Polyphosphazene process. |
摘要 |
<p>A process for making an alkali metal alkoxide (e.g. sodium alkoxide) of a halogen-substituted alcohol (e.g. fluorine-substituted alcohols) by dispersing an alkali metal (e.g. sodium) in a cycloalkane (e.g. cyclohexane) or a cycloalkane containing a phenol (e.g., o-allylphenol) and adding the resultant dispersion to an ether (e.g. THF) solution of a halogen-substituted alcohol. The resultant alkali metal haloalkoxide solution, or alkali metal haloalkoxide solution containing phenoxides, can be reacted with a phosphotnitrilic chloride polymer to introduce haloalkoxide substituents or haloalkoxide and phenoxide substituents.</p> |
