Description

239595 3

BACKGROUND OF THE INVENTION The present invention relates to a practically odorless, yet petrochemical composition, of a readily available, effective disinfectant or disintegrant component of disinfectants, detergents, preservatives, impregnating agents, paints, and the like, mainly with significant bactericidal, fungicidal, respectively. antimycotic effects.

Especially effective and harmless odorless disinfection is particularly useful for preventing infectious disease threats and for eradicating infections. It is also important in public and private sanitary facilities, in the use of xylogen, especially on synthetic fibers that cannot be sterilized at high temperatures. under pressure and even as cotton fabrics. Furthermore, for the disinfection of the Department of Hospitals, disinfection of medical equipment and, last but not least, veterinary medicine and livestock production with massive livestock breeding where there is a danger of various epidemics. In addition, for the protection of wood against wood-blocking fungi, odorless, side-effect-free and effective fungicidal agents or impregnating coatings, coatings and the like are suitable.

For this purpose, a number of phenols are used as disinfectants, such as cresols, chlorophenols, tetrachlorophenol and pentachlorophenol, 2-hydroxydiphenyl, benzylphenols, cyclohexylphenols [Spaulding EM: J. Hosp. 9, 5 (1972); Ehrhart G., Rusching H.:Arzneimittel - Entwicklung - Wirkung —— Darstellung, 4 vol, 25-30 Verlag Cheie (1972); čs. patents 150, 889, 152, 180 and 183, 478; Lindner K .: Tenside - Textilhilf-smittel Waschrohstoffe WissenschaftlicheVerlagsgesselschaft MBH - Stuttgart (1971)]. Their disadvantage is either unpleasant odors, side-effects, but their production is necessary for relatively large-scale degrees. A technically relatively easy to obtain, yet effective and practically odorless, and without side-effect is a disinfectant or disinfectant component according to the invention.

SUMMARY OF THE INVENTION The present invention is directed to a disinfectant and / or disinfectant, detergent, preservative, and coating component comprising a phenol derivative and / or an alkali metal phenolate derivative and / or a phenolate ammonium derivative, optionally together with excipients. by activating at least one monoalkylphenol to tetraalkylphenol with alkyls having a carbon number of 6 to 18, preferably in the form of monoalkylphenolate to tetraalkylphenate and / or at least one aryl alkylphenol having a molecular weight of over 276g. mol-1 of the general formula

RR '(C 6 H 2 R ") OX wherein X = H, Na, K, or NH 1; R and R '= H, benzyl, benzylmethyl; R '= H, C4 to C18 alkyl. The advantage of the disintegrating agent and / or the disinfectant component is the relatively high disinfection efficiency, in particular the bacterial and antimycotic activity, and the fact that other products of phenol alkylation and aryl-alkylation of phenol, for which there is a lack of technical properties, can also be used. -economic evaluation. A further advantage is the possibility of simultaneously producing hydrophobic components for non-ionic or anionic surfactants or intermediates for antioxidants, as well as active substances of the disintegrant or disintegration component on one device.

On the one hand, these compounds can be intentionally produced and isolated as by-products from the alkylation of phenol by higher olefins, higher alcohols, alkyl halides or alkyl-tert-butyl ethers, further from arylalkylation of phenol with styrene or methyl phenylcarboline or methylcyclohexylcarbinol. In addition, it can be produced by alkylation of benzylphenol and / or benzylmethylphenol with alkali, alkyl-tert-butyl ethers, alcohols, alkyl chlorides with C1 -C18 alkyls. Particularly suitable for this purpose are octylphenol, nonylphenol, dodecylphenol, tetradecylphenol, hexadecylphenol, octadecylphenol and their dialkyl to tri-alkylphenols. Tetraalkylphenol-containing monoalkylphenols are an important starting material for the production of non-ionic surfactants for the production of alkyl salicylates and also other additives in mineral oils and the like, but may be similar to the by-products dialkylphenols to tetra-alkylphenols, respectively. mono- to tetraalkylphenates with a disinfectant or disinfectant component of disinfectants, detergents, impregnating agents, fungicides, paints. Excipients include ionic and non-ionic surfactants, especially protective colloids, respectively. emulsifiers and dispersants, solvents, fragrances, binders, fillers, thixotropic substances, dyes and pigments.

Disinfectants according to the invention are applied as such or diluted in organic solvents, in particular ethanol, optionally dispersed in water under the action of emulsifiers or dispersants. In the case of the preparation of aqueous solutions, their application is preferably in the form of an alkyl- and / or an- alkaline arylalkylphenates. Such solutions or emulsions, or dispersions, typically have an effective concentration of 0.5 to 5%, but can reach up to tens of percent. While the solubility of the molecules decreases, the solubility of the emulsifiers and / or dispersants makes it possible to prepare the endowed emulsions or effervescent agents even in water. Thus, the active substances are often applied as a component, whether disinfectants, detergents, impregnating oils, impregnating agents, for example against wood-destroying fungi, as a component of paints, for example for timber-building and other timber industry products. -l, during restoration works etc. The disinfectant compositions as well as the disinfectant components of the present invention can also be combined with known other disinfectants or disinfectants.

Their effects as well as other advantages are clear from the examples. Example 1 Commercial nonylphenol is treated with an aqueous solution of sodium hydroxide at a concentration of 10% by weight. with co-activity of 0.2 wt. lauryl polyglycol is prepared in an aqueous solution of sodium nonylphenolate. The concentration of the active ingredient in the aqueous solution is adjusted to 15% by weight. sodium nonylphenolate.

Similarly, an aqueous solution of mixtures of sodium dibenzylmethylphenol, sodium tricresolate and sodium cumylphenate is prepared.

Minimum Inhibitory Concentration (MIC) Values in pg. cm-3 media, are determined by dilution method. The 0-8 active substance is diluted in a series of tubes in 10% DMSO, microorganisms are added (10 9 cells in 1 cm 3 of solution). Disinfectants are allowed to act for 30, 60 and 120 minutes. Then transfer the inoculum (50 μΐ in volume) to tubes with 2 cm3 of test medium. These tubes were cultured for 24 hours in the case of bacteria and 48 hours in the case of yeasts and molds at 37 ° C and then the effect was evaluated. In tubes where growth of microorganisms, color is changed from red to rye. The MIC value is in the tube that remains last unchanged. The results obtained are summarized in Table 1. Example 2

The primary effect of disinfectants, namely tricresol, cumylphenol, nonylphenol with an admixture of 3.5 wt. dinolinylphenols, benzylmethylphenol and mixtures of isomers. dibenzylmethylphenol with an admixture of 1.5 percent by weight tribenzylmethylphenol (all in the form of phenolates in aqueous solution, respectively in emulsion) in a model trial of the growth curves of a sensitive strain of Candida albicans (fungicidal activity, expressed in MIC). So in the case of the MIC 2 50Q. cm-3; in the case of cumylphenol 150; nonylphenol 180; of benzylmethylphenol 125 and a mixture of isomers of dibenzyl methylphenols 125 µg. cm-3. 239595
