Abstract
Abstract Novel, highly fluorinated hydrocarbons derived from the fluorination of alkyladamantanes, may be produced by known means, as for example by the process comprising contacting an alkyladamantane hydrocarbon, in vapor phase, with a fluoride of a transition metal (e.g., CoF 3 , MnF 3 , AgF 2 ) at 200°-400° C. The preferred adamantane hydrocarbons contain in the range of 11-30 (more preferred 12 to 14) carbon atoms and contain methyl and/or ethyl groups.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
30 words
Highly fluorinated hydrocarbons formed by fluorinating an alkyladamantane having from 11 to 30 carbon atoms in which the degree of fluorination is at least 75% of that corresponding to perfluorination.
Claim 2
Dependent Claim
30 words
Highly fluorinated hydrocarbons formed by fluorinating an alkyladamantane having from 11 to 30 carbon atoms in which the degree of fluorination is at least 75% of that corresponding to perfluorination.
Claim 3
Dependent Claim
29 words
The product of claim 1 derived from one of the following: dimethylbutyladamantane, dimethyloctyladamantane, dicyclohexylethyladamantane, dimethylcyclopentyladamantane, or dimethylcyclohexyladamantane, wherein all of the substituents on the adamantane are at bridgehead positions.
Claim 4
Dependent Claim
8 words
The product of claim 1 which is perfluorinated.
Claim 5
Dependent Claim
8 words
The product of claim 2 which is perfluorinated.
Claim 6
Dependent Claim
20 words
The product of claim 1 in which the degree of fluorination is at least 90% of that corresponding to perfluorination.
