Abstract: There are described liquid microbicidal agents containing compounds from the series comprising o-phenylphenol, p-chloro-m-cresol, p-chloro-m-xylenol and pentachlorophenol and not more than 50 percent by weight of an organic solvent or solvent mixture, and their preparation and use.

Abstract: The invention relates to the use of water-soluble polymers containing chemically bonded tertiary and/or quaternary ammonium groups as auxiliaries for formulating microbicides, the microbicide formulations prepared using these water-soluble polymers and the use of these formulations for preserving industrial materials.

Abstract: Fibers and filaments of synthetic polymers containing from 0.1 to 5%, by weight, based on polymer, of an azole compound corresponding to the following general formula: ##STR1## and from 0.1 to 5%, by weight, based on polymer, of a dihydroxydiphenylmethane derivative corresponding to the following general formula: ##STR2## wherein n represents 0 or 1;m represents 0, 1 or 2;R.sub.1 represents halogen, halophenyl or phenyl;R.sub.2 represents --CO--C(CH.sub.3).sub.3 or --CHOH--C(CH.sub.3).sub.3 ; andR.sub.3 and R.sub.4 represent halogen,show laundry-stable, antimicrobial activity.

Abstract: Threads and fibres of synthetic polymers containing from 0.1 to 5% by weight, based on the polymer, of one or more than one compound corresponding to the formula (I) ##STR1## wherein R represents hydrogen or alkyl,R.sup.1 represents halogen, hydroxyl, optionally substituted alkyl, optionally substituted alkoxy, optionally substituted phenoxy, a group --S(O).sub.p -alkyl which is optionally substituted in the alkyl portion, nitro, optionally substituted amino or a condensed carbocyclic or heterocyclic group,p stands for the numerical value 0, 1 or 2,R.sup.2 represents halogen, alkyl which is optionally substituted, alkoxy, alkylmercapto, nitro, cyano, carboxylic acid amide or a condensed carbocyclic group,m represents an integer from 0 to 5,n represents an integer from 0 to 4, the substituents being either identical or different when m and/or n has a value greater than 1, and X, Y and Z are identical or different and represent a nitrogen atom, the group .dbd.CH-- or ##STR2## where R.sup.

Abstract: The present invention relates to iodopropargyl-ammonium salts of the formula (I) ##STR1## in which R, R.sup.1, R.sup.2 and X.sup..phi. have the meanings given in the description.They are obtained, for example, by reacting tertiary amines with an iodopropargyl halide. In a second reaction step, the halogen anion can be exchanged for other anions, such as phosphate and sulphate. The iodopropargylammonium salts of the formula (I) are distinguished by high activity as pest-combating agents, in particular by a fungicidal as well as bactericidal activity.

Abstract: The preparation of a 2-halogeno-3-sulphonyl acrylonitrile from a 2,2-dihalogeno-3-sulphonyl propionitrile and water and the use of the product as a microbicidal agent are disclosed.

Abstract: Preventing corrosion and scale formation in water re-circulating systems by adding to the water to be circulated from about 5 to 100 g/m.sup.3, based on the weight of the water to be circulated, of a compound selected from the group consisting of those of the formula ##STR1## and the water-soluble salts thereof and then circulating said water in said system, R being hydrogen, alkyl, alkenyl or alkinyl having up to 4 carbon atoms; phenyl; cycloalkyl having 3 to 6 carbon atoms; benzyl; phenethyl or ##STR2## wherein R' is hydrogen, alkyl having 1 to 4 carbon atoms or carboxyl, R" is hydrogen or methyl and R'" is carboxyl.

Abstract: Certain novel .alpha.-alkyl-phosphonosuccinic acid compounds of the formula ##STR1## in which R is lower alkyl, or alkenyl or alkynyl, cycloalkyl, or aralkyl are particularly suitable as sequestering agents, e.g., for incorporation into cleansing compositions.

Abstract: Preventing corrosion and scale formation in water re-circulating systems by adding to each cubic meter of the water being re-circulated from about 5 to 100 grams of a compound selected from the group consisting of those of the formula ##EQU1## and the water-soluble salts thereof R being hydrogen, alkyl, alkenyl or alkinyl having up to 4 carbon atoms; phenyl; cycloalkyl having 3 to 6 carbon atoms; benzyl; phenethyl or ##EQU2## wherein R' is hydrogen, alkyl having 1 to 4 carbon atoms or carboxyl, R" is hydrogen or methyl and R'" is carboxyl.
