N-hydroxypyrazoles of the general formula I ##STR1## where R.sup.1, R.sup.2 and R.sup.3 may be identical or different and are each hydrogen, alkyl, halogen or aryl, or R.sup.1 and R.sup.2 or R.sup.2 and R.sup.3 together with the carbon atoms carrying these radicals form an aromatic or nonaromatic ring of 5 or 6 carbon atoms are prepared by a process in which(A) a pyrazole of the general formula II ##STR2## is converted in a conventional manner with an alkali metal hydroxide, alkali metal hydride or alkali metal carbonate into one of its metal salts of the general formula III ##STR3## where ME.sym. is a cation of an alkali metal, and (B) the resulting metal salt of the general formula III is reacted with dibenzoyl peroxide in an inert organic solvent or in a 2-phase system, in the presence or absence of a phase transfer catalyst.

摘要:
The preparation of 1-hydroxyimidazoles of the formula I ##STR1## where the R radicals can be identical or different and are each halogen or an organic radical, it also being possible for vicinal radicals to be connected to form an aromatic or nonaromatic ring of from 3 to 12 carbon atoms, and n is from 0 to 3, entails reacting an imidazole of the formula II ##STR2## where Q is preferably hydrogen or, especially where R is not halogen, an alkali metal or alkaline earth metal cation, with an organic peroxide.The products are valuable intermediates for organic syntheses.
摘要:
4-Chloropyrazoles of the general formula I ##STR1## where R.sup.1, R.sup.2 and R.sup.3 are each independently of the others hydrogen or a radical which is inert under the reaction conditions, are prepared by reacting pyrazoles of the general formula II ##STR2## wherein R.sup.1, R.sup.2 and R.sup.3 are each as defined above, with 0.95-10 equivalents of hypochloric acid, or salts thereof, in the substantial absence of any carboxylic acid.

摘要:
A process for dyeing and printing textile materials consisting of cellulose fibers or containing cellulose fibers in a blend with other fibers in an aqueous medium at above pH 12 with vattable dyes in the presence of cyclic compounds which contain at least one instance of the structural unit ##STR1## in the ring of the molecule as reducing agents and finishing the dyeing in a conventional manner.
摘要:
The present invention relates to a method for cleaning surfaces using an aqueous composition comprising at least one hydrophobin and a synergistically effective, non-interface-active, water-soluble additive. The method is suitable in particular for cleaning hard, hydrophobic, poorly wettable surfaces, such as, e.g., plastic floors.
