General description

Sand, generally known as silicon dioxide, is used as a precursor, filler, and additive or processing aid in plastics, synthetic rubbers, catalyst carriers, chemical sensors, adhesives, pesticides, paper, paints, coatings, sealants, or insulation materials.

Application

Sand and granite can be employed as a catalyst in the three-component condensation of aldehydes, 1,3-dicarbonyl compounds, and ureas or thioureas to produce 3,4-dihydropyrimidinones and 3,4-dihydropyrimidinthiones.
Suitable for chromatography
