An azeotrope comprising desflurane (CF3CFHOCF2H) and hydrogen fluoride (HF). The azeotrope can be prepared by fractionally distilling a crude mixture of desflurane and HF. Purer desflurane can be readily and easily separated from the azeotrope. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader quickly to ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the appended issued claims.
An azeotrope comprising desflurane (CF3CFHOCF2H) and hydrogen fluoride.
A process for producing desflurane (CF3CFHOCF2H), said process comprising the following steps:
A process for separating purer desflurane from a mixture comprising desflurane (CF3CFHOCF2H) and hydrogen fluoride (HF), said process comprising cooling the mixture to a temperature below which a plurality of layers are formed, and separating a layer that is enriched in desflurane compared to the mixture.
A process for separating purer desflurane from a mixture comprising desflurane (CF3CFHOCF2H) and hydrogen fluoride (HF), said process comprising solvent extraction using a solvent that can be easily separated from desflurane.
