摘要:
The present invention relates to a process for preparing mono-N-sulphonylated diamines by reacting diamines with sulphonyl halides in the presence of water, base and organic solvents.
摘要:
Processes comprising: providing a catalyst comprising a catalytic component selected from the group consisting of ruthenium, ruthenium compounds, and combinations thereof, wherein the catalyst is sulfur-poisoned with one or more sulfur compounds; and treating the catalyst with a gas stream comprising a hydrogen halide under nonoxidative conditions such that the catalyst is regenerated.
摘要:
The present invention relates to a process for the preparation of chlorine by gas phase oxidation using a supported catalyst based on ruthenium, characterised in that the catalyst support has a plurality of pores having a pore diameter>50 nm and carries nanoparticles containing ruthenium and/or ruthenium compounds as catalytically active components.

摘要:
The present invention relates to a process for mobilizing metallic ruthenium or ruthenium compounds from solids to form volatile ruthenium compounds by means of a gas stream containing a hydrogen halide and carbon monoxide, preferably hydrogen chloride and carbon monoxide, and for isolating the previously mobilized ruthenium compounds, preferably by deposition with cooling, e.g. in relatively cold zones, in particular on relatively cold surfaces, absorption in suitable solutions or adsorption on suitable support materials.
