The present invention is based on a process for oligothiophene synthesis at elevated temperatures and low catalyst concentrations.

Method for the production of thiophene oligomers

Process for industrial scale synthesis of poly- and oligothiophenes, which works in concentrated solution. In this process, a solution which comprises an organometallic thiophene reagent is added to a second solution which comprises a catalyst.

Process for the preparation of poly- and oligothiophenes on an industrial scale

The invention relates to a process for producing morphologically uniform and virtually monodisperse metal-containing nanoparticles, characterized in that the separation both in time and space of the nucleation and growth processes is achieved by regulation of the temperature and volume flows, with the reaction and particle formation preferably being initiated and carried out in a suitable microstructured modular reactor system. Modularization of the microreaction plant (micro heat exchanger, residence reactor, micromixer, etc.) allows optimal setting of the respective chemical and process-engineering process parameters and thus the preparation of virtually monodisperse and morphologically uniform nanoparticles.

Process for the synthesis of nanosize metal-containing nanoparticles and nanoparticle dispersions
