Amorphes Siliciumdioxid

Amorphes Siliciumdioxid

An amorphous silica suitable for use as a stabiliser for alcoholic beverages, eg beers, has a pore volume from about 1.6 to 2.5 cc g , a mean pore diameter from about 8.5 to 14.0 nm and a surface area of at least 450 m g . The silica may be prepared by a precipitation route in which sodium silicate...

Zusammenfassung:An amorphous silica suitable for use as a stabiliser for alcoholic beverages, eg beers, has a pore volume from about 1.6 to 2.5 cc g , a mean pore diameter from about 8.5 to 14.0 nm and a surface area of at least 450 m g . The silica may be prepared by a precipitation route in which sodium silicate is mixed with mineral acid in the presence of electrolyte at a temperature of from 20 DEG C to 50 DEG C.
