Chemical Properties

White crystal

Definition

ChEBI: An organosilanol in which silicon is bonded to a single hydroxy function and to three phenyl groups.

Purification Methods

It is purified by dissolving in pet ether, passing through an Al2O3 column, eluting thoroughly with CCl4 to remove impurities and then eluting the silanol with MeOH. Evaporation gives crystals with m 153-155o. It can be recrystallised from pet ether, CCl4 or from *benzene or Et2O/pet ether (1:1). It has also been recrystallised by partial freezing from the melt to constant melting point.
