Descrizione

General description

Magnesium chloride hexahydrate is a colorless, crystalline solid. On heating, it loses water of crystallization and affords magnesium oxide. It has been tested as a potential phase change material (PCM) for use in cooking indoors and during the low intensity solar radiation periods. Due to its suitable thermo-physical properties, it can be used as storage media in solar cookers. Its flame retardancy action on 100% woven cotton fabric has been investigated. Its heat capacity has been evaluated.

Application

Magnesium chloride hexahydrate may be employed as a catalyst for the synthesis of 3,4-dihydropyrimidin-2-(1H)-one, via Biginelli condensation of aldehyde, 1,3-dicarbonyl compound and urea.
