    摘要: 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 or halogen, are prepared by a process in which a pyrazole of the general formula II ##STR2## where R.sup.1, R.sup.2 and R.sup.3 have the meanings stated for formula I, is reacted with an aliphatic or aromatic peroxocarboxylic acid, preferably in the presence of from 0 to 15 moles of an alkali metal hydroxide, alkaline earth metal hydroxide, alkali meteal carbonate or alkaline earth metal carbonate in such a way that the reaction temperature is from -5.degree. C. to 60.degree.C.The reaction can be carried out in water as a solvent or in a 2-phase system consisting of water and an inert organic solvent which is poorly miscible with water, in the presence or absence of a suitable phase transfer catalyst. The peroxocarboxylic acid can be prepared in the reaction mixture before the reaction from H.sub.2 O.sub.2 and an acyl halide or a carboxylic anhydride or can be used in the form of an alkali metal salt or alkaline earth metal salt.

    摘要: Cured aminoplast resins are recycled by a process in which said resins, which may contain fillers, are treated with an aqueous sulfite, hydrogen sulfite or disulfite solution and the resulting low molecular weight degradation products are used in chemical processes. The resulting low molecular weight degradation products of cured aminoplast resins are used for coating moldings, for tanning leather and skins and for the production of moldings which contain cured aminoplast resins or consist thereof.

    摘要: A transparent pigmentary form of 4,4',7,7'-tetrachlorothioindigo is prepared by oxidizing the leuco compound of tetrachlorothioindigo in aqueous alkaline suspension, in the presence of a dithionite, at from 20.degree. to 100.degree. C., with simultaneous exposure to shearing forces. Preferably, the oxidation is carried out in the presence of a surfactant.The pigment obtained gives brilliant, transparent full-shade colorations, while white reductions have a deep pure reddish hue.
