ABSTRACT:
The invention concerns a process for purifying sulphuric acid, particularly after it has acted as a catalyst in aliphatic alkylation reactions.
It is characterized in that the sulphuric acid is impregnated into a porous organic or inorganic support, for example silica, and is then calcined at least once to eliminate organic hydrocarbon substances which the sulphuric acid may contain.
