Description

Desinfektionsmittel In dem Hauptpatent 763 838 sind Desinfektionsmittel beschrieben, bei denen die schwerlöslichen Phenole der Benzol- oder Naphthalinreihe bzw. deren Halogenderivate durch alkylierte aromatische bzw. hydroaromatische sulfonsaure Salze in Lösung gebracht werden. Bei den einfachen Kresolen kann man auf diese Weise Präparate herstellen, die 5o °/o und mehr Kresol enthalten. In manchen Fällen jedoch, insbesondere bei Verwendung von Halogenderivaten der Phenole, genügen die auf die oben bezeichnete Weise hergestellten Präparate bei Herstellung von Lösungen in hartem Wasser nicht allen Anforderungen, insofern, als nach kurzem Stehen Trübungserscheinungen infolge kalkhaltiger Niederschläge auftreten. Man hat bereits versucht, diesen Übelstand dadurch zu beseitigen, daB man bei der Herstellung solcher Desinfektionsmittel wasserlösliche Salze von Phosphorsäuren, die wasserärmer als die Ortho-Phosphorsäuren sind, oder wasserlösliche Salze der Nitriloessigsäure bzw. anderer ähnlich konstituierter Säuren zusetzte.Disinfectants In the main patent 763 838 are disinfectants described in which the sparingly soluble phenols of the benzene or naphthalene series or their halogen derivatives by alkylated aromatic or hydroaromatic sulfonic acid Salts are brought into solution. With the simple cresols one can do this in this way Manufacture preparations containing 50 per cent and more cresol. In some cases, however, especially when using halogen derivatives of phenols, the ones on the suffice Preparations made in the manner described above with the preparation of solutions in hard Water does not meet all requirements, insofar as cloudiness appears after standing for a short time occur as a result of calcareous precipitation. Attempts have already been made to remedy this problem to be eliminated by the fact that water-soluble disinfectants are used in the production of such disinfectants Salts of phosphoric acids, which are lower in water than orthophosphoric acids, or water-soluble salts of nitriloacetic acid or other similarly constituted acids added.

Es hat sich nun gezeigt, daB man in einfacher Weise auch ohne Verwendung derartiger Zusätze zum Ziel kommen kann, wenn man als Emulgatoren an Stelle der einfachen alkylierten aromatischen oder hydroaromatischen Sulfonsäuren Produkte verwendet, die durch Kondensation mit kernkondensierenden Mitteln, wie z. B. Formaldehyd, Acetaldehyd, Chlorschwefel usw., aus den erwähnten Sulfonsäuren hergestellt werden können (vgl. Patentschrift 445 588). Als zweckmäßig hat es sich erwiesen, solche Kondensationsprodukte zu verwenden, bei deren Herstellung auf 2 Mol Sulfonsäure weniger als i Mol Formaldehyd, bis zu i/2 Mol und weniger, zur Anwendung gelangen. Bei Verwendung der erfindungsgemäß benutzten Kondensationsprodukte hat man einmal den Vorteil, daß auch bei Benutzung von chlorierten Kresolen die daraus mit kalkhaltigem Wasser erhaltenen dünnen Gebrauchslösungen bis auf eine unbedeutende Opaleszenz blank bleiben. Darüber hinaus hat sich aber noch gezeigt, daß die Emulgierfähigkeit dieser kernkondensierten Alkylnaphthalinsulfonate derjenigen der einfachen Produkte deutlich überlegen ist. Man kann diese Emulgatoren auch mit Erfolg in Verbindung mit anderen kapillaraktiven Substanzen, wie z. B. den Fettalkoholsulfonaten, den oleylaminoäthansulfonsauren Salzen oder den Verseifungsprodukten von sulfochlorierten Kohlenwasserstoffen, verwenden.It has now been shown that one can easily do without using Such additives can be used as emulsifiers in place of the simple alkylated aromatic or hydroaromatic sulfonic acid products used by condensation with core condensing agents such. B. formaldehyde, Acetaldehyde, chlorosulfur, etc., made from the sulfonic acids mentioned will can (see patent specification 445 588). It has proven to be useful to do so To use condensation products in their preparation to 2 moles of sulfonic acid less than 1 mole of formaldehyde, up to 1/2 mole and less, are used. When using the condensation products used according to the invention, one has once the advantage that, even when using chlorinated cresols, the resulting with calcareous Water obtained thin usable solutions except for an insignificant opalescence stay blank. In addition, it has been shown that the emulsifiability of these core-condensed alkylnaphthalene sulfonates of those of the simple products is clearly superior. One can also use these emulsifiers in conjunction with success with other capillary-active substances, such as. B. the fatty alcohol sulfonates, the oleylaminoethanesulfonic acid salts or the saponification products of sulfochlorinated Hydrocarbons.

Beispiel Man behandelt i kg rohe Isopropylnaphthalinsulfonsäure, wie sie sich bei der gemeinsamen Behandlung von Isopropylalkohol und Naphthalin mittels Schwefelsäure bildet, mit 15o Teilen io°/oigem Formaldehyd bei Temperaturen von 4o bis 50°, bis der Geruch nach Aldehyd verschwunden ist. Hierauf führt man das Kondensationsprodukt in üblicher Weise in das Natriumsalz über.Example 1 kg of crude isopropylnaphthalenesulfonic acid is treated as they differ in the joint treatment of isopropyl alcohol and naphthalene means Forms sulfuric acid, with 150 parts of 10% formaldehyde at temperatures of 40 to 50 °, until the smell of aldehyde has disappeared. This is what one leads to Condensation product in the usual way into the sodium salt.

7 Teile p-Chlormetakresol und 3 Teile symm. Chlorxylenol werden mit Hilfe von 7o Teilen einer 5oo/oigen Lösung des oben beschriebenen, mittels Formaldehyd kernkondensierten isopropylnaphthalinsulfonsauren Natriums sowie 6 Teilen Isopropylalkoholund 12 Teilen Wasser unter Erwärmen gelöst. Das erhaltene Präparat gibt auch in verdünnten Lösungen mit Berliner Leitungswasser blanke bzw. nur schwach opaleszierende Lösungen, ohne daß Ausscheidungen auftreten. Stellt man 2°/oige wäßrige Lösungen aus dem oben beschriebenen Konzentrat her, so kristallisieren auch in der Kälte die Chlorkresole nicht aus.7 parts p-chlorometacresol and 3 parts symm. Chlorxylenol are using With the help of 70 parts of a 500% solution of the one described above, using formaldehyde nuclear-condensed sodium isopropylnaphthalenesulfonic acid and 6 parts of isopropyl alcohol 12 parts of water dissolved with heating. The preparation obtained is also available in diluted form Solutions with Berlin tap water are bright or only slightly opalescent solutions, without excretions occurring. If you put 2% aqueous solutions from the above concentrate described, the chlorocresols also crystallize in the cold not from.
