TRICHLOROGERMANE Chemical Properties,Usage,Production

Chemical Properties

Colorless, mobile liquid. Distills at~75°C. Loses HCl with the formation of GeCl3 at about -30°C. The HCl remains dissolved in the Trichlorogermane(GeHCl3). Therefore GeCl3 can be prepared from GeHCl3 at -30°C (under suction). Conversely, GeHCl3 can be obtained from GeCl3 by condensing HCl upon the latter. M.p. -71°C.

Preparation

passing HCl over powdered Ge (with heating): Ge + 3HCl = GeHCl3 + H2
