    Abstract: It is described a method for producing 1-substituted 5- and/or 3-hydroxypyrazoles of formulas (I) and (II), wherein R1 represents C1-C6-alkyl, C2-C6-alkenyl, C2-C6-alkinyl, C3-C6-cycloalkyl or C1-C4-alkoxy, whereby these groups can be substituted by halogen, C1-C4-alkoxy, phenoxy, C1-C6-alkoxycarbonyl, C1-C6-alkylthiocarbonyl or a cyclic ring system with 3-14 ring atoms, by reacting a 3-alkoxyacrylic acid alkyl ester of formula (III), wherein R2, R3 independently mean C1-C6-alkyl or C3-C6-cycloalky, with a hydrazine of formula (IV), wherein R1 has the above cited meaning, a) at a pH value of 6-11 to form 5-hydroxypyrazoles of formula (I), or b) at a pH value of 11-14 to form 3-hydroxypyrazoles of formula (II).

    Abstract: The present application relates to the use of formulations comprising a) at least one polymer as component A comprising at least one structural unit of the formula (I) where the structural unit may be part of a polymer main chain or may be bonded to a polymer main chain via an anchor group, and M is hydrogen or a metal cation; and water; for the treatment of hard surfaces as compositions for improving the run-off behavior of water from the treated hard surfaces and for reducing soil and salt deposition on the treated hard surfaces, and to formulations for the treatment of hard surfaces comprising the at least one polymer, at least one surfactant and at least one carboxylic acid and/or sulfonic acid and/or inorganic acid, and to the use of these formulations for the treatment of hard surfaces.

    Abstract: New copolymerisable containing 0.01-1 weight percent of aceto- or benzophenone derivatives in polymerized form. New copolymerisable containing 0.01-1 weight percent of aceto- or benzophenone derivatives in polymerized form. The derivatives have the formula (I). R = optionally substituted 1-3C alkyl, 6-10C aryl, or aralkyl with 6-10C in the aryl part and 1-6C in the alkyl part. Independent claim are also included for: (1) a process for the preparation of the copolymerisable by polymerization of a mixture of ethylenically unsaturated compounds (monomers) containing 0.01-10 weight percent (wt.%) of aceto- or benzophenone derivatives of formula (I); and (2) use of the copolymerisable as a copolymerizable photoinitiator.

    Abstract: Process for distillatively separating a mixture containing a vinyl ether of the general formula (I) R1—O—CH═CH2  (I) and alcohol of the general formula (II) R2—OH  (II) in which R1 and R2 are each independently a saturated or unsaturated, aliphatic or cycloaliphatic radical having from 2 to 10 carbon atoms, and in which the alcohol (II) has a boiling point which is at least 1° C. higher, measured at or extrapolated to 0.1 MPa abs, than the vinyl ether (I), by a) passing the mixture into a first distillation column and withdrawing, as a top product, an azeotrope containing vinyl ether (I) and alcohol (II) and, as a bottom product, a stream enriched with the alcohol (II); b) passing the azeotrope containing vinyl ether (I) and alcohol (II) from the first distillation column into a second distillation column which is operated at a pressure which is from 0.01 to 3 MPa higher compared to the first distillation column, and withdrawing, as a bottom product or gaseous sidestream in the stripping section, the vinyl ether (I) and, as a top product, an azeotrope containing vinyl ether (I) and alcohol (II); and c) recycling the azeotrope containing vinyl ether (I) and alcohol (II) from the second distillation column into the first distillation column.
