßriger Lösungen zugesetzt oder einverleibt.The application of the water-soluble salts of the alkylaryl ketones of the general Formula R - C O - Ar. 0 H, for which, as examples, the sodium or potassium salts of Methyl-4-oxy-phenyl ketone; Ethyl q.-oxyphenyl ketone, n-propyl-4-oxyphenyl ketone; n-propyl-3-methyl-q.-o3-phenyl ketone, n-butyl-g.-oxyphenyl ketone, isobutyl-4-oxyphenyl ketone, s-oxy-5-butyrylbiphenyl, etc., are readily apparent from the foregoing. The preservatives are the agents to be preserved in the form of water Solutions added or incorporated.

Beispiel Einen Carraghenschleim, den man als Grundlage für die Herstellung von Hautgelees u. dgl: verwenden kann, stellt man in der Weise her, daß man qlJ Gewichtsteile Gärraghenschleim (1: 1g) mit 24 Gewichtsteilen Glycerin und 24 Gewichtsteilen Wasser, in dem 3 Gewichtsteile Weizenstärke angequollen sind, innig vermischt. Zur Konservierung des Carraghenschleims werden im Wasser 0,15°/o (auf die Gesamtmasse berechnet) p-Butyrylphenolnatrium gelöst, das man durch Umsetzung einer Benzollösung von p-Butyrylphenol mit der berechneten Menge einer konzentrierten wäßrigen Ätznatronlösung in Form eines kristallinen Niederschlages mit dem Schmelzpunkt 62° erhält.EXAMPLE A Carraghenschleim, which can be used as a basis for the production of skin jellies and the like: is prepared in such a way that qlJ parts by weight of fermented raghane gum (1: 1g) with 24 parts by weight of glycerine and 24 parts by weight of water, in which 3 parts by weight Wheat starch are swollen, intimately mixed. To preserve the Carraghenschleims 0.15% (calculated on the total mass) p-butyrylphenol sodium is dissolved in the water, which is obtained by reacting a benzene solution of p-butyrylphenol with the calculated amount of a concentrated aqueous caustic soda solution in the form of a crystalline precipitate with the melting point 62 ° received.
