摘要:
Triazole derivatives of the formula ##STR1## where R denotes benzyl substituted on the phenyl ring by linear or branched alkyl of 1 to 4 carbon atoms, 2-phenylvinyl which is unsubstituted or substituted by halogen on the phenyl ring, 3-phenyl-2-propenyl which is unsubstituted or substituted by halogen on the phenyl ring, 2-phenyl-2-propenyl which is unsubstituted or substituted by halogen on the phenyl ring, 1-phenylethyl, 3-phenylpropyl or 2-phenyl-2-chloroethyl, and salts thereof.Insecticidal agents containing an insecticidal active ingredient selected from the group consisting of carbamates, phosphoric (phosphonic) (di) (thio) acid esters, pyrethrins, pyrethroids, .alpha.-alkylphenyl acetates, .alpha.-cyclopropylphenyl acetates and chlorinated hydrocarbons, and a triazole derivative of the formula I or a salt thereof, have a much stronger insecticidal action than insecticidal agents containing the individual components.
摘要:
Insecticidal agents containing insecticidal active ingredients selected from the group consisting of carbamates, phosphoric (phosphonic) (di)(thio) acid esters, pyrethrins, pyrethroids, .alpha.-alkylphenyl acetates, .alpha.-cyclopropyl-phenyl acetates and chlorinated hydrocarbons, and, to increase the insecticidal action of these active ingredients, triazole derivatives or salts thereof.The triazole derivatives have the formula ##STR1## where R denotes unsubstituted or halogen-substituted phenyl, or ##STR2## Y denoting hydrogen, halogen, alkylmercapto of 1 to 6 carbon atoms, alkenylmercapto of 2 to 6 carbon atoms, or unsubstituted or halogen-substituted phenylmercapto, X denoting halogen, and n denoting one of the integers zero, 1 and 2, with the proviso that n does not denote zero when Y is halogen.
摘要:
N-Cyclohexyl-N-methoxyacetoacetamide, its preparation and its use as an intermediate for the preparation of O-methyl-N-cyclohexyl-2,5-dimethylfuran-3-hydroxamic acid.
摘要:
Paper, board and cardboard are produced from paper stocks which contain tacky impurities by the addition of surfactants and cationic polymers having a charge density of at least 1.5 meq/g (measured at pH 7) and a molar mass Mw of the cationic polymers of at least 15,000 and drainage of the paper stocks with fixation of the tacky impurities in the paper produced.
摘要:
Paper and cardboard are produced by draining pulps, with sheet formation and drying of the sheets, by a process in which first(a) polyethyleneimines having a molar mass M.sub.w of more than 500,000 or polymers containing vinylamine units and having a molar mass of from 5000 to 3 million and then(b) cationic polyacrylamides or polymers containing vinylamine units, the molar masses M.sub.w of the polymers each being at least 4 million,are added to the pulps, and the pulp is then subjected to at least one shearing stage and is flocculated by adding bentonite, colloidal silica or clay.
摘要:
Stable water-in-oil emulsions of a hydrolyzed polymer of an N-vinylamide of the formula ##STR1## where R and R.sup.1 are each H or C.sub.1 -C.sub.6 -alkyl, are prepared by polymerizing a compound of the formula I, alone or as a mixture with other monoethylenically unsaturated monomers, in the form of a water-in-oil emulsion to give a water-in-oil polymer emulsion, and then hydrolyzing the polymer, hydrolysis of the polymer in the form of the water-in-oil polymer emulsion being carried out in the presence of an acid or base, and additives in the form of antioxidants, reducing agents or aldehyde acceptors being added for stabilization.
摘要:
Paper having a high dry strength is made using water-soluble homopolymers of salts or quaternary 1-vinyl-2-imidazolines and copolymers of these salts or quaternary compounds with acrylamide and/or methacrylamide as agents for increasing the dry strength of paper.
