Abstract:
Methodologies for the synthesis, screening and characterisation of organometallic compounds and catalysts (eg homogenous catalysts), including combinatorial synthesis, screening and characterisation of libraries of supported and unsupported organometallic compounds and catalysts (eg homogenous catalysts). The methods can be applied to the preparation and screening of large numbers of organometallic compounds which can be used not only as catalysts (eg homogeneous catalysts), but also as additives and therapeutic agents.

Abstract:
An apparatus for use in parallel reaction of materials. The apparatus includes a base (32) having a plurality of reaction wells, each of the reaction wells (30) having a closed lower end (84) and open upper end for receiving reactant materials. A cover (34) is configured for sealing engagement with the base to form a housing enclosing the plurality of reaction wells and defining a common pressure chamber (26) in communication with the reaction wells. The apparatus further includes a flow restriction device (92) positioned adjacent to the open ends of the reaction wells to provide communication between the reaction wells and the pressure chamber while reducing cross-talk between the reactants and an inlet port (70) in communication with the pressure chamber for supplying pressurized fluid to the chamber to pressurize the reaction wells. The housing is configured to sustain a pressure substantially above atmospheric pressure.
Abstract:
An apparatus and method for carrying out and monitoring the progress and properties of multiple reactions is disclosed. The method and apparatus are especially useful for synthesizing, screening, and characterizing combinatorial libraries, but also offer significant advantages over conventional experimental reactors as well. The apparatus generally includes multiple vessels for containing reaction mixtures, and systems for controlling the stirring rate and temperature of individual reaction mixtures or groups of reaction mixtures. In addition, the apparatus may include provisions for independently controlling pressure in each vessel, and a system for injecting liquids into the vessels at a pressure different than ambient pressure. In situ monitoring of individual reaction mixtures provides feedback for process controllers, and also provides data for determining reaction rates, product yields, and various properties of the reaction products, including viscosity and molecular weight.
