1.What is the MOLECULAR SIEVES ?
white powder
Porous crystallinesubstances, especially aluminosilicates(see zeolite), that can be dehydratedwith little change in crystalstructure. As they form regularlyspaced cavities, they provide a highsurface area for the adsorption ofsmaller molecules. The general formula of these substancesis MnO.Al2O3.xSiO2.yH2O,where M is a metal ion and n is twicethe reciprocal of its valency. Molecularsieves are used as drying agentsand in the separation and purificationof fluids. They can also be loadedwith chemical substances, which remainseparated from any reactionthat is taking place around them,until they are released by heating orby displacement with a morestrongly adsorbed substance. Theycan thus be used as cation exchangemediums and as catalysts and catalystsupports. They are also used asthe stationary phase in certain typesof chromatography (molecular-sievechromatography).
Molecular sieves are porous crystalline substances, particularly aluminosilicates, that can be dehydrated with little change in crystal structure. They form regularly spaced cavities, providing a high surface area for the adsorption of smaller molecules. These crystalline metal aluminosilicates have a 3-dimensional interconnecting network of silica and alumina tetrahedra, with uniform cavities that selectively adsorb molecules of a specific size. Molecular sieves are used as drying agents and in the separation and purification of fluids, as well as cation exchange mediums, catalysts, and catalyst supports.
2.What is the CAS number for MOLECULAR SIEVES ?
The CAS number of MOLECULAR SIEVES is 308080-99-1.
