Abstract:
A process for the hydrogenation of imines with hydrogen under elevated pressure in the presence of iridium catalysts containing diphosphine ligands, with or without an inert solvent, the reaction mixture containing a soluble ammonium chloride, bromide or iodide or a soluble metal chloride, bromide or iodide, wherein the reaction mixture additionally contains at least one solid acid with the exception of ion exchangers. Improved optical yields and high chemical conversion rates are achieved while the catalyst is easily separable.
Abstract:
A flow cell (1) has in its interior a flow channel (2) and is provided with an inlet opening (3) for the sample and with an outlet opening (4). Also provided are means for producing a sample-free blocked volume located in the flow channel (2). Those means comprise, for example, a further inlet opening (5) for a reference fluid, that inlet opening (5) being so positioned that the reference fluid flows counter to the sample in the flow channel (2). The flow cell (1) is suitable for a sensor apparatus in which one of the boundary surfaces of the flow channel (2) comprises a detection layer that contains selectively sensitive recognition elements for an analyte. The flow cell (1) is also suitable for an optical detection device which preferably utilises luminescence excitation in the evanescent field of an optical waveguide.

They can be used on their own or as formulated compositions, preferably for controlling or preventing infestation with microorganisms.
Abstract:
Compositions and methods for reducing the decomposition rate of polymeric bioadhesives and viscosity enhancers, such as poly(acrylic acids). The compositions include at least one strong, stable chelating agent, preferably an organophosphorous compound such as diethylene triamine penta(methylene phosphonic acid). These biocompatible compositions are especially useful in the ophthalmic field.
Abstract:
Described is a process for the production of a library from a plurality of different units consisting of a solid or semisolid carrier (bead), a synthetic ligand and a binary information structure (tag), by means of which the building blocks of the ligand are coded, and the use of that library for searching for novel classes of active ingredient and individual active ingredients. Also described are compounds found using that process. The process is characterized by the use of element atoms or ions as binary tags which are bound non covalently to the beads. Their unique combination which can be measured by e.g. mass spectrometry codes for the specific ligand.
