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