| GERMANIUM(IV) ETHOXIDE Usage And Synthesis |
| Chemical Properties | clear colorless to very light yellow liquid | | Uses | 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.
