Silica gel Usage And Synthesis

Chemical Properties	white to off-white powder
Chemical Properties	Amorphous silica, the noncrystalline form of SiO2, is a transparent to gray, odorless, amorphous powder
Uses	Silica gel was used on glass plates for preparative TLC and on aluminium sheets for analytical TLC. Silica gel was used in vacuum chromatography and TLC. Silica gel was used in column chromatography.
Definition	A gel made by coagulating sodium silicate sol. The gel is dried by heatheating and used as a catalyst support and as a drying agent. The silica gel used in desiccators and in packaging to remove moisture is often colored with a cobalt salt to indicate whether it is still active (blue=dry; pink=moist).
Definition	A rigid gel made by coagulatinga sol of sodium silicate andheating to drive off water. It is usedas a support for catalysts and also asa drying agent because it readily absorbsmoisture from the air. The gelitself is colourless but, when used indesiccators, etc., a blue cobalt salt isadded. As moisture is taken up, thesalt turns pink, indicating that thegel needs to be regenerated (by heating).
Agricultural Uses	A hard granular hygroscopic form of hydrated silica is called silica gel. It is made by heating a coagulated sol of sodium silicate. It is used as a catalyst and a desiccant.
Potential Exposure	Amorphous fumed silica is used as a mineral, natural or synthetic fiber. A potential danger to those involved in the production and handling of fumed silica for paint pigments or catalysts. Diatomaceous earth is used in clarifying liquids, in manufacture of fire brick and heat insulators; used as a filtering agent; as a filler in construction materials; pesticides, paints, and varnishes. A potential danger to those involved in mining of diatomaceous earth or fabrication of products there from.
Purification Methods	Before use as a drying agent, silica gel is heated in an oven, then cooled in a desiccator. Conditions in the literature range from heating at 110o for 15hours to 250o for 2-3hours. Silica gel has been purified by washing with hot acid (in one case successively with aqua regia, conc HNO3, then conc HCl; in another case it was digested overnight with hot conc H2SO4), followed by exhaustive washing with distilled water (one week in a Soxhlet apparatus has also been used), and prolonged oven drying. Alternatively, silica gel has been extracted with acetone until all soluble material was removed, then dried in a current of air, washed with distilled water and oven dried. Silica gel has also been washed successively with water, M HCl, water, and acetone, then activated at 110o for 15hours. Silicon monoxide [10097 -28 -6] M 44.1, m > 1700o, d 4 2.18. Purify the monoxide by sublimation in a porcelain tube in a furnace at 1250o (4hours) in a high vacuum (10-4mm) in a stream of N2. It is obtained as brownish black scales. [Schenk in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 696 1963.]
Incompatibilities	Silica, amorphous is a noncombustible solid. Generally unreactive chemically. Incompatible with fluorine, oxygen difluoride, chlorine trifluoride. Soluble in molten alkalis and reacts with most metallic oxides at high temperature.
Waste Disposal	Sanitary landfill.
