Description

Protecting goods against moths and similar animal pests It was found; that one to. Protecting goods such as wool, leather, textiles, Fur, hair, feathers, natural or artificial fibers, paper or such Products and compounds containing substances, against moths and similar animal pests can use such aromatic oxy compounds, which are based on each hydroxyl group aromatic radical contain at least one cycloaliphatic radical. Such connections are in particular the phenols, cresols, xylenols, guaiacols. Oxydiphenyls, oxydiphenylmethanes and naphthols, which are common to each hydroxyl-containing aromatic. Rest through at least -a hydroaromatic radical or by at least one hydroaromatic Radical containing group are substituted.

Cycloalkyl radicals are understood to mean radicals such as. B. the cyclohexyl radical, the methylcyclohexyl radical, the sec-butylcyclohexyl radical, the sec-octylcyclohexyl radical, the decylcyclohexyl radical, the cyclohexylcyclohexyl radical, the hexahydrobenzylcyclohexyl radical, the decahydronaphthyl radical or naphthenyl radical (residues of naphthenic alcohols).

These compounds are readily available e.g. B. by condensation of all kinds of cycloolefins, also of monovalent or polyvalent cycloaliphatic ones Alcohols with any aromatic oxy compound. You can z. B. the the above Use cycloaliphatic alcohols corresponding to cycloalkyl radicals for condensation. -U. a. you can use aromatic oxy compounds to use substances such as cyclohexanol, cyclohexene, Methylcyclohexano !, methylcyclohexene, amylcyclohexanol, amylcyclohexene, octylcyclohexanol, Octylcyclohexene, cyclohexylcyclohexanol, cyclohexylcyclohexene, perhydromenaphthylmethylcyclohexanol, dodecahydro-4, 4'-dioxydiphenylmethane or the corresponding olefins, _ condense and the condensation products individually or use as mixtures according to the invention.- -The condensation can with the participation of known condensing agents, of which superchloric acid in particular has proven successful in the form of their aqueous solution.

The compounds mentioned can also carry further substituents. 'In particular, they can also be replaced by one or more halogen, oxo, oxy, alkyloxy or alkyl groups. So can; u. a. also cycloalkyloxyaryl ketones be used.

Suitable compounds are, for example, i. Cyclohexylresorcinol, a. 4-methylcyclohexylphenol, 3 .. 4-cyclohexenylphenol (cf. C. 1929, 11, 1 663), 4. cyclohexyloxyphenyl ketone, 5. sec.-octylcyclohexylphenol, 6. 4- (4'-decahydromenaphthylcyclohexyl) -cr esol. . Those compounds have proven to be particularly valuable which also contain halogenates, such as chlorine atoms, in the aromatic radical, preferably in the p-position to the hydroxyl group. Such connections are z. B. -7. 4-Clilor-2-isoami-lcycloliex, # l @ henz) 1. B., l-Cliloi - 2-liexahydrobenzoylphenol, g. Bis (z-oxy-3-cyclohexyl-5-chlorophenyl) methane.

ok Bis - (4- (- ';% xy -;' -: h: orphe_iyl) - cyclohexylj-methane.

In place of the free hydroxyl compounds, their etherified ones can also be used or use esterified derivatives. The ethereal residues can be aliphatic: shear. be cycloaliphatic, aromatic in nature. In particular, the methyl, Use ethyl, propyl, allyl, benzyl and phenyl ethers. The ethers can be in per se. in a known manner by reacting the corresponding halogen compounds obtained with aromatic oxides in an alkaline medium.

Usable esters are obtained, for example, by treating the appropriate esters Aromatic oxy compounds in a manner known per se with acids or their derivatives, such as anhydrides and halides. Usable esters are e.g. B. the esters of acetic acid, Chloroacetic acid. Propionic acid, lactic acid, buttic acid. B, nzoic acid, salicylic acid c or cinnamic acid.

The compounds can, as already mentioned, by groups of the most varied Kind of substituted. Such groups are also aryl radicals, mercapto and amino groups or their derivatives, such as ester. Amide, sulfide or sulfone groups. Furthermore you can water-solubilizing groups, such as carboxyl groups, sulfonic acid groups. Sulfuric ester groups, qua: additional ammonium groups, polyoxy and / or polyether groups in the molecule enter.

The compounds can be used alone or in admixture with one another as well possibly with the addition of other protective agents in a known manner in dissolved, emulsified or dry form can be used. Has proven to be particularly valuable it proved that the compounds described are odorless or weakly odorous and for the most part are readily soluble in gasoline. One can therefore with the help of the gasoline solutions make the goods moth-proof in a particularly simple way by simply soaking them.

Because of the ease of implementation, the treatment can not only in the manufacture and processing of the goods, but both in the household as well in cleaning facilities, e.g. B. chemical laundries, in the gasoline laundry or washing with other, especially non-flammable organic solvents Take place: It has already been suggested that aromatic oxy compounds also by low molecular weight alkyl radicals and optionally also by halogen atoms Can be substituted as a moth repellent for wool, furs, feathers, hair and the like to be used. The connections mentioned in the older literature are liable however, the disadvantage that they have no solubility in gasoline, but only can be made soluble in it with the help of other substances and consequently not used in the usual petrol washing of textile goods etc. in dry cleaning can be.
