The invention relates to an improved process for the manufacture of a fluorinated
organic compound, wherein the process comprises a fluorination reaction of an organic precursor compound having at least one
chlorine substituent and / or at least one
double bond, and said organic precursor compound is reacted in
liquid phase in HF (
hydrogen fluoride) serving as
solvent and fluorinating agent in the presence of a fluorinating catalyst, and wherein the fluorination reaction is performed in
liquid phase in a SiC block
chemical reactor, and wherein the reaction mixture is withdrawn from SiC block
chemical reactor, and wherein the process comprises optionally isolating and / or purifying the targeted fluorinated
organic compound.
