The invention concerns a partially fluorinated alkane with the general formula R F [CF2 - CH2]R H, wherein R H is a substituent of the general formula C.H. selected from the group consisting of n-alkyl, sec-alkyl, tert-alkyl and cycloalkyl; R F is a substituent of the general formula C m F x 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 R F and R H can be linear, and that n > 3, the sum of n + m < 18 and that only either R H or R f 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.
