Hydrogenation of fluoroacids with rhenium-fluorided alumina catalyst

摘要

A fluoroacid is continuously hydrogenated to a corresponding alcohol by contact with a catalyst comprising at least one of rhenium and a hydrogen reducible rhenium compound supported on a fluorided alumina catalyst support. In one embodiment perfluorobutyric acid is catalytically reduced to 2,2,3,3,4,4,4-heptafluoro n-butanol employing a fluorided activated alumina impregnated with perrhenic acid.
