The Uses of GERMANIUM(IV) ETHOXIDE
It is a sol-gel intermediate for optical fibers and photosensitive.
Purification Methods
Distil it through a 10cm Vigreux column (p 11) under reduced pressure. Alternatively distil it through a Fenske glass helices (p 11) column fitted with a total condensation variable take-off stillhead. Fractionate it under reduced pressure using a reflux ratio of 10:1.
