Abstract : This document concludes the Office of Naval Research sponsored development of the Aerosol Fluorination Process and attendant chemistry. The introduction outlines and highlights the findings and conclusions of the twelve preceding technical reports spanning the period beginning September 1, 1977 and ending March 30, 1984. Included are the aerosol fluorinations of pivalyl, butyryl, isobutyryl and chloroacetyl acid chlorides producing analogous perfluorinated acid fluorides, in good to excellent yields. The aerosol fluorinations of polychloroalkanes produce perfluorinated polychloroalkanes in good to excellent yields however intramolecular 1,2-chloride shifts occur predictably and consistent with the known properties of alphahalo radicals. Chlorine loss and fragmentation are minimal. The aerosol fluorinations of chloroalkyl ethers including 2,3-dichloro-1,4-dioxane were successfully demonstrated, however alpha chloroalkyl ethers tend to lose chlorine more readily than beta chloroalkyl ethers. The attempted aerosol fluorinated of esters, alcohols, nitro-alkanes are described as well as the modestly successful fluorinations of methyl ketones which tend to form poor aerosols.
