TECHNIQUE OF PREPARING MODIFIED SILICA FROM OIL SHALE RESIDUE; pp. 309–320

The raw material – residue of oil production from Huadian oil shale – was modified with cationic surfactants; the hydroxyl groups on the aggregated silica surface were alkylated directly. The structure of alkylated Si-hydroxyl on modified silica surface was characterized by means of infrared spectro...
