A liquid phase process for making perfluorinated organic substances which comprises directly contacting in a temperature-controlled reactor a diluted solution or dispersion of a perfluorinateable, organic substance in a liquid, inert medium with a stoichiometric excess of fluorine gas, optionally diluted with an inert gas, to perfluorinate said organic substance at a temperature and a flow rate of inert gas (if used) sufficient to volatilize the resulting by-product hydrogen fluoride, removing said hydrogen fluoride from the reactor as it is produced, and separately removing from the reactor the resultant solution or dispersion of perfluorinated organic substance.
