Process for the manufacture of linear hydrofluorocarbons containing end group hydrogen substituents |
| 摘要 |
This invention relates to a process for producing linear hydrofluorocarbons of the formula XCF2(CF2)nCH2F, where X is H or F, and n is 1 to 7 when X is H, and n is 0 to 7 when X is F, by a vapor phase catalytic reaction of HF and phosgene or sulfuryl chloride with corresponding compounds of the formula XCF2(CF2)nCH2OZ where Z is H or -C(O)OCH2(CF2)nCF2X.
