  • Fluorination in tubular reactor system
    申请人:MINNESOTA MINING AND MANUFACTURING COMPANY
    公开号:EP0646557A1
    公开(公告)日:1995-04-05
    Direct fluorination of organics such as 1,8-dichlorooctane in tubular reactor system. Inert liquid containing organic feed is circulated through tubular reactor with fluorine gas for a time and at a temperature sufficient to yield fluorinated organic. Preferably, liquid and gas phases are separated from reactor product stream containing inert liquid, fluorinated organic, and any unreacted organic is recycled to turbulent mixing zone upstream of reactor in which fresh organic feed is added; and fluorine is added to recycle stream at end of mixing zone. Flow in tubular reactor is turbulent. Rate of organic feed and fluorine addition to process are independent of each other. Among process advantages are: Freon solvents not required; good control of reaction exotherm; and HF scavengers not required. Process useful for partial or complete fluorination.
