Allgemeine Beschreibung
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.
Anwendung
für die Chromatographie
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.
