Abstract
Abstract This invention relates to a process for the preparation of a fluorinated compound of the general formula R.sub.F C.sub.2 H.sub.4 OR comprising reacting an iodide of the general formula R F C 2 H 4 I with a percarboxylic acid of the general formula R 1 CO 3 H at a temperature and for a time sufficient to form said fluorinated compound; in said formulae R F is a straight or branched chain perfluorinated radical containing 1 to 20 C atoms, R is a hydrogen atom or --COR 1 , and R 1 is a hydrogen atom or an aliphatic or aromatic hydrocarbon radical.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
104 words
A process for the preparation of a fluorinated alkanol, ester, or mixture thereof of the general formula R.sub.F C.sub.2 H.sub.4 OR comprising reacting an iodide of the general formula R F C 2 H 4 I with a percarboxylic acid of the general formula R 1 CO 3 H at a temperature and for a time sufficient to form said fluorinated compound; in said formulae R F is a straight or branched chain perfluorinated radical containing 1 to 20 C atoms, R is a hydrogen atom or --COR 1 , and R 1 is a hydrogen atom or an aliphatic or aromatic hydrocarbon radical.
Claim 2
Dependent Claim
104 words
A process for the preparation of a fluorinated alkanol, ester, or mixture thereof of the general formula R.sub.F C.sub.2 H.sub.4 OR comprising reacting an iodide of the general formula R F C 2 H 4 I with a percarboxylic acid of the general formula R 1 CO 3 H at a temperature and for a time sufficient to form said fluorinated compound; in said formulae R F is a straight or branched chain perfluorinated radical containing 1 to 20 C atoms, R is a hydrogen atom or --COR 1 , and R 1 is a hydrogen atom or an aliphatic or aromatic hydrocarbon radical.
Claim 3
Dependent Claim
28 words
The process of claim 1 in which the reaction is carried out in the presence of a solvent for said perfluorinated compound which is inert to the peracid.
Claim 4
Dependent Claim
17 words
The process of claims 1 or 2 in which the iodide is added to the percarboxylic acid.
Claim 5
Dependent Claim
17 words
The process of claims 1 or 2 in which the percarboxylic acid is added to the iodide.
Claim 6
Dependent Claim
18 words
The process of claims 1 or 2 in which the temperature is from about 15° to 45° C.
Claim 7
Dependent Claim
24 words
The process of claims 1 or 2 in which the percarboxylic acid is an aliphatic peracid selected from performic, peracetic, perpropionic, or perbutyric acid.
Claim 8
Dependent Claim
29 words
The process of claims 1 or 2 in which an aromatic hydrocarbon capable of being iodinated is added to the reaction mixture to fix iodine released during the reaction.
