Significance

Reported is an efficient method to synthesize octacarboxy spherosilicate, OCPDS. It was converted from ODMPS by bromination and then hydrolysis in the presence of AgNO3 and formic acid. The structure of ODMPS and OCPDS were both confirmed by FT-IR, ¹H NMR, ¹³C NMR, ²9Si NMR, ESI-MS, and elemental analysis.
