The present invention relates to a process for preparing a macrocyclic diketone compound of the formula (I), which comprises the oxidation of a bicycloolefine compound of the formula (II) with an oxidizing agent, formulae (I) (II) where in formulae (I) and (II) A is (CH)with n being an integer from 2 to 12, where two hydrogen atoms may be replaced by C-C-alkyl, in particular methyl, or two hydrogen atoms, which are bound to adjacent carbon atoms may be replaced by a fused 5- or 6-membered saturated carbocycle; B is (CH)with m being 1 or 2, where 1 or 2 hydrogen atoms may be replaced by C-C-alkyl, in particular methyl. 

Process for preparing a macrocyclic diketone

A process for producing pellets comprising biologically active substances in which the biologically active substances are homogeneously dispersed in a matrix based on at least one thermoplastic polymer, which polymer has in aqueous medium a pH-dependent solubility, by homogeneous mixing of the starting materials in the melt and subsequent extrusion and shaping, which comprises the shaping being performed in a cooling medium in which the pellets are not soluble or dispersible.

Underwater or under-hydrocarbon pelletizing of biologically-active-compound-containing melts

Retarding formulations of active substances used for plant protection

Solid dosage forms are obtained by mixing at least one polymeric binder, at least one active ingredient, and, where appropriate, conventional additives to form a plastic mixture, and shaping, using as polymeric binder a copolymer of an N-vinyllactam and a copolymerizable monomer having a hydrophobic radical. Dosage forms which show slow release of the active ingredient are obtained in a simple and low-cost manner.

Styrene-containing popcorn polymers, method for producing same and utilisation

A process for preparing liquid iodophores with poly-N-vinyllactams and dextrins as carrier materials, which comprises heating a mixture of the carrier materials, iodine and iodide ions or, in place of the iodide ions, a reducing agent in aqueous medium in the presence of a monohydric or polyhydric alcohol having 1 to 6 carbon atoms at from 40 to 100&deg; C.
