| 摘要 |
The invention concerns a partially fluorinated alkane with the general formula RF [CF2 - CH2]RH, wherein RH is a substituent of the general formula CnHx selected from the group consisting of n-alkyl, sec-alkyl, tert-alkyl and cycloalkyl; RF is a substituent of the general formula CmFx selected from the group consisting of the perfluoro-n-alkyl, perfluoro-sec-alkyl, perfluoro-tert-alkyl, and perfluorocycloalkyls, with the proviso that only one of RF and RH can be linear, and that n > 3, the sum of n + m < 18 and that only either RH or RF are an n-alkyl or perfluorinated n-alkyl. These partially fluorinated alkanes find use as solvents, especially in medical applications where the properties of hydrocarbon solvents are not acceptable, in implants, and as an oxygen carrying blood substitute.
