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: 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.
