    Abstract: Finely divided, pulverulent carotinoid or retinoid compositions, in which the carotinoid or retinoid essentially has a particle size of less than 0.5 micron, are prepared by a process wherein a carotinoid or retinoid is dissolved in a volatile, water-miscible, organic solvent at from 50 DEG C. to 200 DEG C., if necessary under superatmospheric pressure, within the space of less than 10 seconds. The carotinoid is immediately precipitated, in a colloidally disperse form, from the molecularly disperse solution by rapidly mixing the latter with an aqueous solution of a swellable colloid at from 0 DEG C. to 50 DEG C., and the resulting dispersion is freed from the solvent and the dispersing medium in a conventional manner.

    Abstract: The invention relates to a solid crop protection formulation comprising a) at least one crop protection agent selected from the group consisting of herbicides, pesticides and fungicides, with the proviso that cinidon-ethyl is not included; b) at least one random radical copolymer comprising as polymerized units at least one hydrophilic and at least one hydrophobic monomer; and c) optionally further additives, wherein at least 50% of the dispersed particles of the at least one crop protection agent in said solid crop protection formulation are in X-ray amorphous state. Additionally, the invention relates to processes for preparing said formulations and the use of said formulations in agriculture.

    Abstract: Preparation of stable fine particle powders comprises: (a) dissolving one or more substances (A) and one or more substances (B) in a super-critical, compressible fluid; and (b) relaxing the fluid along a residence path, where the solubility limit of (A) is earlier than that of (B) in the residence path. An Independent claim is included for an apparatus for carrying out the process comprising a first high pressure autoclave (2) for dissolving substance (A) in a super critical fluid and a second high pressure autoclave for dissolving substance (B) in a super critical fluid. Two separate feeds (3, 7) connected to relaxation devices (4, 8) relax both fluids so that their flows intersect.

    Abstract: The present invention relates to a method of and a device for optimizing at least one coating material at at least one point of a substrate surface to which the coating material is applied. The method, which is carried out with the corresponding device, comprises at least the following steps: a) applying said at least one coating material to said at least one point of the substrate surface, b) curing said at least one coating material at said at least one point of the substrate surface, and c) determining the state, especially the curing and/or yellowing and/or gloss, of said coating material at said at least one point of the substrate surface, possessed by said coating material as a consequence of steps a) and b).
