The present invention relates to a process for modifying the fluorine distribution in a hydrocarbon compound, comprising a step of placing in contact between a hydrocarbon compound and a catalytic composition comprising a chromium-based catalyst, said process being performed in a reactor made of a material comprising a base layer made of a material M1 and an inner layer made of a material M2, said base layer and said inner layer being laid against each other, characterized in that the material M2 comprises at least 80% by weight of nickel on the basis of the total weight of the material M2, advantageously at least 90% by weight, preferably at least 95% by weight, in particular at least 99% by weight of nickel on the basis of the total weight of the material M2.
A process for modifying the fluorine distribution in a hydrocarbon compound, comprising a step of contacting a gas-phase hydrocarbon compound and a catalytic composition in the presence of a gas-phase fluorinating agent, wherein the catalytic composition comprises a chromium-based catalyst in a reactor, said reactor made of a material comprising a base layer made of a material M1, wherein the material M1 comprises iron and an inner layer made of a material M2, said base layer and said inner layer being laid against each other, wherein the material M2 comprises:
