Process for the preparation of an aqueous colloidal precious metal suspension, for the production of a supported precious metal catalyst and for the production of 3-hexenol.

摘要

The invention is directed to a process for the preparation of an aqueous colloidal precious metal suspension, which process comprises reducing a precious metal salt in aqueous solution using a functionalised, water soluble quaternary ammonium salt in the absence of organic solvents, to form elementary nanoparticles.
