Anwendungen & Verwendung
Verwenden
Trimethylsilyl chlorosulfonate may be used:in the sulfonation of small organic molecules in the synthesis of sulfonated polysulfone as sulfonating agent in the preparation of nano-structured organic-inorganic membranes for proton exchange membrane fuel cells (PEMFC) based on methacrylate and epoxy polymeric structures in the preparation of sulfonated polysulfone (sPS)/titanium dioxide (TiO2) composite membranes for use in PEMFCs in the preparation of iodosobenzene sulfate, required for the synthesis of cyclic sulfates
